[Q] Bluetooth audio stutters/skips randomly on CM11 - Nexus 7 Q&A, Help & Troubleshooting

I recently got a 2012 N7 and immediately put CM11 on it. I've tried multiple versions (currently running the latest nightly) and they all have the same issue. Sometimes the audio plays fine, sometimes it stutters every few seconds, and sometimes it only stutters once every few minutes.
I did some searching and see others had a similar issue when they upgraded to 4.2.2, but that was a long time ago. Surely these issues would be fixed by now?
A few things to note:
I'm also running CM11 on my N4 and bluetooth works fine.
All of my music is "pinned" so it's cached on the device - no streaming.
Wifi is turned off

Happening to me too but not even on bluetooth

SM-N900W8 & CM11 M12 bugs and issues :(

I have a Canadian Note 3 (SM-N900W8), it's KNOX 0x0 rooted and I have CM11 M12 installed. I have been using only the M builds since I got this phone, I didn't even set up Touchwiz when I got it, I rooted and installed Cyanogenmod out of the box.
Now, with the new CM12 builds coming out, what happened to CM11, are they going to fix the remaining issues? Or did they just bail on legacy KitKat users because I'm having TONS of problems and I don't want lollipop, it runs like absolute crap for the nightlies right now and CM11 M12 isn't much better. Bluetooth takes a couple of attempts to connect, when it does my phone runs super slow to the point it force restarts. For instance, if I'm driving around, listening to music on the car stereo, pull over some where, find a new album on Google Music, start playing that, it's all good, do this a few times, every time I use my phone it gets slower and slower until it force restarts and then bluetooth has trouble connecting again. I've tried this on a few other vehicles of different brands and aftermarket stereos and it's the same result.
Audio is all funky when bluetooth is on too, it sounds like robots for the system sounds and if bluetooth drops while it's connected the music starts playing from the phone and sounds all roboty. I always do clean flashes too and the latest Paranoid Android GAPPS every time I reflash, the ROM is fine out of the box, works flawless for the first few days but after awhile, it becomes so bad I have to backup, wipe, reflash, and start over for another few weeks.
Another issue is somewhere between M8 and M12 one of the builds corrupted my SD card, I tossed in a second new card, it was corrupted again, FutureShop won't give me another one and said my phone is breaking them so I'm SD-less right now.
There are also quite a few apps that force close, but always at random, it's never when doing the same thing over and over, for instance, I can be scrolling through G+ and it tells me settings has stopped working, wasn't even using settings, didn't even have it open, haven't clicked it since booting my phone, just randomly stops working for no reason, this also happens all the time with the Camera, it says it just stops working when I haven't even used it and then if I try to use it, it says the camera is disconnected and won't work until I reboot.
I turn my phone off every night while it's charging and turn it back on every morning so every morning it gets a fresh restart, and I have to restart my phone probably 5ish times a day, if I'm using bluetooth more then normal then there's quite a few more unintentional reboots in there as well.
The last issue, which is a known issue is NFC not working, is there a fix for this yet? I kinda miss this feature and with how flawed CM11 is getting I don't know where to turn since they always seemed to be the most stable out of everything I've tried.
Any before anyone says Temasek's CM builds, I tried it, the final for CM11, it was worse then M12, it's exactly the same as M12, but every issue happens more frequently. Also, the pull down menu (when pulling down from the top right to show toggles), the bottoms of the last row was cut off so it didn't look very appealing either, it also used WAY more battery life, I usually get a full day out of one charge, so around 18 to 20ish hours on one charge, with temaseks cm11 I had to charge my phone half way through the day, sometimes my phone would just die on me without me knowing, the battery usage was always Android System.
A new problem that just happened lastnight was Google Keyboard was deleted and only the voice search would work, but "voice search can't be reached" so I couldn't search for another keyboard app from the playstore. I also used the stock GAPPS so AOSP keyboard is replaced with Google Keyboard, I had to reflash again this morning because I couldn't figure out the keyboard thing, there wasn't even a keyboard under languages in settings so I had no options to pick which keyboard to use. When I reflashes this morning I used the Modular GAPPS to it keeps the AOSP Keyboard just in case this happens again but I'm getting really tired of only having a reliable phone for a few weeks.
So, are there any fixes for these issues?
Bluetooth taking multiple attempts to connect
Bluetooth forcing random reboots
Bluetooth making audio from device all funky and sounds like a robot
Corrupting SD cards
Random system apps stopping without me even using or opening them
Google Keyboard vanishing
Are there any stable ROMs I could try for the HLTE? Maybe one that has working NFC? I'm almost thinking of going back to stock *throws up in mouth* but I don't know what else to do with how many bugs there are and Lollipop is only getting worse with the issues.
I'm also trying to avoid Lollipop because everything is white, Note 3 is an AMOLED display, each pixel illuminates on it's own so white screens use WAY more battery life then black ones which was a feature of Temasek's CM11 that I liked, had the option in settings to make everything black like the good old days.
So guys? Really out on my luck here, not sure what the next step is, any fixes for these problems? Any other ROM's I could try? Would flashing a new recovery and reflashing CM11 M12 fix some of these issues? I'm using Xiaoli CWM v6.0.4.7(20140125). Would the fact that KNOX isn't tripped have something to do with this? I really don't understand why there aren't more posts for these issues which leads me to believe I'm one of the only ones experiencing them.
Any help or suggestions would be greatly appreciated
EDIT:
I forgot to mention that when recording audio or video, it's as if the mic gain is set on full so even the slightest sound is pure distortion, normal talking volume and it clips, I found an app that lets me choose between the mics and when I pic the external mic, it's all muffles as if something is covering it but my phone wasn't in a case while I was testing so I'm not sure what the deal is there but I can't record any decent audio with this and when I record in 4K using Cinema FV-5, all the videos turn out looking like Anaglyph 3D but all pink and green, it's really weird and I don't understand why, but 1080p at 60fps works fine.
I am on CM12 and luckily have had no issues at all. I came from KK 4.4.4 and still have the NB7 BL and modem. I tried one of the guys slim ROMs alpha builds but had issues (probably operator error) but I've tried Bluetooth, GPS, WiFi , LTE etc and everything is good. Not sure what to tell you. I do however always wipe internally and d/l all my apps again through WiFi. A bit cumbersome I know but it won't give me any residual data.

