[Q] Music and bluetooth headset problem

Hello folks
I have tested these roms Leedroid 3.1.1 and Revolution hd 5.1.8
Sound lag when listening to music(Bluetooth Headset) Can anyone fix this problem.

Can you describe the lag better? What kind of headset?

I have this problem too...i have SE MW600 bluetooth headset....problem is signal noise in hight frequenties.with wired headset is no lag.i have this problem only with sense's ROM. cyanogen mod is without this problem.

Hi,
I don't know if my problem is the same.... perhaps due to language.
My problem is that every 3-4 minutes listening to music, sound pauses for 1-2 seconds, and then it resumes music for 3-4 minutes to next pause and so on...
I have the problem with a Cardo / Schuberth SRC System bluetooth handsfree.
I tried several Sense ROMs and I found always this problem, but with CM7 it works correctly.
I tried to compile the kernel by using CM7 bluetooth options, but no succeed.
I tried by compiling the kernel by overwritting all bluetooth source code related (using CM7 kernel code). I get an error, and once solved by merging code, the problem is still there.
I tried by overwritting all bluetooth related libraries, but the ROM is not starting.
If anyone has any idea on how follow...
THANKS!

This is a known issue with Gingerbread. I actually am surprised there's not more chatter in the XDA DHD forums about it. Google updated the Bluetooth stack in Gingerbread, which breaks compatibility with many Bluetooth audio devices, like headsets and car stereos. While some people claim that updating the Bluetooth stack on your headset/stereo should fix the problem, it's not always possible. In fact, it's rarely possible, as most of the manufacturers aren't going to bother with firmware upgrades for those of us with Gingerbread devices yet.
I haven't tried CM7 myself, as I'd much rather keep Sense, but I think Jorgitosms's on the right track. Not being much of a developer, I'm not at all sure how to go about doing this, but what about pulling the Bluetooth stack out of a Froyo Sense ROM and putting it into a Gingerbread one? I love everything about Gingerbread, except the broken A2DP audio, so I've gone back to Froyo. If we could get this done, I think a lot of people would be relieved.

I initially thought it was my bt headphones (nokia 905i) creating this skipping but today i exhumed my old htc hd and the music played skip free via bluetooth.
@craig0r, Ive had this skipping on Froyo as well so Im not sure, maybe I have a dud Desire HD. Mind you Im still on stock gingerbread rom. downgrading and rooting seems just too complicated, not too mention which rom to choose!

Any JB Roms have working BT Handsfree?

Hello all,
Like the title says, do any of the current JB 4.1 ROMS have working bluetooth for phone calls?
I'm currently on SlimBean, and bluetooth will pair with my car, but there is no audio. I can't hear the caller, and they can't hear me. There is some magic happening, because my car will tell me when the call connects and when I hang up.
It did work with LiteRom, so I know BT works in the car, but I am loving the battery life/features of the JB roms. Anybody have suggestions? I suppose I could install every current JB ROM and test, but would like to ask the community before going through that hassle.
Thanks,

I'm on dman's cm10 and my bt headphones work well for calls/music and the music controls (play/pause/skip) all work as well.

Appreciate the feedback, unfortunately CM10 didn't work for me either. I ended up loading CM10, CAMP, PAC and SlimBean, none of them had audio on my cars bluetooth. Like I said, it's very close to working. The display in my car will show the number I am dialing or the incoming number, it connects, just no audio at all. I went back to LiteROM and it works as normal. It's a bit of a bummer too, I was really please with AOSP/CM based ROMs, and the battery life was fantastic. Guess I'll have to wait for a few more bugs to get worked out.
By the way, the vehicle is a 2012 Chevrolet, so I would hope that its JB compatible.
Thanks.

Slim had bluetooth working for me, but it took a couple times to pair to my car. You try a full wipe before flashing?

That I did. Old habit of mine, I don't dirty flash anything unless it's an update of the same ROM. Googling the issue seems to show mixed results for JB ROMs based on what kind of device you're pairing with. I have a feeling it's just an issue with BT not being 100%. I can wait patiently while the devs do their magic, just have to stick with ICS until then (have to have the handsfree for driving).
Thumbs up to the devs in this section by the way. My personal phone is an HTC One X. When running CM10 on the Glide, it's easily as fast as my one X.

Best Bluetooth on non-TW ROM?

I have tried several, including:
Both paranoid android roms
Carbon
AOKP
xone
Liquid smooth
The bluetooth "works", but it takes a lot of fiddling with. Which is fine at times. I am looking for a non touchwiz ROM though that the Bluetooth works better on.
Most of the above I have to dial using the phone because voice dial isn't recognizing a voice or the buttons on my headset/car are not working.
Couple of the above voice works OK but if I listen to music it dorks it up and I have to resync before I can use the phone.
Yes, I am sure it has been asked in some form before and I'm sorry but I could fine any real answers and it has been awhile since it was asked.
Any help or pointing me in the right direction would be most appreciated.

The latest vanilla rootbox works best for me. I use multiple bluetooth devices every day and am constantly switching between the two in my car (one for audio, one for phone), headphones, and a headset, and listening to music and talking on the phone, and I have had the least problems with that rom out of all the non-TW. I think there is a setting to tell the phone to use a bluetooth device for voice commands, but I forget where it is and I don't know if it works (although that may be a TW setting, I forget that too).

