AD2P Audio - Desire HD General

Any of you using the Desire HD with a BT Stereo Radio and/or stereo headset. The sound quality sounds really bad to me. I had the same thing on my HD2 @ default settings, but fixed that by changing the linespeed in registry. (bitpool on older WM phones)
Have been googling and can't find anything of the sort for Android. Is there a way to fix the audio quality?
My brother has the SE Xperia X10 and it has way better AD2P audio quality, even though it's still android 1.6. So it's not an Android bug, but rather a driver/setting somewhere.
Also the range the BT has is really small, I have a Logitech Pure-Fi Mobile speaker, which connects through BT AD2P, the quality is lower then on my HD2 (after tweaking) and the range is only 5-7m, while the HD2 managed to have skipless playback and higher quality at over 15-20m...
Apart from this I'm really loving the phone . And my car radio has full support for the other BT features. Like skipping tracks (in Spotify) and dialing numbers via the address book on my car radio instead of on my phone. And see who's calling on my radio's display.

Hi there, I'm really interested in that too. Would you say it's just a slight problem of the sound quality or is it merely unusable?

If you use Bluetooth headset you can forgive about good music quality. that's all
if you need good quality audio in bluetooth, buy this:

You can compare the quality with 96Kbps MP3 which is really bad imho, but still usable. It's about the same on many phones though, allmost all are set to max 31 bitpool... But with windows mobile it was an easy fix.

As the source code is out, I hope the ROM builders can soon find a way to fix this.

Hi
I use a pair of plantronics 590e headphones over A2DP and the quality is brilliant! I have not changed a thing in the setup.
I wont play anything lower than 192kbs (most of my mp3 are 320kps) as i am a real fussy git when i comes to audio.
I have used the standard music player and tunewiki and both are perfect!
Are you atchaly using the A2DP or standard mic and mono sound protcal for calls?

My MM200 Sennheiser work flawless. Music is rich and crisp!

You won't know the difference if you haven't heard the difference between bitpool 31 and bitpool 58, it's like night and day to me. Even 256kbps MP3 sounds bad to me tho.
Tried different audio files and it's not spotify causing it. As my brother is also plaything through spotify at HQ settings (which is 160Kbps OGG, comparable with 320+ Kbps MP3) ...
Eagerly waiting for an AD2P fix for android.

When I have my HD playing music through my Car's Bluetooth the quality is also pretty poor.
For some reason I can't choose any of the EQ settings? If I could just try and add some treble I think I could put up with it!

Just tried playing music via bluetooth to my sony head unit in the car and it became so choppy it was painful to even try to listen to it.
Great phone but really disappointed that there is a problem like this as one of the main uses of my phone is for audio in the car.

I use a Sony Ericsson mw600 and the quality is not good. The same headset with my sisters itouch and it sounds great. Is this a hardware or a software issue?

You must be careful with the mw600 that it connects in the correct mode. As headphones NOT headset for music. If you get it wrong it will sound awful. You can check by tapping the Mic during playback, if you can hear it through the headphones you have it set up wrong

i had exact earphone, but it's just awful. first of all; htc doesn't make me choose any sound enhancements, other thing is, my 320kbps musics aren't different from 96 at all.
ps. i am an audiophile.

Imanaged to find my old iTech BlueBand headset yesterday and gave that a go. Sound quality was loud and clear and well balanced.
Shame about the delay though - it's worse than I'm used to. Video is pointless as the lag on the audio is far too much to be bearable.

Magician is a great Mp3 player

Just bought 2gig Ipod Nano for my girlfriend for chrismast.. i need to say this: comapre to my SPV M500, nano sound is so lame. I use the same sony headphone and the same mp3 songs. The nano got no bass at all. The Nano's equlizer doesnt work well, it make the sound more horiblle.
Magician + the bass and treble setting software, makes a good mp3 player. the bass is deep and the treble is great. just wondering how come there are so many people using Ipod with the stock headphones all over..
happy christmas

fashion statemeant. The included headphones are absoloute trash. I use my bose headphones, sweet.
For a £300 ipod, I would expect better headphones. Stop being bloody cheap appple.
I remember the good old days I used to get a case, firewire cable, charger, stand all included.
Who ever said something becoming popular was better. WRONG!!!!!

I don't know about Nano, but I bought Creative Zen Micro because audio section of Magician is too noisy and of poor quality. And I'm sure that special devices work better than multifunctional.

