Bluetooth sounds bad

Hey all,
I have Froyo 2.2 on my N1...anyone know why my bluetooth headset crackles and is really fuzzy sounding? Sounds like they are underwater sometime...I even tried a new bluetooth headset with same problem...any ideas? Thanks.

which FroYo ROM, and which kernel.

mine does the exact same, its not just you its probably a froyo issue.

ok so i was bored and did some tests, it seems it only happens to me when trying to send audio via bluetooth when playing a flash video, reg music and videos are no problem.

I also have same problem, but on CM 5.0.X (Android 2.1). I tried Motorola S9-HD (stereo) and Nokia HS-56W (mono). Every time connect the headset and the phone is very close (20-30 cm), the sound is fine, but as soon as the phone is to push further, the sound is choppy and stutters. And this happens on any headset.

is WiFi on or off?
WiFi and bluetooth operate on same frequency band and can cause issues.

i have wi-fi on and bluetooth on.

switch WiFi off and try.

I switched off Wi-Fi and connect Motorola S9-HD and it really workes. A will try today use more and write late about it.

Same problem here with Froyo.
I turned Wifi off and the sound problems went away.
I think is a hardware problem or design problem because I used to use the same headset (Motorola H-710) with an iPhone and never had this problem even with Wifi switched on.
Would be any way to get rid of this problem?, it really bothers me to turn off the Wifi every time I get a phone call.
Thanks

its a problem with flash, not bluetooth, adobe should fix it soon

Thank you for the suggestion I will be sure to try that tomorrow!
I have kernal 2.6.32.9-27220-g328f560 android build apa26 #1
Build number is frf50
I hear this is a test version of Froyo anyway...I don't think the real Froyo has been released yet? So maybe it will be fixed...thank you.

After two days of tests, with switched off Wi-Fi, it turned out that the problem does not disappear completely. Correctly identify the reason for failed. Since stuttering occurred on different songs (that is, perhaps, that stuttering is dependent on the bitrate), I sometimes felt that the problem with lowering the frequency of the processor in sleep mode, and it is not enough to encode mp3 and transfer data via Bluetooth.

Still bad with OTA
I got the froyo OTA for my stock N1 yesterday morning.
I can confirm that the distorted sound is present on the phone application only when wifi is turned on and you are using bluetooth. At first I thought it was only when wifi was on but not connected but it appears that you can get the distortion on a phone call whenever wifi is turned on.
All entertainment application seem to work fine with my A2DP bluetooth. Again it only seems to be bluetooth phone calls and wifi turned on. Believe me this is bad enough. This didn't happen on 2.1 and if it weren't so much hassle I'd probably go back.
Hopefully someone will come up with a workaround that will allow bluetooth calls and wifi turned on at the same time. Gees, if it weren't so basic

This just drives me nuts that Google makes major changes to parts of the OS, then doesn't think to actually TEST everything they changed. This would easily been detected if they actually tried it out. Duh.

I have the FRF91 update and all the blutooth distortions are GONE.

I updated from stock via the OTA to FRF91 and thats actually when the distortions showed up on mine? Well its good to know that there is hope but now I am wondering what possibly may be different between mine and yours?
Can anyone else tell us how their bluetooth is doing on FRF91?

Does anyone think a froyo factory data reset is worth trying?

[Q] Car hands free - problems

Hi guys,
I am having problems with car BlueTooth hands free and Samsung Galaxy S:
With Eclair 2.1 it was working flawlesly, connected automaticlay after paired, I could make phonecals, receive phonecals, no quality issue, phonebook worked fine etc... The only problem was that once I did not swithced the BT on my SGS before starting to drive, for some security reasons the car was not searching for phones while driving, so I had to turn the BT in car off and on again and then it connected well. But overal problem free...
With latest 2.2 Froyo (i9000xfjp7) and also previous Froyo distributions (i tried JPA if I remember correctly), the phone can be paired, it connects to the car but after one phonecall it looses connection and works no more. The strange thing is, the BT icon on the phone shows brackets (like when connected) and also the car shows the phone is still connected. But phonecalls cannot be made via car HF and also cannot be received through it. Only by manualy accepting or dialing on the phone. And naturally the sound goes only via the phone, no HF.
The strange thing is, when I turn off the car and leave it, the phone says it is still connected to it, which is impossible.
Any ideas?
Thank you!

