MHC19I Bluetooth Changes - Nexus 6P Q&A, Help & Troubleshooting

I noticed that after taking the OTA update to MHC19I that the bluetooth volume of a bluetooth audio device is no longer coupled to the android system's media volume.
The volumes used to be decoupled with Android 6.0. When 6.0.1 rolled out, they coupled the volumes. Now they are decoupled again. I'm wondering why they keep going back and forth on these design choices.
Anyway I was wondering if it was just a weird installation glitch with my 6P, or if others are indeed noticing the same behavior on their phones. Thanks for your feedback, guys.

There is no 6.1

I'm sure OP meant 6.0.1.

Same issue on my LG HBS-810.

I'm guessing it's because the coupliing has been problematic. For me, I can't set the volume low enough for a lot of media sources when using Bluetooth headphones. I've been using a buggy equalizer app to bring down the volumes, but I'm happy to hear about the de-coupling. I hope they figure out a better way to do the coupling eventually.

I just updated my 6P and the Bluetooth volume is still coupled to my headset volume. Darn.

I'm using powerbeats 2 bluetooth and they are still coupled. I'm running DU test build with the new vendor. Is there something I need to switch off?

I noticed this yesterday as well. Couldn't figure out why volume changes on my Jaybirds X2 wasn't adjusting the volume on my device. On the one hand, I prefer it as I just boost device volume to max and use the headphones to adjust listening volume. But, on the other, I wish they would stop going back and forth.

I'm actually using the same exact headphones that I'm experiencing this behavior with. Maybe it's just the Jaybird X2 that have this problem with the new update. I haven't had the chance to test this theory with any other bluetooth device, though.

Yeah, I liked it better when the volumes were synced up so it was easy to know what the volume was. But, like some have mentioned higher in the thread, they weren't able to get the volume low enough when the volumes were synced up. Man, this stuff never happens with iPhones. And no, not mine...but my wife has one! Android all the way since inception. But still, it's a tad irksome.

They've been going back and forth with this for years. TBH it's really frustrating. They did the same change when the Nexus 5 came out after the initial build the Nexus 5 shipped with at launch.

Sound too quiet, try this.

Hi all,
I've always felt that when playing music on my DHD that it's too quiet, when I've listened to music through my headphones I would say it's acceptable however when I've plugged my DHD into a HiFi or into my stereo in my car I could crank the volume to full control without it been deafening. I happen to find a fix yesterday by accident, I had my DHD plugged into my car stereo and the phone rang, I pulled the audio cable out and answered the phone, when I was done I put the cable back in and immediately I was like WTF just happened now, the music was much louder than what it was before I answered the phone, I would say it was about 30% louder.
I tested my theory by stopping the music and unplugging the cable, plugged the cable back in and started the music, while it was playing I opened the phone and simply dialled any random number and ended the call immediately, when it went back to the music it was most certainly much louder. I've tried it several times now and every time it makes it much louder than what it was before I make a call, I can now no longer turn the stereo full blast as it is simply too loud, just by turning it up to half way I would say it's the equivalent of what it was before when I had it turned up to the maximum.
I'm using Poweramp and I don't know if it's got anything to do with that, I will test it with the built in music player and see what it does. I originally downloaded Poweramp as I thought that the built in music player may be the problem.
i'll repet what you do and post some results... really want a louder volumen in headphones. I plugged my headphone in a Wildfire and it's incredible louder, no talking about an ipod! last week in a party i was ashamed when my friend put off his $50 cell phone and i plugged mine on stereo, so low volume....
wtf, that's true.. really don't understand what the phone turns on!! probably the same thing that volume boost turns on!!
Aha that actually works

works here too.. atleast on poweramp and soundcloud, didnt hear any difference on spotify

Haha! Tried it myself, and it works! Awesome!
I found using shazzam or sound hound while music was playing caused it to go louder. Seems to be when the mic is initialised. Noticed this two days ago

Interesting find.
I've noticed a couple of ROMS which suggest better audio volume by 20%.
For example this one. (Speaker Boost +20%)
So somehow, somewhere the bug or issue has been fixed or improved.

