Your bluetooth streaming experiences

I stream my music from my phone to my car's JVC stereo unit via bluetooth. And I've noticed something and want to check with the community.
On TW gingerbread builds the audio stream is very poor. Lots of static and overall poor quality.
Then came the first few ics leaks. All of a sudden music over bluetooth is magical. To the point where I can't tell its being streamed via bluetooth and not aux.
Then came CM9 and AOSP, which also worked magically so I've been using them. But they have semi-poor battery life and issues with SD cards.
So I go back to a TW base ics leak because I like that everything just works and wanna be simple for a while, some of the new FE ones to be specific. And now all of sudden the bluetooth streaming sucks like it did on gingerbread.
Why? What changed? I'm pretty sure that around the FD teens leaks the bluetooth streaming was still fine. Not sure when it started to suck cause I mostly have been on AOSP. Does the modem affect the bluetooth radio? kernel?
I have exhausted all my knowledge and testing and scenarios that I can think of and cannot figure it out. Anyone know why this might be happening?
Anyone have similar experiences?

My Bluetooth music streaming has always been solid. Idk what happened in your case but i believe BT Stack libs were updated or something like that lol

I stream via BT to my factory VW deck. I've had great experience on GB and the latest ICS leaks.
The early ICS leaks I noticed some popping, but I haven't heard that in awhile.

Could you direct me on where they might be located? Would you think it feasible to switch them with ones from cm9 and that might fix my issue?

You think modem is the culprit?

I think a bad bluetooth experience has to do with your receiver. I drive a ford with all the myFord hoopla and it used to work more of less but there were bouts when it was terrible and unusable and i had to pull the fuse to reset it. However there was a huge update to the software and I have not had a single problem with it since then. Streaming music, answering calls, phonebook download, receiving and sending texts all work great for every rom i have tried.

This is what I thought at first. But it doesn't explain why AOSP roms always work perfectly. Doesn't matter which one. No problems, perfect audio Yet GB and now the new ICS leaks work so terribly. It doesn't make sense. And it doesn't explain why TW ICS used to work great and now they don't. I can't figure out what is changing that is causing the difference.

I hated the GGB BT streaming. Too much popping and crackling.
ICS has been very good to me streaming, quality is superb. I haven't noticed a reduction in quality with FE10 from FE07 and earlier ICS builds. What I did notice is that with FE10, the pause/play button on my remote now works again for Google Music, which is nice.

Head sets?
I'm a fan of noise attenuating ear buds, ala JVC ha-fr50 whilst I'm driving for podcasts and phone calls.
Are there any decent BT ear buds like that? Something that blocks out a fair bit of the external road noise. As for the mic, I've had some folks say I sound fine but a little distant with the mic on those ear buds, but normal and clear when I practically eat the thing. I've never used BT ear buds or the streaming but from what you guys say, it seems sound quality isn't much of an issue.

No issues streaming BT on GB strongsteves ROM to my Sony receiver.

Thanks for the responses guys. Apparently somethings changing on my phone with each flash or my Bluetooth radio is faulty in a slight way. Not in a big enough way to warrant a replacement uunfortunately. I'll see what I can figure out.

What are you streaming through? My vw is a pita, but after some slapping it around I can usually get it to work.
Early leaks of ICS had popping, but that is gone in the later leaks.

Streaming just music from my sd card. The deck also supports bluetooth calling and connects to that at the same time. I never use it though, unless someone calls me. Connecting to the unit works just fine for all roms and versions, just the streaming quality is drastically different.
I was actually gonna see if i could get the unit to connect just the media and not the phone and see if that helps. I really don't know what else could be causing it. I can't pinpoint anything thats common or reoccurring each time the quality is bad.
All I know is AOSP works. Everytime. But why?

After some digging I found these threads here and here. Both by the same guy.
It appears he was onto a solution or at the very least a cause. Unfortunately, it appears that once ICS came out, the problem was solved by Samsung and it was quickly forgotten with no solution.
Except now, for me at least, the ICS TW roms don't stream properly anymore.
Also, just had a thought. When going between roms, I have skipped over flashing Caulks format all and just wiped data. Never had any problems, but I remember reading back in the hero days that not formatting every partition leaves some old files on the phone, and possibly bluetooth files are stored there? Should I try flashing a tw ICS rom after an AOSP rom without running format all?

I don't think that would be the case, but def worth a try. Lets us know since I would LOVE to be using my BT audio, but it reduced the quality too much for me, no popping etc, but, too poor quality for a good stereo/speakers and my prude-ears

Well I did try everything I could but came up empty handed. Theo only way I can get good Bluetooth quality is by running an AOSP ROM.
That itself isn't a bad thing because I love AOSP, but its a weird occurrence.