That is weird... When I switch back to Eclair, it works OK, back to Froyo, no HF after one phonecall...
I dont know how to work with ROMs, I managed to find out how to flash firmwares, I even handled many problems with Odin and its moods, incomplete flashes, etc... But I dont know how to use these custom ROMs...
Anyway, i would appreciate if someone told me how to resolve it without custom ROMs, as I plan to use offical Froyo when it becomes available, but with this issue, it is useless for me, as I travel a lot...

No one else?

I'm having a related problem.
I'm getting music stream cut outs (1 sec max) when streaming bluetooth to caraudio WHILE wifi on.
If i disable wifi, bluetoothaudio works fine. I know they share range bt/wifi, but this is unacceptable. They should negotiate. Everytime wifi scans, i get cutouts. Unusable. Only workaround is disabling wifi (and thats annoying because i have to be constantly activating/disabling it everytime i enter somewhere with wifi etc.
Using Docrom xxjpo v8 with voodoo.
Anyone has some software fix that makes wifi behave better when bluetooth musictream on?

[Q] Bluetooth audio streaming problems

I've had my Nexus S for a couple of weeks now and am really enjoying it.
However, bluetooth audio streaming is proving to be a royal pain.
I am using a Motorola T505 in my car.
The symptoms are pretty consistent.
If I reboot my phone then the audio will stream over bluetooth flawlessly.
If I try to stream without rebooting the phone then it will stutter and stop randomly.
My diagnosis is that there are processes running on the phone that interfere with the bluetooth or take up memory that is needed for the streaming to work smoothly.
I have read that wifi can be a culprit, but even with this switched off I have a problem.
I know that my drive home takes me through areas with varying degrees of reception. The phone does switch from 3G to edge to gprs and there are areas where the signal is quite weak. But if this was a problem then it would have an effect whether I had rebooted the phone first or not.
I have tried installing Advanced Task Manager and using this to kill programs that are running but this does not prevent the problem. Even if I am able to get free memory up to 120mb + I still get the stuttering.
I'm determined to get to the bottom of the problem as it is just about my only issue with the phone and it is a PITA to reboot before my commute.
I am aware that there are all sorts of processes running on the phone and using system resources but I don't know what is safe to kill and what isn't.
Should I use a different task manager?
Is there a particular app which might be causing a problem?
Any ideas on how I can troubleshoot this further would be gratefully received.
I am presuming that I am not the only one who has this issue?
Thanks

I stream via bt to my car stereo without any issues all the time. What is the audio bitrate you are streaming?
Sent from my Nexus S using XDA Premium App

I stream mainly podcasts. The bit rate will be whatever the default is.
Since I first posted I have had fewer problems with stuttering. I did uninstall poweramp. That may or may not have any bearing on things.
I now find that auto connection is a bit flaky. Sometimes it will connect, other times I have to do it manually.
Overall not the best experience but very nice when it works.

I have no problems streaming audio from my Nexus S to my car's audio deck (Pioneer P7000BT) and I play anything from my music apps (pandora, slacker, etc..) to my songs in my mp3 library. If you aren't on a custom rom, perhaps trying CM7 and a good kernel could help you narrow down your problem.
My phone's setup is listed below in my sig.

Bump!!!
Brand new Nexus S owner with the EXACT same problem, it's driving me nuts.
Unless I do a reboot on the phone or sometimes just a manual disable & re-enable on the bluetooth, it will keep having 1-2 second audio drops right in the middle of playback. I have a Kenwood KDC-BT838U deck. The bluetooth connection between the deck and phone never breaks. It never disconnects or disassociates in any form as far as I can tell. It's clearly a problem with my Nexus S only because I also have an iPhone 4 and it works flawlessly all the time (just not unlimited data on that phone!)
It's really annoying that others in this thread say they don't have the issue at all. I have streamed off Youtube HD and radio stations via TuneIn Radio.
It's super annoying considering I got the unlimited data package for exactly this reason.
It's only been 4 days of having the phone so maybe I'll go try and exchange tomorrow.
Just my luck

Try disabling wifi while you streaming through bluetooth. Wifi radio can interfere with some headunits.