BLUETOOTH issues CM12, CM13 and other ROMs N7100

hi. I have done so many tests so far so I know what I'm saying.
most used ROMs for N7100 are heavly unstable with bluetooth.
effects are various, from stuttering in a2dp with BT headset to bad reconnecting to low power devices (example smartbands) etc.
again, to connect to some special device I need to reboot many times, for example some kind of internet things.
at the moment the ONLY rom, beside stock, that has a PERFECT manage of bluetooth is:
[OK] ---- [ROM][5.1.1][Haxynox] AOSP for n7100
and roms I tested that has not:
[NOT] ---- [ROM][5.1.1] 12.11.2015 Cyanogenmod 12.1 N7100
[NOT] ---- [ROM][6.0.1] Cyanogenmod 13.0 N7100 Build 8
[NOT] ---- Paranoid Android for Note II(GT-N7100)
[NOT] ---- [ROM][5.1.1_r24][Official][Nightlies]Exodus Android for Samsung note II
[NOT] ---- [ROM][5.1.1][Lollipop][Official][Nightlies] NamelessROM 2.1
[NOT] ---- [ROM] CyanoBiz - CM-13.0 - Doze enable - n7100 / Galaxy Notes2
[continue]
how to test:
there are many methods to test bad handling of bluetooth, most important test with daily use, but to prevent headache you can do in this way.
- pair any bluetooth headset or car free-hand kit.
- play some music to that device
- meantime go to bluetooth option and search for new devices
- if music stutters that rom is affected with bt issues, if not rom will never hurt you and your devices.
so: why I don't stay with Haxynox?
I would but that rom is
a little unstable.
vivavoice volume doesn't work.
bt file transfer crashes.
sometime reboots.
doesn't handle >16GB sd card.
doesn't handle movetosd.
developer is working on CM13 and left this.
please feedback here to have stable bluetooth back!

On RR Lollipop I've had bt stuttering
on dr.ketan kitkat bt was very good
on CM 13 build 7 bt works just fine: tested on mazda infotainment, bt jack adapter, JBL speaker, laptop, pairing with other phone also ok and recently with SmartWatch 3, so I think it's related to hardware if you can't get it to work

thank you for reply. sorry but I don't think is hardware related.
I read tons of thread where n7100 owners wait for a build with decent bluetooth manager. most are still searching for. I was lucky as I found at least haynox build.
so I decided to share this.
did you test playing music through bt speakers and while listen music going to 'searching for bt device' screen?

no, I think when it's paired with device and sound plays well, so there is no need to go there, but I#ll check it this evening

thank you. this may be useful for me.

tested:
[ROM][5.1.1_r24][Official][Nightlies]Exodus Android for Samsung note II
[ROM][5.1.1][Lollipop][Official][Nightlies] NamelessROM 2.1
both have bt issues

yep, I had to go back to stock.. my sony smartwatch 3 was unusable.... I don't like to put my money on trash...

[ROM][5.1.1] 12.11.2015 Cyanogenmod 12.1 N7100
[ROM][6.0.1] Cyanogenmod 13.0 N7100 Build 8
Have problems with bluetooth calls (Static, robot voice), Music player is fine

As I added more bt devices it started to stutter rarely. I noticed that it only stutters when bt is searching, although it's connected.
CM13 build 7.
I believe it's related to data flow, it just can't send/receive that much data simultaneously

ok, after tried so many roms I can say that if you have that stutter bluetooth is less stabile than ideal. can be that you have devices where is less evident. but it's not the way to be:
if you can nandroid backup your note2 and try haynox build. you'll nave stable BT and in test never stutters. in fact there's no way to make it stutter with this ROM. but as said there are other issues..
less than ideal.

[ROM] CyanoBiz - CM-13.0 - Doze enable - n7100 / Galaxy Notes2
my hope for BT was fix by P.A.N. from i9305 github, but NO, it doesn't work well.
waiting for AOSP from same developer

Any news about this?
CM Roms were always weak about bluetooth stream. I have a 6p now and it's happening. On Pure Nexus I'm fine but would love to stay CM

after many devices and settings I came into conclusion, that bluetooth problem is related to android wear app. When I had paired SW3 and allowed Note2 to constantly search for my watch it stutters often, but after uninstalling all that crap, Note don't search for other devices when connected to 1 device and sound doesn't stutter, not even once.
I'm using CM13 build 10

Umm I posted some stuff in Ivan's build 10 rom thread. If you switch network to 2G instead of 3G, bluetooth calling works once again. I tested this about 20 times afterwards and it worked everytime. It even works with traffalguar square's rom.
Hope it helps.

[ROM][6.0.1][v6.18][Beanstalk][OFFICIAL][Great Experience][DU-Features][19.06.16]
This rom have bt issue too.
Still no solution ?

I found a good ROM
I've been struggling with BT Handsfree issue for a very long time. I almost bought a new phone recently, because of this issue. I drive a lot and I really need that function. Samsung original stock rom is so bloated and ugly that it was not an option. Unfortunately non of the CM and AOSP ROMS have fully working BT audio.
I found a solution: [ROM][GT-N7100][TW 4.4.4] Eclipse By AC version 9
It is a stock based ROM with TouchWiz UI. I don't like Samsung interface but this one is really debloated and very pleasant. I think I will get used to it. It's super stable and very fast. I moved to it a few days ago, and my Plantronics M70 headset is finally working like a charm. Just remember to make a full phone wipe before install (including data partition). I had some issues with that.

Bluetooth Range Issues

Hello,
I can't get a good range with bluetooth on cyanogenmod 13 ROMS. I get good bluetooth audio if i lay my phone on the headphones but as soon as the phone is 12 inchs away. The music cuts out and disconnects the pairing. On my old touchwiz based rom, this was not a problem.
Does anyone have any insight of why a cyanogenmod rom decreases bluetooth distance?
Thanks

I had that same issue when I installed BlissRom. I believe @lilferraro and @SaintZ93 are working on a fix!