Google Music and sound quality on BT...

Hi,
Coming from gnex... so I'm used to stock android ROMs...
So I flashed CM10 and another ASOP ROM onto the gs3... Having two issues...
1) I found that Google Music does not start playing when I connect to bluetooth with my car stereo... even if I press the button on the bluetooth.. I have to start Music manually.
2) The music quality is horrible... there's no bass at all... something is really wrong here... even playing with EQ it does not do anything... sound is very hollow... flat....
I never had these problems with my gnex and stock android roms... even the stock touchwiz for the gs3 from bell it was fine...
Anyone has any ideas?? I really don't want to put touchwiz roms on... If there's no workaround... I think I'm gonna get a nexus4.....
thanks!

This seems to be a common problem with Jelly Bean roms. My phone does the same thing. There are threads in the forums with temporary fixes, but I would say stick it out for another couple days until 4.2 becomes available to us from the developers. PLEASE don't go back to TouchWiz :crying: the nightmares.
-Brandon

I just hope 4.2 comes out soon... I miss my gnex....

Not sure if you're experiencing this issue I'm about to tell you about, or something else.
But a release or two ago (not sure if it's fixed yet), the bass was "broken" for bluetooth on CyanogenMOD/AOSP.
Everyone who updated their CM10 started to experience a loss of bass when using bluetooth.
Prior to that it had been fine.
If it hasn't been fixed yet, I'm sure it will be soon. There is a "workaround fix" listed in the CM10 thread.
In general though, music via bluetooth is a big step down in audio quality vs. using the USB audio, which is now working in CM10.

oh ok... let check it out.
thanks!
those threads can get so long... hard to follow every post..

So it seems the workaround is to make a call beforehand...
Are there any vanilla android roms that don't have bluetooth issues for our s3?
TW roms seem to have crappy battery life...

CM10 Bluetooth Audio Stream sounds tinny

I get no bass when streaming music, only what sounds like mid and treble. I tried finding the DSP Manager app, but I'm not able to open it for some reason, unless it's been merged into the settings.

Haven't tried Bluetooth lately so I don't know if the issue was ever fixed but after starting up BT make a call and then hang up when it connects the sound will be normal after that. It was a cm10/aosp issue from long ago...
May or may not be your problem, just thought I would pass that along

This works but I'd rather not have to do it every single time I want to listen to music, especially if I just run into the store real quick then come back out to resume the stream. Right now, I just place a quick call to voicemail then end it, so tha the stream kicks in normally.
Does anyone know if they fixed this bug in any of the 10.0 nightlies after 10.0 stable? I don't much care for 10.1, if it can be avoided.

[Q] pandora keeps skipping to next song only over bluetooth

im using hellkat the 2/23/14 build (I have t-mobile galaxy s2)...its a great ROM everything seems to be working fine except for streaming pandora via bluetooth.
When i start pandora (using version 5)...the music plays fine no issues. But when I turn on BT to stream to car or any other device the music just keeps skipping to next track (skips after attempting to play the current selection for about 10 secs....i say attempting because it stays on the current track attempts to play it but i dont hear anything and neither the progress_bar for song nor timer move).
Before Hellkat I was using BeanStalk 4.4.2 and pandora was streaming fine over BT.
Things I have tried to fix this none of these worked:
1. Turning off wifi then streaming
2. Went in to bluetooth setting > 'Visibility Timeout' > set to 'never'
3. Tried un-installing pandora and reinstalling.
4. Went into recovery mode, wiped cache/ delvik cache
I believe this is not a bluetooth issue because I can stream youtube audio over BT from my phone to external speakers/laptop/car and that works fine.
Is there a fix for this issue that I just can not find or is this known 'issue'? Any suggestions for a fix?
Thanks

Same problem here. I decided to switch over to Dirty Unicorn and everything works fine. Better battery life too. Unfortunately I could not post in the developer's thread to inform them of the problem.

similar behavior from other streaming audio apps
Have similar behavior on other streaming apps:
Spotify:
as soon as BT is turned on and connection is established there is no sound from phone or device the music is being streamed to. But the track does not keep skipping to next one like in pandora...its just silence.
if i turn BT off (on other device) while the song is 'playing' seems like the song status changes to 'pause' after a minute or so and if i press play ...music resumes with sound only from the phone.
Grooveshark:
If song already playing then establishing BT connection then nothing changes sound still comes from phone.
But if BT is established already then there is no sound from phone or other device. Until you break connection then press play on another selectin then sound resumes from the phone. I did a double check to make sure the volume was not turned down.
Rdio:
If BT is already established we get 'Media Player Error for {song}'
If we turn off BT and wait there is still not sound but it eventually causes reboot once it loops through a certain number of songs.
If you start rdio with BT off (turned off on remote device) then song starts with sound from phone.
If we turn on BT while a song is playing, connection is established but sound still comes from phone. But if you try to skip to next song, get Media player error again.

