Bad A2DP bluetooth sound quality - Droid Incredible General

I recently got me a "Miccus BluBridge BBMR-02" bluetooth receiver to listen to music in the car. I noticed that music sounds a bit distorted. Kinda like if you use AUX input and make it too loud. If I lower the volume it doesn't help.
Now my friend with his iphone 4 connected to the same bluetooth adapter and his music is crystal-clear
I've tried few different roms (CM, stock, Redemption, etc) but they all have this issue. Is it a known issue or it's just my phone?

so your saying you need compression? Have you tried a rom that has DSPManager installed. That app does amazing things.

I've noticed on all of the ROMs that I've installed...with the exception of the Desire HD port...that if I launch whatever music app I'm going to use before the bluetooth headset is paired, I get a choppy audio.
Also, on many of the ROMs out there...there's an audio problem that has been described as "devil's voice." It has to do with how audio is processed in Froyo versus how it was done in the past..."stagefright" I think it's called. Most ROM chefs have a fix for it.

Crackling sound when playing audio from two programs over Bluetooth A2DP

Hello all,
I have noticed that when my HD2 is streaming audio to my car stereo over A2DP, if more than one program produces audio, then I get this horrible crackling sound as long as both programs are playing audio. When one program streams audio, the quality is fine. This does not occur when connecting my stereo to the headphone jack on the phone. Also, when streaming over bluetooth, the HD2 does not mix multiple audio sources, but instead stops the existing one and plays the new one only, reverting back to the existing audio when the new one has finished playing. This does not happen when using the headphone jack.
Does anyone else have this problem? Is there a fix?

You are not alone
Hi to all,
My HD2 is having the same problem.
Whilst playing music in the car over a bluetooth Jabra 3010 everything is fine till the voice of the navi is coming up. Again, every audio source it self and alone sounds nice but when they play at the same time...
I thought that the HD2 should fade between the sources instead of mixing them.
I am wondering that no other is coming up with this problem. Is no other using the HD2 the same way?
Thanks
Gabriel

Vibrant Sound Out + Car Aux In

Hi guys, my 328i has a built in Aux input. And it works great with my Vibrants 3.5 output jack. The only issue I have is, the volume is just not as loud as It is listening from the mp3 CD. The volume for both the phone and car is at full volume.
When I usually listen to mp3 cds, the sound goes up way louder. Is there a way to hack the phone to output louder through the 3.5 jack? Or if any of you have the 328, is there some option to do that?
I don't know about mp3 cds but as for official cds bought from the store, they are definitely a lot louder that the phone through aux jack. Same deal with my g1 before I got the vibrant.I'm sure once the rooting and custom recovery is all sorted out and we start getting some custom roms, the devs will include volume hacks just like they did for the g1.

I'm quite satisfied with the volume. If you need to blow your ears off boost up the EQ.
Actually, it's really weird. Through headphones I can equalize my Vibrant and iPod to sound the same, but through AUX, the vibrant is quieter (Same volume settings). Really makes no sense to me. It has to be something with the equalizer...
Edit: But it is in no way quiet. I have to turn up my car stereo by like 4.
Try a different cable or a higher quality audio file.
I play songs between 192kbps to 328kbps and have no problems. The volume is at the same level since I used my mp3 cd.
appreciate the inputs, i'll look for the equalizer on the phone.
Have you guys tried sending the audio thru bluetooth audio enable car radio? Pretty cool no cables needed
I can even listen to pandora and send the audio to my stereo

whoa, i'm going to have to try this out. any advice?
I have the Pioneer Z110BT Navigation and it has bluetooth audio. Just pair your Vibrant to the Pioneer then play any song on your vibrant using the music player. Click options then "Via bluetooth".
Then go to your stereo and click on bluetooth audio. Voila! Streaming music from your Vibrant to car stereo. The sound is also great!!
Not to hijack this thread but my one complaint of the phone is how low call volume and audio volume are.
Everythings turned up to max and this phone is roughly half as loud as my MT3G is set at 50%.
I have a Sony xplode and play through Bluetooth, I get great sound.
I have no issues with call sound or ring levels. I actually have to turn it down sometimes because its to loud.

I built a custom cable to connect the headphone jack to my Pioneer's IPBUS connector - it works great, and is very loud. I keep both the head unit and phone's volume on half way, and depending on the song I may have to turn it down, too.

AD2P Audio

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?
Sent from my Desire HD using Tapatalk
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.