Not really, i'm using that rom right now, and what it makes is improve SPEAKER volume, not from headphone. I made my tests in Android Revolution rom and can confirm that headphone is as quiet as stock rom, and it is improved by the "call trick"!
Thanks for sharing! I was experimenting a bit, and it seems like the simplest way to boost the volume is to make a call while music is already playing. The call MUST connect though, or the volume will revert to normal levels. Tested with Winamp.
Maybe have one of the dev's ask to look into this.
If this is different from the already increased speaker volume output, it probably is a bug that can be fixed / feature that can be 'un-featured'
works fine
I had similar experience with my laptop. When listening a mp3 file, the sound coming out from my laptop seems like no effects, standard sound without bass and treble effect. Have to play a movie file first together and stop the.movie make the song hear with the effect.
I believe this issue coming from my sound driver. Using another OS in same laptop. The sound play normally with no issue.
For our Android, it's about the sound driver too?
well well, i just noticed that in the Android Revolution 4 (leaked gingerbread based), the sound is improved by default, no needing the call workaround, looks like HTC fixed the strange bug for the next version...
i just wanted to share!
edit: if someone could try to confirm it, i'll appreciate! =o)
sound problem
hey guys i'm new to this forum, i would appreciate if anyone could help me..
my DHD tones(just keyboard sound, lock sound, shutter sound) have came very low and i can burly hear it.. i turned all the volumes to the max but it's still very low, can anyone help me with that?

I had the same problem, go to the Market and download "Volume Ace".
MarkieSA, you're an accident hero.
I noticed sometimes my DHD volume suddenly were loud . If I restart the phone, it will go low . I couldn't find out how to make it loud again until reading your post. I'm using PowerAmp too . I think it plays a role in this case.
Thank you for this great finding.
Really useful little trick for 2.2 users, especially for peeps using stock ROM's without the 20% boost via custom kernels. I had tried some of the volume boost type apps before rooting but all they do is invert the phase of one of the stereo channels. All this does is give you a very tinny mono output which is no use to say the least.

[Q] HD2 low headphone volume

Does anyone have the lowdown on whether the HD2 sold in Europe suffers from the dreaded "EU volume limiter" and if so, is it limited to 100dB or 85dB?
Been a few threads on this subject already, and interestingly some people say they don't experience the problem, others do.
Currently using stock ROM 3.14.206.1 and wondered if the ROM version might make a difference.
I find that the supplied earbuds are quite loud but poor quality. They seem to be more sensitive than most standard headsets. If you substitute a decent headset the volume is just adequate on loud pop tracks with all controls maxed-out. It's too quiet to be usable on classical though, or on any low-level recordings. The same headset gives plenty volume on my HTC Wizard, as do a set of TDK earbuds.
I solved Android flashed 2.3.3 and using the original player with an app called Music fx, wow, it's a totally different world!

Was thinking of testing it with Android on the SD card anyway as that would pin down whether it's a software or hardware/firmware issue. From what you say it sounds like it's in the OS, so in principle it should be fixable.
Tried using TCPMP instead of WMP and this seems to indicate the player software isn't the cause.
I'd rather keep WM6.5 as the main OS for the moment as I've quite a few good apps.
Anyway, I've asked HTC if they can confirm whether this example has volume limiting or not. If yes, I'll be poking-around for a crack.
Strangely, results seem to vary between one startup and another. Last night I had it playing acceptably at 3/4 volume but today it's reverted to needing everything at max.
Not sure if Volumex fixes that, you can try though...

audio hiss after 4.4.2 update.

<<SOLVED>> The moto G Opamp is not very efficient. It struggles to go down to 2Ohm stable. This means average earbud type headphones rated at 16Ohms. will have hiss and other artifacts. Higher impedance headphones. 40-70Ohms have much better sq. Much above 70Ohms and I suspect the Moto G won't be powerful enough to drive them.... so, that's the sweet spot!
Hey,
Since I updated to kitkta4.4.2 I notice there is a significant background hiss listening with headphones.
As soon as you use an app that activates the audio jack the hiss kicks in, it is constant, not volume dependent. If you turn the volume down to zero, but the app keeps the sound output active the hiss remains.
when the app is closed, the hiss abruptly stops (presumably when the sound API deactivates the inbuilt opamp to save battery)
I'm about 90% sure this wasn't present under 4.3 or was far less noticeable.
I'm not being picky either, this is bad enough that it would make using the phone as a walkman at a low or moderate volume unpleasant. From experience I'd estimate the hiss at approx -20dB.. this is similar to the hiss you would hear from your average desktop PC fan at idle under your desk..
can anyone test this too, on 4.3 and 4.4.2?
Oh, and use earbud headphones or good closed cup ones. Open phones, unless you are somewhere very quiet won't give a good idea of the hiss..
thanks
Can confirm this on 4.4.2, too bad I didn't see your post before updating, as I don't really remember how it was on 4.3 :/
You don't actually have to use earphones, it's noticeable through the speaker, too (well I'm in my room alone and I put my ear close to it). However, I wouldn't say it's very significant - when using earphones I can hear it when muted, on the 1st bar after mute; on the 2nd you can't really say if you hear it or is it your imagination; and on the 3rd bar it's unnoticeable.
I can't notice any hiss in 4.3, even if I use a headphone amp. No clicking sounds either when the opamp turns on.