Trouble with bluetooth streaming

I'm using note 4 (5.0.1) with bose soubdlink 3. When I use Bluetooth streaming from my phone when I'm connected to the wifi there are occational stutter or pops. However if wifi is off nothing happens. Needless to say no trouble with aux cable either. I'm primarily using apps like gaana, saavn, youtube for streaming music or video. I have tried to clear cache in all those apps and bluetooth killed backgroubd apps. Change router channels. Tried almost all the solutions available I could find in the net so can anyone suggest any fix??

I'm having similar issues with my 910F, but only since updating to 5.1.1, it was fine on 5.0.1. They sound more like small glitches or skips, a few times a minute, but varies. It seems the problem is more widespread:
code_google_com/p/android/issues/detail?id=95294
Turning off wifi doesn't seem to work for me, but keeping the screen on does - that is not really an acceptable workaround though. I've read somewhere it might be some kernel sleep issue. I tried the 5.1.1. NamelessROM, which has a modified kernel and it seems better, but it still happens.
I wouldn't like to go back to 5.0.1, as the 5.1.1 is a lot snappier otherwise.
Happens to mine as well, turning off WiFi does help, however the true fix is to root and then change a line in the build. Prop file.
Which I'm hoping to do today. Let you know how it goes

Really annoying bluetooth problems on N6P

Okay so I'm gonna describe my problem as clearly as possible and will hope someone can find a fix for this.
Device: Nexus 6P
OS: Android 6.0.1 (latest vendor & security patch - June 2016)
Bluetooth devices used: Sony MDR 600BT, SOL republic tracks air, jbl synchros earphones, jbl flip 2 speaker.
1) pair earphones/speakers
2) start playing music on earphones/speakers
3) works fine on first run and when screen is off
4) when I switch on my screen to change the song the music stutters for 10 full seconds, then stuttering stops.
5) I change the song and again put screen off, works fine.
6) i put my phone in my pocket and suddenly my phone audio stops skipping??? Wtf???
7) so I change my pocket and put it in my hoodie pocket. (Nearer to earphones - maybe distance is the problem I thought)
8) audio still skips............:crying:
9) put my screen on to change song, audio starts stuttering again like crazy and then stops.
10) I request anyone here to heed this request and tell me how to workaround this problem
Currently running latest android MM 6.0.1 and no improvement .....:crying:
I don't understand one thing - top of the line flagship device and still these problems? Not getting value for my hard earned money. This is wrong.
I tried it with my iPod and it works like a charm. No stutters. No skips. Nothing.
Tried different Bluetooth headphones too in case my Sony earphones were the problem. NO IMPROVEMENT SAME PROBLEM PERSISTS.
TRIED USING IT ON ANY BLUETOOTH SPEAKER THE ABOVE THINGS KEEP HAPPENING AND I AM GETTING REALLY ANNOYED WITH THIS PHONE WHEN IT COMES TO BLUETOOTH.
I'm sorry for agonizing so much. But I hope you'll can understand my problem. And hopefully there's a fix somewhere in the world.
I am having the same issue, and my searches came up with this:

Is this a Play Music issue? I don't have these issues, but I don't use Play Music. usually stream through YouTube or something like that instead. Works on BT Headset and Sony BT head unit in my car.