[Q] Bluetooth audio quality

Is there any way to fix the bluetooth audio quality other than switching to a CM-based ROM?
My old phone over bluetooth sounds fine. My S4 via a wired connection sounds fine. My S4 over bluetooth sounds like everything was sampled at 32 kHz. All other equipment is the same, so I'm relatively sure it's a bluetooth-specific issue. My girlfriend's S4 does the same thing.
So, any fixes? I'd really like to avoid switching to an aftermarket ROM right now.

Random guess: Could this issue be caused by the adaptive sound feature? I'm not a true audiophile, but I haven't noticed a problem through my receiver in the car or at home.
Try playing something with cymbals and a lot of treble. Turn the volume up a bit higher than normal while still maintaining a reasonable level. The cymbals sound like someone is smacking a plastic grocery bag with a stick instead of being crisp and clean like they should be. I can then disconnect the S4, connect my old phone, and play the same mp3 without any sound distortion. Or I can play the same mp3 from the S4 via aux and it sounds fine.
Try it on both bluetooth and aux. If you truly don't notice a difference, I guess it must just be my phone. If it does do it however, you definitely don't need to be an audiophile to hear it.
My old phone had the exact same problem until I moved to JB on a CM build. The problem there is well-documented as existing on the S3 (try looking up bitpool settings), but I kind of figured they would have fixed it by now. I'm coming from the world of HTC, so I was hoping there is a fix for Samsung.
Sorry to revive this thread, but I have an update.
My car has built-in bluetooth for phone only, so no a2dp. I have a third-party bluetooth adapter that I'm using for music.
I've found that when both of these are connected, the audio quality (especially on trebles and guitars with distortion) is absolutely terrible. That was the point of my original post. Since then, I've determined that this happens ONLY when I am paired with both my car and my third-party bluetooth. I can actually pair and unpair from my car in real time and hear the audio quality immediately get better/worse. The quality gets worse immediately when it pairs, even if the car bluetooth is not in use (but still connected).
I've verified this is the case with both my phone and my girlfriend's S4. Can anyone with such a setup verify this does or does not happen for them? I'm thinking this is a bug with the bluetooth stack, and it'd be nice if it could be fixed. If anyone can try pairing to two different devices and confirm my problem, I'll start a bug report with Samsung. Otherwise I'll try another bluetooth adapter for a2dp.

Music skips and changes speed/pitch using Google Play Music through Bluetooth speaker

Hi guys. I am wondering if anyone else is having the same issue I am.
In no certain frequency, when I'm playing music through my Bose SoundLink Mini Bluetooth speaker from the Google Play Music app, it will sometimes skip and speed up/change pitch. It seems to happen on both WiFi and LTE. Haven't noticed it through plugged-in headphones.
I also noticed it when I had an AT&T Galaxy S4 through a Logitech Bluetooth stereo adapter and a Creative D100 Bluetooth speaker using the same app - Google Play Music.
I had both a Nexus 4 and Nexus 5 and never noticed it with either device.
All my devices have had the stock roms (non-rooted), and were always up to date. My Galaxy S5 is on Verizon. I haven't tried any music through the native music player app (such an mp3 or flac) but will update when I do.
Very annoying issue, especially for a musically sensitive person such as myself! I have sent multiple bug reports through the Google reporting process, and I guess I need to figure out how to send some to Samsung. Just wanted to see if anyone else had the same issues. Didn't see any other mentions of it on XDA. My apologies if there are similar posts on here and I didn't see them. Thanks!

I would root the device & keep the stock rom and install Viper4Android, It's the best sound app/mod that I have ever used and It will let you adjust all of your bluetooth sounds.
http://forum.xda-developers.com/showthread.php?t=2191223
For me It's worth rooting just so I can use Viper4Android..
I think it's the Bose device. I have the same issue with the Bose SoundLink Mini. Completely different phone than you. Droid Turbo. Never happens with any other Bluetooth headphones or with my car. It's very annoying. Any slight interruption in the audio stream to the Bose, and the music's pitch goes up like a quarter step. No it doesn't happen on any other Bluetooth device I have nor does it do it on the phones speaker or plugged headphones.
Apparently many people are having this issue with Bose SoundLink and similar devices. https://code.google.com/p/android/issues/detail?id=69397
I got a Bose Color SoundLink for Christmas, playing a station on TuneIn...after a little while there's a slight pause and the music starts up again at a faster speed! I was wondering if anyone else was hearing this and now I see its other Bose owners. Same thing happened with YouTube.
I have a rooted Note 3 running KitKat. Not upgrading to Lollipop.
Never happens if I use my LG BT earbuds or BT to my other little portable speakers.