this is what I was worried about. I didnt notice any hiss before either, and I had it connected to a car stereo so would amplify the issue (if it was there).
maybe something did change in the audio settings/drivers then. I have already tried dissablying all the dsp stuff with no luck, still the hiss and click when the opamp switches on/off.
Maybe it was there before though, and it's bad luck with the phone, rather than the OS version.
I have got UK Retail 4.4.2 and I have tried to replicate this. I have tried YouTube, Spotify Play Music and TuneIn. I do not experience a hiss!

Under 4.3 to save battery I disabled apps I wasn't using, including the Audio Effects app, and google play. When you disable them it forces you to 'uninstall updates' which I didnt realise at the time, but I think may have been specific to the moto g, as you cannot redownload them from playstore, or update them.
Would someone be so kind as to upload the FULL apk of their google play and and Sound Effects, from their stock 4.4.2 build?
Im pretty sure this is down to the software API that activates the opamp. (as it is very distinct), it even happens when you activate audio by using the rocker to increase the ringtone volume!?!?!???
It sounds like listening to a really cheap mp3 player with a low S/N ratio...
** edit I mean 'Play Music' not 'google play'
Hi,
I actually just registered to say this was very much present on my moto g on android 4.3 and is still the same on KitKat. It definitely sounds like a cheap mp3 player. Does anyone know of a fix?
Thanks

Now this is getting weird. I think I'll install the ota to see how mine behaves. The G's audio quality decent enough imo. Probably above Android smartphone average. But what I like the most is that it's 100% silent, regardless of the volume setting, headphones or the amp.
Having said that, I will still get a USB DAC solution for it, which luckily has native support on both stock ROMs.

I don't know what you mean with "hiss", but since I updated mine (today - uk), i have started to notice some "clicks" in musics, that i didn't have before.
I was using PlayerPro, turned off the equalizer, uninstalled and reinstalled it again, and it was solved.
Google music, had no issues.

by hiss, I mean hiss. It is probably around 18KHz, and is similar tot he sound of RF interference on a stereo (alsmost like the snow screen sound on a tv).
It is not volume dependent so it is defenitely downstream from the DAC, and must be the opamp or downsteram from the opamp in the phone. It is most likely from a poor ground some where in the audio path (assuming the opamp isn't awful, anyone know the chip?). It could be due to the single board set up of the Moto G mainboard design. I'm guessing here, but if the PCB has the audio channel close to any of the ground of power channels, this would explain my hiss. If it is built to tight tollerance, this could also explain why some people have it, others don't.
In laymans terms, I'm saying the audio signal is 'dirty. If anyone has every used a PC with crappy audio on the motherboard, they will know exactly what this problem is like. When no program is using the audio driver, the board puts the audio to 'sleep', when you open a program that uses that audio driver, the audio wakes up and you get some hiss, noise through the audio and pc speakers. This is exactly what I experience with my moto G.
if im honest, it's unlistenable, however I'm a bit of an audiophile so I can appreciate for most people they won't see it as a problem..

I found 4.3 to already be noisy with the hiss when using my earphones, which have a low attenuation and so even low volumes sound loud on them. To get around this problem I bought an attenuator which connects between the phone and the earphones. Then I set the phone audio to maximum, and reduced the volume using the attenuator. Setting the phone audio to loud means the hiss volume is low compared to the volume of the sound coming out of the phone.
This is the attenuator I use:

this is a possibility, but its not ideal... sadly this is looking like a hardware issue not a software one though as if it was software, I'd expect it to be upstream of the opamp. The fact your attenuator solution works, is more evidence this is a downstream issue . (as implification induced noise increases with the square of the volume (assuming a logarithmic volume scale))
I'm on 4.4. I notice a slight hiss when music is coming out of the phones speaker, though its completely undetectable if the phone is at around half volume. No hiss when coming through headphones.

