Bluetooth A2DP Lag? - HD2 General

Hello peeps,
I wonder if any of you folks with an HD2, use it with Bluetooth A2DP and satnav?
My predicament is this...
I am a motorcyclist, and occasionally listen to music from my HD2 via a Bluetooth A2DP helmet. It works great, with good sound quality and no skipping of music tracks using Manilla Music Player.
I also have Garmin Mobile XT, which I often use in the car, and the voice prompts and directions work great through the HD2 internal speaker.
However, if I want to use Garmin Mobile XT with my BT Helmet, it works OK, with the exception that audio coming from Mobile XT seems clipped right at the beginning. For example, the instruction:
"Drive 3.4 miles, then keep left." - which is how it would sound through the internal speaker...
...will more often than not sound like...
".(point) 4 miles, then keep left." - when heard through the helmet.
As you can imagine, it would be quite dangerous to have to keep looking at the screen to confirm instructions, and you can believe how confusing this is when actually on the road and relying on voice direction only.
I have searched thorugh all of the HD2 forums for the tags 'bluetooth' and 'audio', found some similar issues that peeps were having with music player playback stuttering and the like, and tried some of the remedies offered by other forum dweller (like the increase file cache, line rate, etc), but to no avail.
As a computer professional, I am inclined to say that the symptons seem like a buffering or issue. But obviously, I am not a cellualr expert, so I will leave the really diagnosis for the pro's here ;-P
Perhaps one other lucky HD2 owner will have experienced (and hopefully had solved) a similar issue (perhaps not with the BT helmet tho ;-P).
Thanks for taking the time to read my post, and I'd greatly appreciate any feedback anyone has to offer.
Rgds,

Me Too!
I'm using a Samsung SBH-650 Bluetooth Stereo Headset, and I get exactly the same thing! I've no idea about a solution, but at least you know you're not alone.

I have the same with Jabra BT530. No reaction from HTC, no solution here.

i saw once a thread about a similar problem.
there they wrote that the bt-chipset which is used by htc for the hd2 is a Broadcomchip. They told, that there are some differences between the os and the chip and something about the problem, that it switches to standby mode too early or something like this.
this could be the issue. your phone turns the chip too early in standby mode and you cant hear the whole sentence cause it needs time to turn it on again.
sorry mate, im not having a solution, but thats something i read. maybe it helps.

Bluetooth is a slow (imagine RS-232) comms protocol that was designed primarily for local audio connection. EDR (Ehanced data rate) was brought on for high data rate stereo connections.
If you want stereo audio connection, simutaneous phone connection and GPS connection running while all the associated SW packages are running in your phone, then you are asking a hell of a lot of even a 2.5Ghz laptop!
PLEASE, lets get the device in perspective......

Hello,
Sorry for my english.
I'm biker too, i'm using a Parrot BT Headset and i've got no problem.
I'm listen to music (with S2P) and using copilot live at the same time without problem.
Sometimes instead of S2P, i'm listening to webradio (with Wunderadio) and using copilot live without problem...
Listening radio or music allow that the BT channel is always up.
regards,
Thierry

i'm not a motorbiker, but i use bluetooth headset for listening music.
When wifi is on, and there is not wlan accessible, bluetooth lags every 30 seconds when trying to connect.

I'm reviving this ancient thread, cause I'm having a similar problem with my HTC Amaze and it's driving me nuts.
Sound is played back with about 2 seconds lag, very, very annoying. Never had any issues with my Motorola Droid...
Can anyone explain why this is happening and if there is a possible fix/hack?
Help?!

WM6 bluetooth headsets losing sound

I appear to be having problems ever since i changed to wm6 for Trinity. My itech blueband bluetooth stereo headset is often losing sound when playing music. any way to solve this?
EDIT: solution page 4!