I can't speak for Zapjack12345, but I notice it with PowerAmp, Pandora, Spotify, YouTube, basically any app that is pushing audio through bluetooth. Audio is fine when the screen is off, but as soon as I pick up the phone, and turn it on to check notifications, things get screwy with the audio
Strange. I just checked with Pandora, YouTube, and IheartRadio and all seem fine with screen off and turning it on, using the pulldown menu, or changing songs. I'm using a cheap set of bluetooth earbuds from Amazon (no-name brand), and am stock with the phone, not rooted (yet) and on June updates. Phone was purchased in May new from Best Buy.
Same issue for me as well. I'm specifically using Amazon and Pandora most of the time. Its very annoying. On Chroma and franco kernel.
What rom are you using? This has been a well documented CM rom issue so any rom that uses CM as a base will and has had this issue since mid-January. Stock and AOSP based roms dont have this issue (from what I've seen and tried).
I'm currently using the 6/15 nightly for OMNIrom and do not have these issues.
As a sidenote, this was also an issue with Android N Dev Preview 2.

I'm currently on Pure Nexus 5/6/16. Nothing out of the ordinary installed. Tried clearing the Bluetooth cache, as the issue I am noticing was similar to issues that the Samsung S5 was having, but there was no difference.
I am going to look to go back to stock and see what happens, but looking at what OP posted, it looks like they're on stock, and having the same issue.
I am about to throw my phone in the sea. BT seems like it's getting worse and worse with each update. Cmon Google/Huawei. Don't make me lose faith.

I had a little less issues when using the Dev Preview 3 but there was another issue that arised that I hope gets fixed.
If you're using bluetooth when driving around when you lose signal or drop/gain data connection the audio skips for a quick second. Through past testing I've done working with kernel devs on 2 phones, the issue is related to how the hotplugging works for the cores. If only one core is running when the connection drops there is an issue with how the cpu ramps up and/or turns on another core to handle the workload. I thought this regression was pretty interesting seeing as one the things they were boasting about at the Google conference was how android would fix slow downs and issues when losing/gaining network connectivity with N. Hopefully it'll be fixed before final release.

You and me both. I am on my 3rd 6P and my BT problems are still the same. If the BT problems were only effecting one particular device I could understand but my Microsoft band, BT earbuds and car all seem to disconnect continuously on a bare/stock phone.
Okay guys. I changed my ROM from Resurrection Remix to Paranoid Android and this issue has been solved. Thank you so much for all your help and answers!
Does anyone else have any updates regarding this issue? Literally wanted to throw my phone out of the window during the morning commute.

Yep, this is 100% the reason. It is a CM issue. AOSP roms like Paranoid Android and Pure Nexus don't have this issue. I love Resurrection Remix, but this is starting to bug me. I may jump to PA rom soon...

Thanks. Was about to ask this question. It is a CM issue.
I have had issues with BT dropping randomly in my car on 2 different 6P's. No rhyme or reason, and it doesn't happen often, but annoying when it does. Happened on MM and DP4 currently.
On the flip side, my audio quality went down on my S7E over BT when my smartwatch was connected. Somehow, that doesn't happen with the 6P meaning I can keep my watch on in the car, so I am happy.
Hey, I just found this thread and surprised it took me this long considering I've been having this issue since I got my phone in November.
My 64gb 6P was stock until earlier this week, when I finally rooted and flashed xposed. The issue stopped the day I rooted my phone, and I was thrilled.
After reinstalling most of my apps and getting back into my routine, the problem came back. I've tried booting my phone into safe mode several times before rooting so I'm fairly confident the issue doesn't exist because of a specific app interaction, but I can't figure out what it is to save my life. I might backup again and restore to the backup I made right after rooting to see if I can narrow down the problem.
Other than that, I am very new to this stuff and honestly just thrilled to have found other people having the same issue.
I only experience the problem while connected to my car (2015 Chevy Cruze), and not any other bluetooth device.
Let me know if you guys find/have found anything I suppose?
I kinda have up on trying to narrow down the issue. I tried PureNexus, Paranoid Android, I tried different kernels, different cases. Still kept skipping and jumping, no matter how far, or close it was to my Bluetooth device (car stereo, speakers, home audio system). I went back to stock, no root, no Xposed, pure and simple Android, and I have not had a single issue, it's beautiful.