Hi parklife,
Which bass & treble software are you on? I tried one, don't remember which. Found it through the forum, but it made the sound horrible full of clicks & ticks all caused by the bass setting. On the headphone it was ok, but navigation or phone functiond with front speaker :--(
Regards, M
Ps. good to hear from you again
yah, those white head phones are a complete fashion statement. i got the nano, and to be honest, i dont use it at all, i bought it the first week it came out and used it that entire week,then i saw too many other people using it, and realized i was just some other "guy" with an apple. and i haven't touched it since then. its rotting away in one of my drawers hehehe
well, about the jam, i just installed pocketmusic like 4 days ago and i honestly cant beleive how amazing this is. listen to mp3s, no need to carry another device around (even if its as small as the nano) and still have GREAT sound quality!?!?! i'm using the headphones that came with the jam and quality is superb... i'm not an audiophile so i'm not gonna ***** if it isn't out of this world. i also got the 2.5mm to 3.5mm adapter so i can plug it into my car stereo. but the only problem... i got a 128mb MMC
but hopefully in two weeks i'm gonna trade in my jam for the k-jam and then i'll be gettin a 2gb mini SD :wink: (hopefully pocket music works well on wm5)
I use the jam as MP3 player in combination with MortPlayer. MortPlayer has a bass boost option which works great. You can find it in the effects settings. The Equalizer app mentioned isn't working that good because you often have to reactivate it manually. MortPlayer does this reliably and is for free.
As headphones I use Shure E2C which are a bit expensive (around 100 $) but sound very good with a bass boost. The mid-high sound quality is awsome. Also they isolate from environmental noise very well. In addition, I have the Expansys 2,5mm to 3,5 mm adapter.
What is concerning the sound quality of the Magician, I would say that a good MP3 Player definately provides better sound than it does. The sound is ok and powerful but there's some background noise audible also with high quality MP3s.
For me, I use TCMP player for all audio and video play back. It accepts almost every format that U can think of.
Now, I am planning to run my laptop in the car at a mp3/video file server using Apache(TCMP supports files playing over the network using HTTP). Therefore, # of songs I can play depends on the laptop's HD using bluetooth connection.
I,m understand what you are talking about I use the pocketmusic player, which have the best sound quality, and interface for me. I also have bought koss sporta pro headphones and 2,5mm to 3,5mm adapter, which produces great sound quality. When pda is used to listen music, I underclock it to 208mhz and it can play longer.
for me this is a new found side of the magician, i always new there were mp3 players and such but never gave them a shot. now that i am using them, can't believe i didn't do it before.
I still use my nano when working out and jogging because i dont feel like damaging my jam.
Also i started using resco radio. I connect activesync through BT and walk around myhouse while i stream my fav online radio, its great!!! it plays clear, no distortion, no buffering other than the initial buffer. Also resco radio has an option to record what your streaming, so a good song comes on, RECORD IT!! its great!
when i'm on campus i'll use the headphones supplied with the phone. but when i'm at home, i use my sony headphones (the ones that loop around the back of your head).
Me....i use the GS player. Though the interface wasnt that as goodlooking as the pocket music, or even the mort player....but the sound quality is just superb. So superb with the pocketpc audio bass and treblle enhancer software. In addition, i use the panasonic rp-hs-102. I jsut love the idea of having retractable wires......it just fits into my pocket perfectly.