theese registry keys can be the sotution!!
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand]
"LaunchAPEnable"=dword:00000000
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand]
"VoiceCmdDuration"=dword:99999
or use this cab, its the same!!
rom is the latest official wm6. how i check radio? oh cool, i'll try out that cab dude, and post here the results
not working bro. shudnt my pda restart after installing that cab? i installed in main memory, and i'm now using my headphones. still got the problem. your registry tweaked the voice commander, my problem is with the bluetooth. 0_o
as in, i listen to music using my bluetooth headset, i hear
EXAMPLE: BONJOVI'S ITS MY LIFE
Its my ..(no sound suddenly).........Now and never, i aint gonna live forever!
the sound is lost but the music is still playing
Getting the same problem with iTech R35 bluetooth stereo headphones and offical Dopod WM6 upgrade (ROM 3.00.707.17 / Radio 1.46.00.11).
The headphones were working fine for the last 6 months with decent sound quality after pairing. Ever since I upgraded to WM6, either the headphones or the phone are dropping the BT connection after random intervals of between 5 minutes - 30 minutes. i.e. the sound suddenly cuts off even though the PDA is still playing music and everything seems to still be connected ( the BT icon is still displayed in the taskbar). If I re-pair again, it comes back for a short while, but then always cuts off again
This is the exact same problem I have with my R35 and WM6. I have figured out a way to make it cut out on a song (a different format wma). if i just play mp3s it will start to skip and then cut out completely after a random time. So I think its WMP I tried different radios and it still doesn't work....
help us anyone!
I posted a thread but no one was able to help...
http://forum.xda-developers.com/showthread.php?t=320809
I don't think it's a WMP problem,since I generally don't use that app. It's dropping for me with Resco Pocket Radio and CorePlayer.
Getting fed up with Dopod firmware. First, it was the 'no-bass' problem with the previous ROM. Now, it's this problem...! Can't they just release firmware without MAJOR bugs in it?!
I don't want to suggest this but do you think it has something to do with the itech clips?
when i use my BT stereo headset (plantronics pulsar 260) the music stopped sometimes, like described above.
when i disconnect my headset, the music plays normally over the phone speaker. no problem at all.
i guess its just another bluetooth problem.
when my phone is in my right pocket, and the receiver of my BT-set is in my left pocket, my body is between them, it gives the same problem( i am on my ATB at the time, moving)
very strange.....and no, i dont have any metal in my body. ;-)
Hi,
I'm using Touch 1.2 U-Clip and I have the exact same problem. So it's not just with i-Tech. I hope someone will find a solution for this problem.
Think its the Bluetooth stack
I am having the exact same frustrating problem - after checking to see if it was a Dopod error (tried closing down everything else on the PPC, tried other wired headsets), I have come to the conclusion it is something in WM6 Bluetooth, as I did not have this problem in the previous WM5 on the same machine with the smae Blueant Stereo headphones - mind you with WM6, I have full function with the Media Player, that is I can pause, next track, etc, whereas I couldnt do this with the WM5 version. WM5 had a really annoying high pitched whine, otherwise worked a treat.
So, in short WM6 has fixed the whine, has brought full features to the headset, but skips (blanks) the songs. Just before each "blank" I have noticed that it sounds like the song slows up - much like an old tape player running our of battery.
Now, I have no idea how/where/who to fix this, so anybody with even half a clue, please let all of us know, this is getting quite maddening!

bump for the thread. and yea man, i have the same prob. its like a battery dead sound, as the song goes out of tune etc
a slightly different problem
i use the INDIGO LITE rom, and i use OMIZ 5110 stereo headset, and i dont have the skiping problems described here, however since upgrading to WM6 the sound quality is terrible, i feel like tori amos is singing in my bathroom (which if was true could be really great) but alas, its just crappy sound quality... i tried changing the registry BITPOOL to 58 and played with all the values there known to man (at least to THIS man) but nothing helps...
Going by the devices that have this 'dropping sound' problem, it seems to only be affecting A2DP stereo bluetooth headsets paired with WM6 Trinity devices. Or are regular bluetooth mono headsets affected as well?
Personally havent paired a mono headset, but the problem I am having is definitely a stereo one! Any solution as opposed to taking to the machine with an axe?
Anyone found a solution yet?????? Please!!!!
I am also having the same sound dropping problems.
I have the same problem as well. I have just upgraded my rom to official WM6 rom. I'm using iTech Clip Radio.

Bluetooth drop out then audio spreeds up!

