I think that must be because of the modem (radio). that is the part of the Rom tha controls all the communications. So that can be the cause.
Have you tried flashing a defferent one?
Hope i could help!
Edit: Here you can find all the Modems for our device!

I have noticed that music through both my wired and BT headphones sounds better on LPF than it did on LPY (as well as better than GB).
It doesn't sound as lifeless or distant as it did under LPY and GB.
I think it might be the way the system is processing the audio now, rather than BT itself being better.

yeah its really a night and day difference between any rom and LPF rom which is by far the best audio through bluetooth i got

Music player and A2DP

Hi all,
First of all, I have searched a lot but could not find an answer to my question -- if it has already been posted then my apologies.
I have a strange problem. I listen to music via A2DP using the TF3D music player. Everything works fine until I stop listening and switch off my headset. If I then want to listen to music again and switch on my headset, I can't hear anything (either through the headset or the phone speaker) despite the music being played by the player until I soft reset the device and start again, when everything works fine! I have now got a new device for my car (again using A2DP) and have exactly the same problem.
I don't really want to get another music player because the default player serves my purpose just fine.
Any suggestions?
Thanks a bunch.

How did you change the default music player and disabled the bitpool? Can you please explain the procedure to me?
Thanks
Hallo,
i usec diamond twaeks. http://forum.xda-developers.com/showthread.php?t=409540
You can change the audiomanager to windows and at bluetooth you can switch the bitpool to disable.
I have used the bitpool at high, and i have the problem, i change it to disable an i have no more problem.
i hope this is the bug and no random...

Hi again earthjumper,
I have changed the bitpool so let's see what happens. I still don't know how to change the default music layer to media player!
Does it better the audio quality in A2DP ?
Cause I think the Diamond performs very bad, sound quality is awful when I listen to the music through my Jabra BT-8010.
Hissing, bad sound quality, distorsion... What a mess... My Sony Ericsson k800performs MUCH better and acts as a real audio player. With HTC, I could'nt manage to have decent audio in A2DP...
Any tweaks in Diamond Tweaks?
Thanks !
Try the free version of Pocket Music. If you enable the equalizer and play around with the presets, it really sounds good on the Diamond, both through the speaker and through BT headset. All others I tried I had the same experience as you.
http://www.pocketmind.com/pocketmusic.htm
THX a lot for ypour quick answer !
I'll give it a spin and keep you updated.
I am afraid it does not work at all...
I still hear these distorsions/metallic noises in high frequencies. It not "earable". It still really creates unintentionnal sounds, hissing and noise, lots of noise...
I have tried any single MP3 player for my diamond but none is working... I guess the A2DP is defective in ths unit.
I am left with a very sad feeling of disappointment... It's another world when I plug in the default corded headset which came out with the unit. Nice sound, not the best of course, but a REAL increase in quality. Niothing is wrong in high frequencies, everything is much smoother and less metallic.
Thanks for your help anyway !
Any other tweak that I might use ? Registry setting, Diamond Tweak... ?
Sound is so unnatural it looks like there's something wrong with a setting... And I don't think the Jabra BT-8010 is faulty here. It could be, but I really don't think so...
@cornwall,
have you change any bluetooth settingss?
when i change the joint-stereo setting to disable, the sound over my bt-headset very bad.let it enable the sound is good, but low bass.

Thats not your Jamba, i bought yesterday Sony Ericsson Bluetooth stereo loudspeaker,
(MSB-100 i think) and the sound is terrible - you hear so much high frequencies distorsions that your ears suffers (and i'm not a sound freak!).
Tested the loudspeaker with old sony ericsson - no distorsions, sound quality 200% better..
Whats sad I haven't found the solution so far,
only SRS WOW (settings WOW Bass) brings me a little bit satisfaction..
Will try more tricks, maybe new ROM with new drivers ??
Hi all,
We seem to have drifted from my original query! I still have not found the solution. I tried earthjumper's remedy but it didn't work. I have tried other players but you can't control them via Bluetooth (i.e. play/pause/volume etc.). Windows Media Player is OK BUT every time it is run, you have to select the music and the library navigation is meant to be done with a stylus. The thing I like most about TF3D music player is that the music that you have selected to play (finger navigation) is always there even when you reset the device.
So my question again -- is there any solution for my problem or can someone tell me of a Windows media player skin which doesn't require a stylus?
Thanks and apologies for the long post.
I agree, I had an orbit 2, and the sound was fantastic through my car bluetooth stereo, now with the xda ignito the sound crackels and sounds terrible on high frequencys.

[Q] Bluetooth Audio Streaming A2DP Poor Quality

Hi Folks!
Recently got a bluetooth FM transmitter so i can go hands free in the car and use phones music player too
However the audio is very heavily compressed when using A2DP - no bass and the top end frequencies turn to mush - ie not good enough to use
Checked all eq settings and different FM frequencies, no difference
plugged the analogue audio cable direct from the phone to the bluetooth FM transmitter and immediately got perfect sound again
I dont see many poeple talking about this on this forum or many answers but the closest seems to be windows phones can access and modify registry settings to check and increase the bitrate
My current thinking is the bitrate (or bitpool) over bluetooth A2DP is set too low, or when the phone and FM transmitter pair the phone selects a bitrate that's too low for quality audio (but ok for calls)
My question is does anyone know how modify the bitpool settings on the Galaxy S please?
I am going to get a custom ROM and will very happy when the phone is really mine so if that's what it takes I'm up for it
Many many thanks!