Bluetooth Call Audio Issue

Hey everyone,
I checked the similar threads but it seems everyone else has issues while playing music. My issue is only during calls.
Very often, almost every time, I have my V20 connected to a car through Bluetooth I get a really bad stuttering during calls. It is pretty much impossible to take a call like this. Sometimes the problem will go away but most of the time I just can't take any calls through Bluetooth. This has happened on a 2012 and a 2016 Toyota Prius C.
I recently got the Jaybird X3 and I experienced the same issue. Which leads me to believe that the issue is with the phone and not the car. I have a Note 4 and I never experienced this issue.
I tried stopping the Bluetooth system app (apps?) and clearing the cache and data but the problem is still there. I mention apps because I see 2 Bluetooth apps. One says its version 7.0 and the other one version 5.30.13. It seems both are active since both have memory used in the last few hours.
I've also tried the unpairing, deleting, and pairing the phone several times and the problem persists.
To be honest the problem is really annoying to the point I've considered getting something else. It is just frustrating to not be able to take calls over BT.
Anyone else having this issue? Is it maybe just my phone? Any ideas what could it be or how to solve the issue?
Thanks
I tried the phone with a MB CLA 250 and the issue is still there.
I also noticed there is a lag on the audio both while listening to music and while playing a video. It is more noticeable when playing a video since the audio is clearly out of sync by about half to one second.
Any ideas? Anyone else experiencing this?
Or is it just me?
I can't say I've had this problem. What model v20 do you have? Are you stock or rooted (and if rooted, what ROM/kernel)?
I also have 2 system BT apps but one of mine differs from yours - 5.30.12.1
I'm using a rooted VS995 with a stock 11a rom and the NSSR 5.5 kernel.

Bluetooth issues

Having an issue with the Bluetooth on this phone. When streaming music to a stock head unit (no navigation) on a 2015 Mitsubishi Lancer, the songs speed up for about a half second, every 30-40 seconds. It's not skipping, pausing or anything like that, it's actually speeding up the temp and pitch.
An S7 Edge doesn't do this with the same head unit, but the user was not happy with the S7E.
I haven't tested with other devices (but I will shortly), because she only listens to music in the car.
Anybody else see this issue? Thanks!
Same issue here. Happens in my car, with my shower speaker, and with my portable speaker
(UE Boom 2). It is incredibly frustrating and has been an issue with my phone for a while. Really miss my note7.

have you done a factory reset?
I know my bluetooth earbuds did this sometimes. It happened after trying to skip a song.. If youre not rooted, try a factory reset or see if your phone has an update? If you are rooted. Id wipe youre phone through TWRP and reflash your rom to see if that helps.
OK, so the phone isn't rooted (and never will be) and a factory reset is completely off the table. I do believe that it is either fixed or worked around, I switched the music player to PowerAMP 3.0 Beta latest build and it seems to be completely gone.
i also have this same issue when bluetoothing to my car. i still havnt found a fix/workaround for it. had this issue with stock ROM/and now the custom ROM so hopefully a update will fix it.
I've had this issue in 2 of 3 places that I've paired up.
1) Dodge Durango - Music from any app is basically unlistenable. I get about 10 seconds of music, then a bunch of stuttering, then about 10 seconds of music.....
2) Samsung Soundbar - Same description as above, but only when more than 5 feet from the soundbar. BT should be at least 30feet good in an open room, right? Yeah, not for me.
3) Jawbone Jambox - Everythign works fine here from everywhere in my condo. Separate, rooms, no problem. Weird.
So yeah.. Not sure if it's a BT buffer thing, but I certainly can't find any settings that might make any difference.
SUCKS
Same problem here. 2017 F250 Sync 3. Before I rooted it would randomly drop the bluetooth connection. Seems a little worse now that I am rooted running the stock Rom. Thinking maybe I should try an ASOP rom?
I do not have this issue or dropped connections. I do, however, get a 3-4 lag between the sound and the mouth movement on screen. It only happens with my LG V20 and my previous phone LG Nexus 5X. Before that I had a Huawei Nexus 6P that worked perfect.

I have a 2016 F150 with Sync 3 verizon 2.2 with Android Auto and I never had bluetooth issues until I rooted my V20 with Verizon. I also was having bluetooth issues with my Android Wear watch after rooting, it would randomly disconnect and never connect again until rebooting the phone. What fixed it for me was flashing the modStock kernel, I am currently on the WETA rom and everything is perfect.

So I wiped my phone and loaded the MegaROM. It's much better. Not perfect. So I believe most of the issue are likely software. Again stock the phone had significant issues. My old V10 rooted never missed a beat on this truck.
Bluetooth can always have random problems pop up unexpectedly. Aside from the occasional glitch here and there, I havent had any major bluetooth issues on t mobile stock Rom or on WETA (which I'm currently on)
My V20 never connects to my car bluetooth automatically, and doing it manually every time is driving me insane. I'll try rooting and flashing some ROMs tonight to see if that solves the issue.