Having the same issue on Samsung exhilarate and cm 11 nightlies. It worked at one point in cm 11, but I can't pinpoint when it went awry...

Did anyone find the resolution to this problem? I switched to Dirty Unicorn and it works on and off. Sometimes it even turned off my bluetooth and I would have to reboot my phone to turn it back on.

Music Player does likewise
I have been using Avatar Rom for the last year or so and as most roms, it has its issues now and again. I am currently running the latest version based on CM11 and since I can't post on the developer thread I thought I would add my 2 cents here.
I have a set of bluetooth headphones and they work just fine except for recenlty on the latest kitkat verson of Avatar rom. It connects fine to the headphones. I can even start and stop the music from playing using the headset buttons, but when I hit play, the music progress bar goes full scale and hangs there for a time after which it advances to the next track and does the same thing. During all this there is no sound from the headphones. When I disconnect bluetooth it will then, after a time, begin to play the music from the phone speaker. I restored an earlier version of Avatar and tried it and it worked fine. I think it was a later version of Jelly Bean.
At any rate, it appears there is an issue with the CM11 KitKat. It may be KitKat all together. Since I haven't the posting history to post on the developer forum I decided to do it here. There was one post from someone on the develper thread that is having the same issue. Unfortunately the Avatar developement thread has very little activity and little or none from the developer. They are, however, still updating. At least they have a week or so ago.
Edit: Since there doesn't seem to be any immediate fixes for this issue I have reverted back to an earlier version of Avatar which uses CM 3.0.101 dated Jan 25th. This is working for now with the bluetooth headphones. I'll continue to use this one until such time as the issue is resolved or I find a ROM I like better.

I'm starting to think that the problem is with KitKat and not any specific custom ROM. I recently flashed The Collective and everything is working pretty good. The con to this is that the functions like "volume wake" is not implemented in this version
I also ran a search for "bluetooth" on each of the posts regarding new and active ROMs and it seems that their are very little mentioning of any fixes to this problem. It is as if there are little testing done regarding pairing the phone's bluetooth with the car's system. I would love to have this problem address but it seems that I don't have the correct amount of post to raise up the problem in the developer's thread. I hope this post catches developer's attention regarding this matter.
At the end of the day, I still love all these developers' work because without them, the S2 would've been dead a long time ago. :good:

Same issue.
Phone= Note 3 running TW kitkat on Tmobile
Connecting device: Ca-Fi Android head unit
Thinking its a Kit Kat issue. My head unit works fine when connected to another wifi source. Pandora never starts playing music. Just skips through songs.
I try streaming from phone to headunit over blutooth and pandora on phone keeps not responding. i have done factory resets, different phone roms, dns edits, congestion mods, network tweaks. same behavior regardless.

Fixed by turning off voice over LTE

[Q] Heaphone issue 4.4

Hello Community,
I have recently updated my Note 2 from Macksrom to Carbon Rom 4.4. The upgrade is awesome, very fast, looks pretty. Just all good, till i plugged in my headphones.
Now, I am quite adept at changing the rom on my phone, done this many times, and never had this issue before. So my question to you is, is anyone else having issues with their headphones on kit kat?
Tech stuff:
When rom was installed, data, cache, and dalvik were wiped. The proper gapps was installed. I use CWM.
When playing music on my speaker, it works just fine. When i plug the headphones in it does not work unless i'm at the home screen. When I try to open an app the sound is gone, when i check notifications sound is gone, and when i lock the device, guess what sound is gone. I can do all the aforementioned tasks with out a problem when playing music through the speaker. Just can't with the headphones.
Now i have tried a few things to resolve the issue, i have uninstalled the music application, I have removed the dsps i have in place, i have rebooted the phone numerous times with headphones plugged in and out. Tried different pair of headphones, and yield same result.
So for now i've run dry, I would not want to downgrade to macks rom again. But if my headphones won't work on my device i will do so.
Any input would be helpful.
****** EDIT ****** Forgot to do this earlier, but there is a workaround for this issue. I have posted another blog on what needs to be done to get your headphones to work. Follow link below.