Samsung Galaxy S
2.1.1 Eclair on 3 mobile network in the UK
Nexus Drive Transmit Pro (Bluetooth FM transmitter music and hands free car kit)
I have the Galaxy S on 3 UK since August. I use the bluetooth to transmit sound to my Samsung surround sound system (as I don't own a stereo). I don't notice significant quality issues doing this. Are you sure both your devices are supporting A2DP. Not all A2DP devices talking nicely with each other, so you may be failing back to the normal Bluetooth frequencies which are more focus of the vocal range. I'm looking a car stereo's right now that support A2DP so I can stream my audio from my phone straight to my stereo, my phone is becoming the centre of my entertainment!!
I'm running Doc's ROM on my phone, can't recommend moving to his Froyo ROM's and an enhanced kernel enough, my phone is working so much better with his ROM, but there are lots out there to choose from.
I am using A2DP in my car too and I find the sound quality being very good.
The thing is, the default Android audio player (Music Player) is pretty poor and often it lags for me.
Since I moved to MiuiMusic (Search here) all those lags are gone and it works perfectly and smoothly in my car.
Now, as pointed already to you, all BT devices do not communicate flawlessly between each other sometimes...
works great for me, streaming from the SGS to the car CZ 509 deck
i don't even carry CDs in my car anymore
even the lovely sub base sound comes through clearly.
nothing better like a Sonic Massage meanwhile you are driving
I wanted to create a new thread on this, but then I've seen this one. Is there no one with a solution except flashing cyanogen?
It could be a setting on your bluetooth receiver.
For example, I've got a pair of Sony DR-BT21G bt stereo headphones. When you hold a special button combination, it switches it from "high quality" to "any quality", and will just select whatever bitrate it thinks is best, usually, something that sounds about half as good.
Try looking in your manual for troubleshooting and see if there are any settings that you can change on the receiver itself?

Hmm, i using Sony MW600 BT headphones. I've checked the manual, but there's nothing about quality :/
But i dont think that's the problem anyway, as i tried Cyanogenmod and it got perfect quality then. But otherwise cyanogen is quite useless for me on my Galaxy S, its just too buggy. There must be someone who can change the bitpool quality on the stock gingerbread to the highest possible...
Exact same issue for me (as described by DJ LIBRE), I have a Belkin Wireless Bluetooth Music Receiver and the sound quality is horid... it's got nothing on AirPlay which I think is still kind of average quality!
I also wonder if there is a highbitrate setting that can be adjusted?
Running CyanogenMod Nightly #130 on SGS.
After getting used to listening to 24/96 FLAC's with the Voodoo Sound mod enabled with a custom built headphone amp and semi decent can's all I can say is BT Audio is a waste of time!
Has anyone noticed whether the music player was set to 5.1 surround mode? Had a similar issue where turning off the 5.1 fixed the sound streaming...

[Q] Audio Problem on FroYo (Call audio not playing thru jack)

This worked fine with the stock 2.1.. but when I flashed to 2.2 using Odin, I can't hear audio calls through my speakers plugged into the jack. Sound only plays through the earpiece or speakerphone.
Is there a fix for this? Do any of the custom ROMS have a fix for this?
Not to sound like a jerk, but have you searched the forums about this? This has been discussed quite a bit, so I'm surprised you didn't find it.
2.2 removed the option to play calls over external speakers.
Yeah I searched around for an hour then posted... it's really a dumb "feature" and I wish they would at least provide you a choice. Esp because I plug in my phone to my car and prefer to drive hands-free (sans bluetooth)
That's why I'm asking if one of the ROMs allow you to do that.

Bluetooth A2DP quality issue

So, I've looked around...does anyone use their captivate to stream to a car audio receiver? And if so, does it sound like crap for you too? With EVERY rom I've flashed, I have horrible highs, and really muddy lows if I use BT in my car. Friends iPhone 3gs- flawless. I've heard things about bitpool, music players, and bluetooth stacks. Some say the AOSP CM7 builds use the google bt stack, and it's better than what samsung gives us. Can anyone help me here?
My headphone jack has a poor connection to the left channel, so using the AUX cable, I only get audio out of the right side of my car. I've already replaced it once, would rather not have to again since I *should* be able to use BT instead. Hands free would be so nice, but it sounds worse than 128kbps mp3's...
I just started streaming over BT in my car and I was very pleased with the sound quality. To me, it sounds very close to the sound quality when plugged into the AUX port.
I'm running JVZ.

JVZ is an i9000 port, right? I'm not up to date on the current releases. I was wondering if the ICS builds had good audio quality, but no one replied when I asked in the dev thread. Are you using the stock media player too?
Yes, I am running an i9000 build. I just got the new car with Bluetooth, so I haven't had the opportunity to test on other ROMs, because (for the fist time on a while) I'm happy with what I am running.
I have used everything on my phone that makes "noise" including the Audible.com app, Sirius XM streaming app, standard music app and MIUI music app.

[Q] 4.3 bluetooth A2DP sound like crap??

Anyone notice the sound from bluetooth A2DP sounds horrible compare to 4.2??
Is it possible to copy some bluetooth lib files from 4.2 to maintain the sound quality??
My primary deviceis Sbh50. Nearly all my phone calls made with it. Also nearly 4 hours a day used for music. Did not get any difference from old firmware.

I got the same issue with MW600 bluetooth handset...
Same here with sennheiser m-550x and jawbone big jambox. No feedback from Sony yet.
Anyone, please help us!

We/I need the driver from 4.2. In 4.3, the alarms, notifications and ringtones go through internal speaker. My internal speaker will NOT wake me up in the morning, that's why I have bluetooth speakers, but in 4.3 all i can use them for is music and video soundtracks - even so, the audio over BT on 4.3 is awful and not as loud as in 4.2. (tested on both 4.2 and 4.3)
So we want the fancy 4.3 but with the decent 4.2 driver. Can anyone manage that?