I have this problem with all audio activity on the phone, but the ringtone volume trick is the easiest way to demonstrate it.

Or even easier, just press the volume down or up button once in any direction with headphones plugged in. Regardless of what it was set to and becomes set to, you will hear a faint background hum/hiss be emitted through the headphones for a second. This is fairly normal on any phone and even most audio devices. I don't know what you expect really in a smart phone that costs £129 in the UK. It is a compact environment to build so much electronics into and will never be a hifi device.
I tested with 3 phones on my desk right now and they all have a hiss when you first do something to make audio come through the headphones like quickly play and then pause a track. In fact, one phone (Samsung Galaxy Ace Plus) has not only a hiss, but a screech/high pitched whine as well. All of these "noises" that are detectable, become undetectable when volume of anything is turned up past the first or second bar anyway.

This is a fair point, and I agree is not surprising given the phones price. I think the reason I have posed this question was to a) determine if it could be software related (4.3 vs 4.4.2) but It doesn't looks so. b) Is it universal, or could be a slight lottery and maybe my phone is worse than others. As some people say they definitely have no issue. (granted it could be subjective)
Also, I would say, although it is present in most devices to some degree, it is noticeably worse on this phone than any other I have had. Multiple sony erricsons, galaxy Ace, Nokias.. And my last phone Galaxy S2 had extremely clean audio production. (i compared directly with moto g).
I do concede I am an audio snob though, so don't like listening to poor quality. I never really expected to use the moto g for music, but would have been a nice to have.

Yeah, it seems to me too that you are a bit more on the audio than most people
By the way, I was wondering up to which levels can you really say that you hear the hiss? As I've said before, for me it's definite hiss when muted and 1st level, weird feeling on the 2nd and I can't hear it from the 3rd.

Depends on the music. pop music which has a lot of mids and highs, the hiss isnt noticible from notch 4 up maybe.
Quiet music, classical, R&B & hihop with a lot of bass beats but not many highs, you can hear the background his up to maybe 2 notches off max. But its acceptable from maybe half volume.
tbh it's more of a shame than an issue. I didn't expect this to replace a decent mp3 player, would just have been convenient is all.

Bluetooth Volume uneven and jumpy?

I've had some issues with newer Bluetooth music receivers on my 6p. I've read about many Bluetooth issues but not this. The issue is that when the media volume is changed on the phone, the result is very uneven and jumpy. It can be like volume 1=low, 2=very loud, 3=slightly louder than 1, 4 and 5 continuing while 6 once again is super loud. Also sometimes changing the volume makes it immediately jump back to something else. This is super annoying and dangerous as max volume suddenly is pumped out on the next to lowest.
This happens on newer Bluetooth music receivers, assuming Bluetooth 4.0. Older receivers I've had for years belonging to a lower Bluetooth version is still problem free. This leads me to believe that the problem is related to the link between android media volume and the actual Bluetooth receiver volume.
Has anyone else had this problem? Can anything be done about it or is it simply a bug that Google has to fix? Nexus 6p, v6.0.1 stock with some xposed stuff.
Yes. I have that problem. Can't imagine we're the only ones. Am looking for a google complaint page, with no luck.

This must be all 6ps, can't imagine just a few being affected. What I have noticed is that it only regards Bluetooth 4.x enabled devices. Below 4 is OK so it's just the newer stuff that screws up. Strange though you're the first noticing it.