As you should now, MortPlayer uses the GS Player libraries, so there should not be a difference in sound quality.
Anyway, there is a new Version MortPlayer 3.3 out, and the best thing, its free!
Just a question regarding the pocketpc audio bass and treblle enhancer software. Is there any way I can have it automatically "turned on" everytime I use my pocketpc? Tried putting it in the startup folder but still have to click the sliders before the changes takes effect. Thanks!
As far as I know, this is only possible with using a macro player like MortRunner which just imitates your stylus moves.
The equalizer software isn't needed, when you use the built in Equalizer functions of MortPlayer.
Guys..
apparantly that wonderfull bass/treble applet doesnt work on WM5!
I live by my magician with SONY NUDE-EX earphones.. like what parklife said.. it's totally awesome.
Now that i've gotten the Atom, I need to find an alternative way of getting that right kinda bass. Any help?
What's the best media player?
I'm currently using PocketMusic. It has lots of features the built-in Media Player doesn't have.
From the postings, it seems there are quite many other software: MortPlayer, TCMP,.... which i have not tried yet.
Which one is the best? In terms of:
1. User friendliness (thumb friendly, supports button mapping...)
2. Bass/treb/equalizer --> is this really important? It already sounds great without the enhancer.
3. Multiformat support (including video?)
4. Small footprint
5. etc.
The Magician makes good sound quality. I have a Sennheiser HD477, and also a Dell Axim X51v pocketpc. When comparing the Magician and Dell Axim x51v, the Dell Axim x51v wins with room to spare though.
I find the sound of the Magician a bit unclear, and not the best quality one would hope for.
Dell Axim x51v's quality is comparable to the high end Creative Media Players and the high end iPods with good earphones.
Magician is good, but not good enough in my opinion. And to be honest, WMP10 isn't the best media player available featurewise, but sound quality of WMP10 is definetly better compared to any 3rd party media player (on the Magician). I cannot hear the difference on Axim.

Can anyone try A2DP?

I was wondering if the audio quality and sound stuttering has improved by using BT stereo headphones with Blackstone...
I have a trinity and i still haven't found a setting nor a rom nor a BT stack which handles my samsung headphones with a decent quality and no stuttering...
My cheap nokia 6234 has a solid connection and a good quality sound compared to the trinity... Plus, the A2DP connection slows my device down so much you have to pause if you want to do anything with it...
So if anyone could report about using bluetooth headphones with Blackstone, I would be very grateful as that would help me decide whether to buy or not
Thanks a lot

Great
I have the Touch HD for a few days now with the BH S100 HTC bluetooth headset. I have to say that the sound quality is great. It is even better than my conventional mp3 player.
Stable, never lost connection, etc.
Hope this helps.
I tried it today, with my Sony-headset.
It seems to stutter, though, for the five minutes I tested.
I have the Blackstone from seven day and the A2DP is OK with my Sony_Ericsson HBH-DS200.
The sound is very good and the pairing with the phone is immediatly in about 1 second.
Regards
reasonably OK with my Jabra BT620s. However, quality in BT A2DP is not really comparable with wired headsets, and i got some losses when passing nearby EM sources like wifi, etc.etc.
I needed to enhance the quality with Schaps Advanced Config Tool.
Alpine radio
I have an Alpine radio with bluetooth capabilities in my car, and for the first time I have a great connection with my HD. My Touch Diamond stuttered.
Thanks a lot everyone!
I guess it depends by the headset model and interferences then...
I'm still looking for a shop which would make me play with it for a little while...
i have a pioneer deh 700bt and the headunit set up was easier than the nokia n95
streaming music was a bit weird, the quality was very weird, kinda like very low bit rate streaming on mp3s at times, then fine again.
my n95 music used to pause when i took the key out of the ingnition and the stereo turn off
however the HD just keeps playing, but not through the speaker phone....just see it still playing
bit disappointed, and looking for a fix
I've only played for 10 mins, so i'll let you know if i find some more.
I have an Audi A3 from 2005 with a original BT carkit.
Can I use my HD to play some music ?
I can make phonecalls without a problem, if I adjust the volume of my carradio the volume from the HD is also adjusted.
But is there a possibility to play some music ?
Has anyone tried the Plantronics 855 Voyager stereo headset yet?
Also, I'm currently using the Jawbone 1 and noticed horrible interference/noise in the ear piece when the wifi is on, anyone else experience this?
I've never had any problems with the diamond and now with the hd. Like the senior man said, you need to increase the bluetooth bitpool values either in the registry or by using schaps tool. The difference in quality is immense - low values will make high bitrate music sound 64 kbps so you need to change this. Of course, the higher the bitpool the more chance of dropouts but I run at 60 and rarely, if ever have any dropouts.
Sennheiser MM200
Now if tested for almost one day my HD with my new Sennheiser MM 200. Amazing!!! The use of the MP3-Player switched with the use of the remote control to a new level. During sport display can be switched off(no need for touch display-less power consumption (try to give a more compareable info in future)), full control of play/pause/fwd/rwd/volume function. There is no delay of the HD in using the remote nor any transmission interruptings. Now the HD is with armwrest a perfect sport companion. The sound of the earphones - haven't had any better sound (and i've tried a lot of earplugs). Neckstrap fits perfect, mic in perfect position, clear speech and due to perfect noise reduction of the plugs even in noisy areas perfect understanding.
The Sennheiser was just charged the first time - i'll report the stamina.
So far -
I am using the i.Tech S35 bluetooth clip also on my HD now, and sound is very good, with WiFi on. Advantage of the clip is that one can use any headphones with it.