First thing I tried!
I've moved on to cm7.0.2 and it is still a bit flaky, although not as bad as it was.
There doesn't seem to be any pattern. Sometimes it's fine other times it's not.

Interesting, I have had a Kenwood KDC-BT945U for sometime now and have used it with many different phones. My Nexus One had a very flaky connection to it, my HTC G2 connected fine but would give me audio drop outs randomly every few minutes which was SO ANNOYING, Iphone work just fine and my Nexus S works without issue also. I had assumed it was just an issue with HTC phones. Are you currently running a custom ROM? The only time I was ever able to get my Nexus One working the way it should was to use a Sense Rom.

I upgraded to CM7 and it's as bad as ever, didn't seem to help at all.
I also went through a full exchange at the store, and the brand new one straight out of the plastic did the same thing. Must be the phone itself is all I can think of.
All I have left to try is a new kernel, I can't figure out which kernel to update to if I'm using the Mobilicity AWS Nexus S

If you are having problems with bluetooth streaming and have a task killer installed... Uninstall it...
Task killers are problem makers...
Android has a built in task killer
Good news: I just saved 500 hundred bucks on a new phone by switching to XxXViRuSXxX
(So easy, a noobie can do it)

There is still no solution to this problem. I'm assuming nobody else here is using their Nexus S for bluetooth audio streaming often?
It has persisted through 2 exchanges which leads me to believe theres a problem with the hardware itself or something.
Rooted, custom kernels, nothing fixes it.
This phone is such a piece of junk, I'm hating it more and more every day

I use my Nexus S every day to stream music over BT/A2DP to my car stereo (Kenwood Excelon KDC-X994) and it works without any issues, and it always has since I got it. I've rooted it and am using a custom kernel and radio, but left the OS at stock 2.3.4. But it also worked fine with my head unit right out of the box before I made any changes to it.
I'm sorry I don't have any suggestions or solutions for you. In my own experiences it seems like certain BT chipsets just don't work well with certain pieces of BT hardware, so maybe there's just "bad blood" (so to speak) between the BT chipset in the Nexus S and your BT car hardware...?
Sorry I don't have any ideas to offer to try and help.

I also stream music over Bluetooth, the blackberry gateway device works perfectly for me, but it requires an AUX port
Sent from my Nexus S 4G using XDA Premium App

What app are you using? I saw you mentioned podcasts and I have seen this problem on my EVO with google listen if i initiate play from the head unit to continue listening. I saw this on stock and CM7. However I have not been able to replicate it as of late. have you tried a differnt program or even just restarting BT? That is what fixed it for me back then.
Hope that helps

To the Gentlemen having problems with Bluetooth streaming. I hate asking but have you tried a different device as the bluetooth receiver if possible? A lot of the users replying are using pretty nice head units and in my experience with my Golf ive had no problems. well thats lie.. i have issues with the turn by turn navigation audio not working. It cuts the music (as it should) but the navigation audio is either non existent or extremely quiet (yes ive checked the navigation volume on the device).
But yeah long story short just wondering what other bluetooth receivers you have tried. Good luck.

I have the blackberry little gateway as well. When it connects it's great (no stuttering etc), but my phone won't always connect to it when I get in my car. Sometimes turning BT on/off will then get it to connect, but it's random. The sure-fire way to get it to connect is rebooting the phone. Not sure why that is, but very annoying. Does your NS connect to your blackberry gateway every time without fail?

I have to restart the phone each time becuase to reconnect doesn't work somehow.

i have the same problem as some other people do as well. There's no actual fix, afaik, although the gingerbread roms seemed to have fixed it for me.

You can ask in the appropriate Q&A for your ROM.

in his defense - although I could be wrong, I found that it has nothing to do with one particular rom. I had this problem on stock eclair and many of the custom froyo roms. Once I ran GB, the bluetooth was more reliable.

I'm having the same issue with stock 2.2.
I found a quicker method to fix it.
I downloaded a Bluetooth widget that toggles Bluetooth on and off - this seems to reconnect with my Jeep after the toggle:
com.curvefish.widgets.bluetoothonoff
I'm sure there are a ton of widgets out there; but, you may want to give that a try!
Thanks,
Shawn

I also ran into this as after chatting with Samsung support it turns out that the Galaxy line is set to never auto connect to any bt device even if the connection was already there.