Hi,
Has anyone else noticed this issue, I have searched but found nothing...
When I am listening to music (on WMP WM5 or WMP WM6)
Every time it loses connection (which isn't that often and lasts for just a second or two) it's like my phone tries to catch up to where the track should be, it increases in speed and pitch until it has caught up with itself and gradually slows down again! It's like having a belt drive deck with a clumsy Bluetooth DJ built into my phone!
Unfortunately for DJ Bluetooth, I want to sack him.
I have a T-mobile Vario II, I've just upgraded to Schaps_WM6Pro_WWE_3.60a-0823 but this was happening on WM5, can't remember which ROM it was.....
Headset is an HTC S100 (which I would recommend if it's not the cause of this problem...)
Anyone?
Haven't seen that myself. How much free memory do you have when this occurs, and are you running a lot of other programs?
ive had this myself with a vario II on tmobile uk, using the windows media player, listening to an online radio station, the pitch bends up to speed the track up,
it got that annoying I dont use my motorola s9's anymore.
Does anyone want them? haha

bluetooth audio stutter

is it just me??
there aren't that many reports of this issue on the net. it was briefly mentioned on one of the reviews and that was it.
anyway, on higher bitrate mp3 playback, bluetooth headset audio stutters and skips a lot, even if the device is held very very close.
wifi was not running, 3g data was not on.
if you guys think the issue I posted on google Android's bug site is relevant, then please vote.

Desire as well?? wow..
i think perhaps ill try disabling the HTC Sense or something
just dont understand why no one's been complaining
whats the x10 like by the way...it looks really nice but someone somewhere said SE's skin is slow?
how much battery life do you get out of it?
I do have trouble using just a plain headset. I only get about 30cm range before the audio begin to stutter.
I've tried with two different Sony Ericsson headsets (HBH-PV710, HBH-610a) and a TomTom Go930.
Is it a software issue or hardware related? Repair?

am guessing it's hardware...
but perhaps it can still be helped by modifications in software
basically im still getting the same issues with a custom ROM
Got the phone replaced with a brand new, still the same problem.
Audio in headset is really bad, but in the other end they can hear me loud and clear.
Could it be poor output power from the Bluetooth transmitter in the phone,
while reception is good?
I've restored it to factory settings, and had WiFi disabled.
I've got the same problems on my Legend.
Both A2D2-profile and standard audio for talking.
No more than 80-90 cm before the static and noice occurs.
My colleague here at the mobile-store had the same problems on Hero, and now on his currently X10..
So to me this seems as an Android problem overall, but I can't tell for sure..
My Legend is my first Android handset, and I like it..
I only wish these blutoothproblems hadn't been here.. Should have been just the same as on my beloved Sony Ericsson handsets..
Got a new headset a Nokia BH-602 and the audio is a lot better, not perfect but at least I can hear every word said.
It's quite strange that SE HBH-PV710 and HBH-610a including TomTom Go930 just didn't work.
I'm just curious what qualification Android or Bluez did meet to certify for the Bluetooth standard.
Sorry to bump an old thread...
But just wanted to add I have the exact same issue, the bluetooth range is not very far at all, however it is a lot better then 30-60cm.. i'm able to go for about 2-4 meters with line of sight.
So i guess its usable as long as the phone is in my pocket which is fine.. just wish it was a little better like my previous phones where I can just leave it charging and walk around the house.
Bluetooth support is pretty atrocious on this HTC Legend.
Never had any problems streaming audio or using any of my previous devices with my car stereo for handsfree.
But this Legend is pants! - It won't work with Bluetooth Audio streaming at all - I just get static and some wierd clicking noises (using 2.03 latest official ROM) and handsfree connects ok - but then drops half way through a call causing me to lose my call at the time.
Any resolves for these bluetooth woes?
thanks in advance.
PS - Using it with my Pioneer FH-P80BT
I use my Legend with a pair of Sennheiser MM400 headphones. I have no stutter with bluetooth stereo (except minor cuts when browsing some intensive websites or typing fast in landscape mode). My headset works well even with the phone in my pocket (although it skips momentarily if I turn my head right or if my hand touches the bluetooth transmitter near the camera lens).
Perhaps some of the reported problems are caused by some background process using CPU cycles with high priority?
Incidentally, I highly recommend these headphones - bluetooth playback is of identical quality to wired playback. I don't know how Sennhesier have acomplished this feat but every other brand of bluetooth headphones I have used before have had intolerable reproduction of high frequency sounds.
I am having this problem as well...streaming music from my T-Mobile Vibrant to my radio via bluetooth. The radio is bluetooth 2.1 compatible and the Vibrant is supposedly Bluetooth 3.0.
I used to have a Mytouch 3G running Android 1.6 and I do not remember having this problem.
Same problem here !
am using Legend, and "Jwin Stereo bluetooth" headphones that needs "A2DP" to work, and its working clear but there is some silly cuts while listening mp3's and its disturbing me, i cant ignore these cuts coz are alot !
Please tell us if there is any way to solve it ...
Thanks..