Some kind of weird auto volume levelling while using bluetooth audio

Hi guys,
I am using bluetooth audio in my car and I noticed just after buying this phone, that when I set phone volume to 100% (in general, any volume above 67%), which I always do, since stock audio is not much powerful, volume changes rapidly during a song. To be more specific - I listen to electronic music and during every kick, volume goes down and up in the gaps between them, so it sounds like a wave. Higher frequencies or silent passages are loud as hell, lower bassy sounds are silent and this changes 2-3 times a second. It rips my ears off.
With my previous phones used in this car (LG G3, Zenfone Max 3), I never had this issue. I even tested some very cheap phones, every single one of them was ok, sound was not even distorted on max phone volume. On any bluetooth headphones it's the same case, so it's not car audio issue. Also when using corded headphones or aux, sound is perfectly fine as it should be.
What I already tried to fix it:
Messing with every setting in developer mode
Unpairing smart watch (just in case)
Tried loads of different audio players - with no EQ on, just flat
Reset to factory settings
Nothing helped. I lost almost a month with Asus "so called" support, I even shot a video for them with clear evidence what is happening. No help, except they tried to make an idiot of me. I get angry just thinking about that communication with them. Am I really the only one with this issue? I don't believe that warranty claim would solve anything and I really want to keep this phone.
Any help would be really appreciated. Thank you.
Try this, Goto Developer Options, activate the "Disable Absolute Volume" toggle (see screenshot). Disconnect and reconnect your Bluetooth connection. Hope it'll work out for you.

Actually, this was the very first thing I tried. Just to be sure, I did it once again together with disconnecting and reconnecting as well, nothing changed...
How about set whatever player you are using to be not battery optimized? I haven't been able to try any fix since I seldomly bluetooth connected to my car stereo. Or try, bluetooth volume control from Playstore maybe?

I am using JetAudio and optimization is turned off. Tried volume control you suggested, but it makes no difference. Sound is still messed up.
I use Shuttle as music player, bare in mind that every recording has a different mastering approach, thus volume levelling could be varied, especially on first pressed of classic records. Usually I am amplifying low signal wave records manually. But to keep away from such trouble, I suggest Spotify since it has normalizing feature, or turn on this feature if it is available in your music player.

I use poweramp.
It really help you. Give a try.
Do not use any third party equalizer app with Poweramp,use it's own eq .
I use CM's audiofx since it has somewhat subtle enhancement, aggressive sound tweak is nice but after 10 minutes or so, it tends to hurt my (old) ears. So most of the time I turn off EQ in order to preserve original sound, not that always works though, especially when it comes to mainstream records.

I am listening to my offline archive, not using Spotify etc. There is no way how the source file is affected - maybe one, but hundreds of tracks? Nope. If I have 67% volume or less set in my phone, sound is fine (but overall volume is low, since stock audio has no other amplifier. But when phone is set to 100%, no matter how loud I set car audio, sound gets wavy then. No other phone ever had this issue, I tried direct comparison as well.
I managed to do some test for a whole album on my way home, I could declare the volume level as well as connection was quite stable with no apparent bitrate drop. As a matter of fact it's superior than realme 2 pro which was suck big time in audio department. Although it is no comparison to my now dead lg V10, at this price point I can safely say I'm quite satisfied. The stereo is neither after market nor android auto.

Thank you for your efforts, so it looks like this is issue on my side. I already contacted seller and I will apply for warranty claim, because there's nothing more I can do.

I also have the same problem with my Bluetooth headphones (Sony WH CH400) which does not happen on my Redmi 3S (PE 9).
Songs can't hit the high frequencies and sound gets lowered down.
I googled and apparently its the stock Bluetooth stack that doesn't let the bitrate go above certain amount and needs some patching which Asus may not do.

@Junglista what did you do? found any workaround?

Not yet, I read briefly the forum you advised, but I need to dig in a bit more. Anyway, even this the closest cause, I don't believe that this is issue is bitrate related (but I may be wrong). I still can hear high frequencies in music, but when bassy part comes in, it's like someone turns higher frequencies volume down, so you can hardly hear them. And when bass is gone, volume rises again to "match" volume of lower frequencies. I still did not apply for warranty claim, because according to the forum you posted, I don't want to give up early and try patching the stack (if I will be able to somehow). Nevertheless, I know exactly what reply I would receive after 30 days at after sales service - issue was not found.

Hey! Literally i have the same problem. I have the same phone 4 gb variant. I previously used a phone with dolby and now this phone sucks. I think every phone unit has the same problem.

I've requested a developer to implement this in his rom. Let's wait and hope the issue to be addressed by our amazing community, else our only hope is Asus Pie update.
PS. I have the exact issue, maybe I explained poorly. lol.

I have the same issue with audio quality via bluetooth. Hope Asus will fix it

I've reported the bug on ZenTalk. I encourage everyone to report there too because it should be Asus' duty to fix this bug on stock rom.

Hey i found a way to tweak up things. The new omni player is on xda. It has a setting called output method. Select the OPEN SL ES. .ur problem will be solved.