It's not possible to play music, only phone functions are available.
I've tested the HD with the PARROT MK6000 and everything works very fine, also A2DP, Quality is good.Phone Functions great, Phonebook synchronize works perfect

final conclusion the sound quality from the touch hd really really sucks

Ok well I went thru many testing options when it came to the sound quality out of the touch hd compared to other devices.
1- to test the sound quality I used the following players
a- core player 1.3
b- pocket music 5.1
c- touch flo player that came with the htc
d- pocket player
and all sucked big time, when I connected the device to a sony adapter cassette in the car. The sound is really awful comapred to all the devices I own like the iphone, or ipaq. WHAT THE HELL IS THE PROBLEM. I tried to use the equalizers in all the palyers, aslo the audio booster but the sound sucks. I tried to use also an adapter that has 3 rings on it to connect to the htc hd.
Please am I missing something here???

It all comes down to how you have your HD setup. First, check the app called "Audio Booster", it comes out of the box configured to sound like ****, turn it off. Get the HD Tweak app and disable the 100db sound cut barrier and use the graphics equalizer that is in your chosen player. I use Mortplayer and now I can say that the playback with my Sony in ear headphones is really good.
HD Tweak has a setting that should reduce the ring delay.
me I also agree that audio booster sucks, when switched off sound gets much better
Also, a cassette adaptor is likely to limit the quality you can achieve. Better to compare through a decent set of headphones.
Seriously man, putting that line in your topic title is misleading.
I've tested Touch HD's sound on high quality headphones (Ultimate ears Super.fi 5XB) and the sound is great even on stock settings. In fact, my iPod is getting a lot less playtime since I bought THD.
Did you notice any hiss in qiet moments or on gaps between tracks? For me that is exactly the same as it was on Kaiser
Yes I noticed a hiss and a small gap in a song, i even installed the hd tweak, and sd tune up. But still the problem remains.
I am not talking about using it with headphone, I am talking about using it on my car stereo, thru a sony cassette adapter. Aren't we all in need for a great sound in the car, and why all the other devices sound great on my car stereo except the hd
I only have Shure E2C for "in move" devices, but I remember them sound much better than with Touch HD

I'm having similar troubles here! Turning down the volume to about 30% on phone and using car stereo volume helps a bit. Also try different players and get rid of the car charger! It truly sucks as my other ppcs & mp3 players do not need tweaking AT ALL! They all play & charge at the same time.

Is this a joke? Sorry I am confused. You are talking about the needed GREAT SOUND an than you are talking about some funny CASSETTE ADAPTER?
Conclusion: If you want great sound in your car, you should not spend all your money for a phone - How about new car stereo - some of these funny new toys supporting funny things like LINE IN or USB-MP3 or Bluetooth A2DP / AVRCP (handsfree profile). I had a really hard time to remember how a cassette looks like.
The next one blames HTC becauese the HD doesn´t sound good when connected to the phono-in of his late ´80s stereo.
From my point of view, the HD serves a better quality as most of my "old" mp3 Players, better than my iPod but not as good as my MP3 from Philips. Even so, yes i´ve noticed these short lagggggs in playback. I wouldn´t have noticed them if someone here hadn´t mentioned them.... so thank you
What´s next? 8-track tape adapter doesnt work right on your high end car stereo?

My Kaiser didn't had any... But in the HD I notice it happens once in awhile using bluetooth phones. But in general i got tell the SOUND ROCKS.... (after you used HDtweak to disable the 100dB limit!)
The title is really misleading for a new costumer, it's not true that the sound output sucks in my tests it resulted better than my old n95 8gb and an ipod touch.
For the average costumer the sound output on headphones is good.