I had trouble with disconnections from my car deck (jvc kw-xr810) when it was trying to share contacts. Once I set the phone to deny contact sharing and set up a separate phone book in the deck, it connects perfectly and never drops.
It's not a perfect solution if you want your whole address book access accessible from the car however.

I use tasker for this. I have a task setup that as soon as I turn my car off and BT disconnects, toggle BT off and back on. I noticed that as long as BT is toggled off and back on, it will connect and hold it the next time I use it.
although, I have since turned that task off because GB roms seemed to have fixed the BT issues with my car. I rarely have this problem since switching to gingerbread.

Captivate stock 2.2 intermittent bluetooth problems
I have a stock Captivate with 2.2 android and I'm using a Motorola S10-HD headset to listen to music while I'm at work.
The bluetooth will randomly disconnect causing the music to pause. Sometimes it will reconnect on it's own several seconds later and I am able to continue listening by clicking the play button on the headset. If it doesn't reconnect on it's own then I have to turn off bluetooth on the phone and turn it back on. This will cause it to reconnect but the problem may occur again.
I have switched to listening to music on my Galaxy Tab 10.1 and haven't had any problems so it must be the phone.
Is there anything that will correct the problem?
Is this a defect with my phone or just a design problem with all Captivate phones?

[FIX] Possilbe A2DP Streaming Workaround

Stuttering and skipping streaming are very known issues on many jelly bean devices.
The most times when I listen to music in my car, i do this via bluetooth. So it is really annoying me and some day, I will have an accident, while I am fumbling with my HTC One.
I replaced the audio.a2dp.default.so with one of the Nexus 4 (4.2.2) and it just worked well, but only the first time using bluetooth streaming after rebooting the device.
I changed some settings in audio.conf and it still stutters.
But then, i deactived wifi while the device was streaming and all stuttering and skipping was gone.
So... can someone just confirm, whether the a2dp streaming works correctly, when wifi is deactived?
I want to know, whether this is the only point to get this work and I don't want to change my working mess

is nobody interested in this?

I posted this bluetooth issue a while back on this forum, and the issue is corrected by switching off WIFI while using BT. Apparently the new update which is due soon fixes the issue but only one user has confirmed that so far.
Since I use bluetooth streaming on the car mainly, I use Tasker so that when Bluetooth connects, it automatically switches WIFI off (don't need WIFI while driving and saves battery), and when it disconnects it switches it back on. This way the phone just works seamlessly.

Just turning the wifi off and back on again when I connect bluetooth seems to solve this issue for me.

i can confirm - turning wifi on/off fixes it as well for me (until next time I go bluetooth)

I discovered this a couple of weeks ago too. I was about to send it back too. Cant live without podcasts and audible in the car!

I have the problem that i cant even here any sound on my HTC CAR A100 Car Stereo Clip, even if wlan is deactivated With my old sensation everything is okey..

I wonder if this also improves the bitpool value. I'm noticing on my HTC One that bluetooth streaming quality is not very good. From what I've read it has to do with a bitpool value that it set too low, increasing this value is supposed to increase the streaming quality. Highs sound distorted on my phone over BT I can't believe Google/HTC have not addressed this issue.

I have not been able to solve the bluetooth audio streaming issue by turning off WiFi for my car. It works perfectly fine with my Jambox even with WiFi turned on, but in the car, it does not work either way and I'm using software version 1.29.401.13

Did you manage to fix the problem with the A100 as mine is exactly the same, works fine on my Sensation but no the HTC One.

have the same problem:
If wifi is ON and bluetooth is ON, eg at streaming youtube over the bluetooth headset, it stutters and has distortions.
If wifi is OFF and stream a video from the sdcard over bluetooth all is fine.
what i find out:
I use the JellyBean from Quarkx for defy.
The build from 7.3.2013 worked
All later builds, with the new wifi driver had this problem.
But its a known bug that JellyBean has a2dp issues, i guess.
This trick, to change audio.a2dp doesnt helped me

I didn't noticed any problem with my phone even when the wifi ON, I'm using the latest radio "4A.16.3250.24_10.38.1150.03L" found in this post: http://forum.xda-developers.com/showthread.php?t=2245615
I don't know if it can help..