Bluetooth Streaming Audio from Pandora to Car skipping

unfortunately when i connect bluetooth to my car radio the music skips about every 15 sec. very annoying. Anyone else having the problem.
I have an iphone 3gs that doesnt skip and works great. I love the Evo but bugs are continually showing up.
Its your internet. Try updating your prl.
i did update the prl before i tried it.
still does it.
I have a bluetooth reciever for my AVR and I noticed some skipping as well. Not as frequent as you are saying but if I moved more than 10' away it would be rather bad. The Bluetooth range seems to be poor. In a car I can't imagine you having a problem. I have heard of some issues with factory bluetooth.
I had same problem till I decided to turn off my wifi.. and it started working fine.. it just doesn't have to do with Pandora, its will any Music that you stream over Bluetooth..
Just turn off your wifi and it will work fine.
Thanks
Or just place your phone somewhere else in your car. Bluetooth has very lousy range (isn't it like 10 feet in perfect conditions?), and as such moving it a foot or two somewhere else could make a world of difference.
Its definitely not the internet. I could be at home in wifi with phenominal internet it even laying it off of my SD card. If im in a vehicle or on a bus, its pretty solid and works really well. I walk out the bus and walk around either to m next bus or to work and it fails to play for more than 4 seconds without skipping. And its not like a short, nuisance of a skip. It often stays skipped for up to 3 seconds at a time. Completely unusable. Happens however i connect my phone to any a2dp device. Tried tweaking the /etc/Bluetooth/audio.conference file as suggested in a couple nexus one/s sites, but unfortunately seems to be specific to those phones. This is making me hate this phone. Every other phone I've had in the past two years does this just fine. Whyis it having such a hard time with such a simple task that others have done perfectly? Even other Roms work better but i like also better than sense anyday. Maybe its a kernel issue?. I really want this fixed. But it seems like no one is even trying to work towards a solution. Not on the surface anyway.
Did you try turning off your wifi and any other unneeded services? The only time I have had skipping over bluetooth is when I have my wifi on as well, other than that it streams smoothly through my car stero and computer over bluetooth.

This.
If that doesn't help, then if possible, you should use an aux in cable to prove it's only a bluetooth issue. If it still skips, I'd try a new rom and/or kernel. A2DP performance seems much improved in CM7 compared to Sense roms.. or at least it seems better to me.
I've had the same skipping problem with my bluetooth earphones and evo. The only slight solution that I've had was holding the phone in direct line of site with the bluetooth earphones. When I do that, it doesn't skip as much.
Streaming bluetooth audio to car stereo
Thanks Anku13, your fix works. Just installed a Clarion CZ501 bluetooth receiver in my car, experienced skipping audio every 15 - 30 seconds once my Leo connected/streaming. Killing WiFi was the trick. Love not having an AUX cable lying around in the cabin.

[Q] Omnia 7 Mango: Bluetooth audio playback fails on everything except music

I have the problem that I can listen to music with my A2DP BT Headset (Philips SHB9001), but if I start Youtube, a game or the internal video player the phone fails and plays the sound over the speaker.
Is there any posibility to "hack" the phone (or something like that) in order to get that working?
I deeply hope that one of you a solution
look here
You made my day ...did't find that. Guess I searched with the wrong search terms. THANK YOU! I'll try it asap
this is useful for me too thanks
a bit buggy
FYI: Playing YouTube videos it's a bit buggy (BT Headset makes some kind of squeaky sound, it's stuttering ... don't know how discribe it better), guess that's why MS disabled it by default.
But I'am happy to have it . If someone knows this bug, and even better how to fix it, I would be glad to know .
Maybe it's wifi that is interfering with bluetooth. At least I have the same behavior on HD2 with wifi on.