If you are noticing differences between devices when using the tape adaptor in the car but not when using headphones, there has to be something different in the setup. (Or you're using apple-grade headphones )
The tape adaptor is designed to mimic the response of headphones, so that the player doesn't see a difference. I second the suggestions of turning off the audio booster and 100 dB cutoff, as these can and often will interfere with the signal.
Once you've turned off the equalisers, try setting the volume on the player to about 50 - 70% and then adjust the car stereo to your required volume. There may be a mismatch when the HD amp is either running at really low or high outputs, causing distortion.
It would also be helpful if you could characterise the type of problem you're having: Hiss, low level overall distortion, distortion mainly on peaks, poor frequency response, etc. Different effects will typically have different sources.
NB: don't rubbish the tape adaptor! It serves its automotive function for me as well, although I'll take my Grados and Westones when the wife isn't in the car
Edit: Just did a quick comparison with my iPod Nano and there is very little between them on good headphones.
I can't confirm that at all, using Koss Porta Pro headphones and Coreplayer for playback (audio booster off, 100 db limit disabled, equalizer enabled) I get fantastic sound for a portable device, something's wrong with your setup.
Just connected my HD to my Z-5500 500W sound system using the analogue connections. It sounds perfectly fine to me, as good as anything else analogue i have connected.
I'm using my Touch HD with a pair of Sennheiser HD550 and some BOSE Quietcomfort 2 headphones. By no means super high-end, but good enough that I can say that the sound on my Touch HD is very good. No hiss at all, good clarity and overall good sound.
I have installed hd tweak and I tested the sound with Coreplayer and the inbuilt one in TouchFlo.

Well Shure E2C are isolating earphones you put into ear channel. They are very sensitive, you hear everything louder than on any other type od headphones especially noises. And there is hiss/noise trust me. I also have headband Sennheiser HD580 & PX100 they are ok with HD. The trouble is that there is no hiss/noise at all if I plug shure's into my computer (SB X-Fi Extreme Music) and quality is also bit better.
I also have isolating earbud type headphones and the HD sounds no worse than any other Mp3 player ive used, including an iPhone or N95 8GB. Its not a high end audio device, comparing it to a 24bit reasonably high end PC sound card is not fair.
OK pass, I'm an audio-freak type. Maybe I just expect to much from HD
using UE triple.fi 10 vi's and the sound from my MP3's on the HD is very good... i have no complaints.

A2DP sound quality issue with Galaxy S 2

Hi guys
i read xda so much, but i don't write as well
i have a big issue with my galaxy s 2
i use a bt car stereo, with a2dp and avrcp support
i used to stream all my music collection from my iphone4
now i got my sgs2 and i love it... but
the audio stream looks "limited"
it seems a bandwidth issue, or i don't know a quality issue
with iphone4 i streamed at full quality, now the sgs2 sounds a lot worst
other than that, i have to disable wifi because if on, the music is choppy and skips a lot
with wifi off, the stream goes well, but it sound bad...
sorry for my not so perfect english... i hope there is a way to improve sound quality because i "live" with a2dp on in my car...
That's strange. My a2dp stream actually sound better from sgs2 than it does from my ipod touch 2nd gen, iphone or my computer (bluez).
Receiver is a belkin stereo a2dp receiver.
Are you sure that it's not in handsfree mode? Long press the a2dp device in bluetooth settings and there should be an option to select it to be a media device, make sure it's checked.
thanks for the reply gvoima, no it's in media device mode
i think the problem is the bitpool
i've got the same problem of this guy: http://forum.xda-developers.com/showthread.php?t=708685
there is an mp3 sample of the problem in the first page

I got a belkin stereo receiver as well, but it sounds bad and choppy, just like the topic starter described. Though still compressed (this is a known issue for A2DP due to bandwidth limitations) songs sounds much better from my Nokia E52 work phone.

The "but my (insert phone) worked better" isn't really valid. For as many people who make that statement there are an equal number who are shocked that the SGS2 works where other phones haven't. This is kind of like the Wi-Fi issue. When two pieces of equipment don't interact well you can't just blame one of them.
In my car and on my Yamaha YSP-4000 the SGS2's Bluetooth works better than any phone I've used. That includes the HD2, G2, and G2X. The sound is much more defined and headset controls (random and repeat) show available for the first time. The SGS2 also feeds track info to the car which none of the others did.
Bluetooth connections and sound quality are always a big YMMV.
My Sony MW600 sound great, I use to have a Motorola Defy , and it use to have an "Enhanced Stereo" option in the blue-tooth menu, the Samsung S2 does not have this option.
@BarryH,
Oh I know, I not blaming the SGS2. I only think the SGS2 out sound to it's output module which is somehow less suitable for the kind of compression, maybe set by the Belkin module. Actually I'm currious if there would be ways to change the way the SGS2 sends sound signals via A2DP

LG's implementation of Bluetooth drove G2X owners crazy. Check out this thread from the G2X forum...

Maybe it will help. The only other solution for the G2X was installing an AOSP ROM.
Well, I tried it (Bluetooth Fix Repair), but off-course that tool is for a problem the SGS2 does not have.
From the tinkering I've done now I know.
- Having MusicFX installed does not make a difference
- Video players running ffmpeg codec do also not make much difference in sound quality
- The -type- of file does make a difference, i.e. low bitrate files play better
This makes me think, is there a music program which can resample/recode music before playing. I'd rather have software do that than A2DP do it badly, or is mono output (other than all the tools enabling playback on mono headsets which is for pre-A2DP headsets and thus something else) possible?
Edit /system/etc/bluetooth/audio.conf
Uncomment "Master" option and set it to "True".
Uncomment "MaxConnections" and set it to 3.
Most Android devices have this file configured poorly by default, those 2 settings should help though.
I'd suggest also enabling HFP and AutoConnect.
Great! That definitly reduced creaking/noises and even the occasional stuttering music!
Since you seem to know your stuff, would there be a way to send a mono signal to (only) the A2DP stack and would this decrease the 'tin can' effect? I'd rather have better upper tones than stereo.

Thanks for the suggestions...going to try this and see if the sound quality improves in my car stereo.
Till now the best A2dp sound quality was on my Nexus S, but that was with the help of custom rom development and vodoo sound. Worst was the g2x.

Ok guys, I think I might have... accidentily... run into a phenonemon.
I tested my phone on a Creative D100 wireless speaker it it went great, no tin can sound, no hickups.
This proved to me that there had to be something wrong. Now when I was posting here earlier I was listening a lot to music and at a certain moment I thought... wait I'm not hearing a tin-can sound anymore. However, later on while testing I heard it again so I thought I imagined it.
Powering off the phone and powering on again I was able to create this again. No tin can sound... however a lot of hickups (as if a lot of data had to be sent and it didn't quite fit). I made a call to my work phone (sound on the handset) to test and then the tin can sound was there again, no hick ups anymore though. Strangely enough a haven't been able to replicate the 'no tin can sound but hickup situation' though by powering off and on again. Tried after playing on the Belkin on the D100 again and no problems at all, great sound and no hickups whatsoever.
It appears to be a bigger issue with android connected to the bitpool setting the bluetooth receiver desires...

Let's hope the upcoming Cynogen can fix this issue.
I too felt that the A2DP sound quality on the Nokia BH103 is crap as compared to my Nokia 5800 (sounded even better than stock wired headset). It also uses a lot more battery, I find mediaserver using a lot of battery.
How do we escalate this to Samsung?

That sounds like it's using the hands free profile instead of A2DP. You could try going to the options of your bluetooth headset on and untick the "Phone" box, and make sure "Media" is ticked.
I have generally decent bluetooth audio using Motorola T505 to broadcast FM to the car radio (must get around to buying a proper BT head unit, or a new car with one built in...). Most of the problems I have are interference with the FM signal rather than dodgy bluetooth.
However, I do see this kind of bad distortion on the high end with certain pieces of music - generally the solution is to turn down the volume on the Note a couple of notches and crank it up on the car stereo. I assume some of my tunes are just recorded/ripped REALLY DAMNED LOUD, it seems to mainly be things I ripped myself years ago so I probably didn't pay much attention to the levels at the time.
If you lower the volume from the Note does the distortion disappear?

No, still there. I'm using Galaxy note and noticed a similar problem, both with a pair of Plantronics BackBeat and bluetooth car kit FM transmitter. It sounds pretty fine on my Archos 5IT that is running Android 1.6 and my Nokia N900 running Maemo. My note is currently running on Android 2.3.6 Rocket 12.
Bluetooth stereo sounds great for me using Sennheiser MM-200...
If you have exceptionally bad audio quality, it's probable that the headset is being used in handsfree audio mode, and not media mode. If you go to settings>bluetooth, and click on your device, you should see which modes are ticked.
Also, some people have reported better bluetooth audio quality with the LR1 modem. See here:
