Problem with bluetooth headphones - JASJAR, XDA Exec, MDA Pro General

Hello, with my qtek 9000, from time to time I hear the music only half of the time (0,5s I hear, 0,5 not, and actually the uni adapt to this (the music is x2 longer)) with my ety8, and it doesn't come from thoses since I have no problem with them on another mobile and I get the same problem with other bluetooth headphones on my uni.
It doesn't come from being indoor/outdoor, near wifi or not because it's sometime doing this problem in my house and sometime not outdoor.
Soft reset does nothing, reset bluetooth on uni and my headphones once worked but it was certainlty pure chance because I tried many times then and it didn't do anything.
I hard reseted with another rom and the problem stayed the same.
Did anyone ever had this problem ? It's really wierd because when it's working, there is absolutely no problem so I can't really think that it would come from a damaged bluetooth transmitter...

try looking in Advanced Settings and change the bps transmitted etc. a fairly unnoticable lowering in quality of sound should improve the juddering.

well, reduced to 21 I still have a little pause each 5 seconds, reduced to 20 it's fine but the difference of quality is clearly noticeable.

my settings are:
Use Joint Stereo: Yes
Bitpool: 30
Max supported bitpool: 30
Min supported bitpool: 30
Sample rate: 48000 Hz
BtA2dpSnd Priority256: 0
Hope this helps

I don't have "BtA2dpSnd Priority256", though I don't think it would change anything, I'm gonna stay with this, that was a good hotfix thanks.

Wow, now, in only some days and for no reasons apparently, I must reduce it to 11.
Long time ago I let my uni just near to a wifi antena (from my freebox), actually touching it, bluetooth on but not using it at this time. Since my micro-weave detector make noise just around thoses antenas when I approach it, do you think it can have something to do with that ?

A2DP - sound cutting out

I have been listening to music for the last 30 mins or so. I am using my Anycomm stereo BT headphones and the new ROM, but quite annoyingly with my wizzard only 50 cm or so away from me, it keeps cutting out the sound. I wondered if it was anything to do with lack of memory or other programs running and using cpu so I stopped all other relevant programs, but it is still doing it.
anyone else having these probs?
PvH
I noticed same problem it looks that wizard have very weak anthena for bluetooth it looks to be worse than class b specification for that. At first i thought that it's problem of my headset but it happens for me on other ones too.

A2DP pitch changes, Wizard or Jabra BT620s?

Given the extensive posting about A2DP on the Wizard, I was a little bit surprised not to find anything about this problem:
When streaming music from windows media player, the sound sometimes starts playing back slower or faster - thus changing the pitch. Sometimes as much as a step and a half (like from C to A). Clearly noticable in other words.
Now is this because of the Wizard, or the Jabra BT620s? I googled, and I found one other person complaining about something similar - but when using an iPod.
With default settings, I was getting drop-outs every 2 or three minutes...
I was able to tweak reg settings some:
A2DP\Settings\BitPool = 45 (60 sounds great, but only for a few seconds)
Drivers\BuiltIn\BtA2dpSnd\Priority256 = 60
AudioGateway\Capability = 69
I use Shogunmark's Cingular based 2.26.10.2 ROM.
Any thoughts?
Hey I'm getting the same effect with my NextLink Spider stereo bluetooth set...
Something tells me its just the processor speeding up and down, or something with the transfer to the headsets and codecs. I wanted to check whether it was VBR music files (variable bit rate) that were doing it, but since that usually only affects quality I don't think it is related.
Its obviously not a big deal, it can be kinda funny sometimes =P ... but I am curious as to why its doing that and if it can be corrected !
So basically I'm just lettin ya know you're not alone with the ipod guy!
(I have a cingular 8125, and I just switched over to a tmobile MDA (8125 is waaay to bulky), so i'll let you know if the new phone does it too!)
Good to know it also happens on the MS BT stack. This is a common problem with pre-WM5 Widcomm-based devices (see my A2DP-related articles).
Ok, so I'm not alone... Funny how that makes me feel better.
I'm still looking for a solution to all this. I guess if this is because of bandwidth limitations, it would make sense to lower the BitPool setting.
I'm going to try to dial in the best settings, by trial and error...
I sure hope MS can improve the BT stack some more.
this is to do with the buffer,when the muisic stops because of interference the wizard carryon sending the muisic to the buffer,problem is the when the interference stops the muisic track is seconds ahead of the buffer ,so the muisic is rushed out in order to receive new data.this seems to be a problem with the proccessing units in the headphone and not in the ppc itself.this also happens in aku3 roms.
yup i got the same prob... i took it that it was the headset and not the xda, the slowing down i thought was it thinking hmm im running out of music so ill slow down until i get some more so this guy can still hear something damm anoying im finding the whole bluetooth thing not worth the hastle.
All i want to be able to do now is get talk button on the wired headphones to start up the voice dial and then i can have what i want just with a wire.

Hmm, yeah that was my thought as well. It reminds me of old tape based Walkmans with bad batteries.
Does anyone know the equation behind the BitPool registry entry? At 30 vs 45, the sound quality is pretty bad, but with less pitch changes and / or dropouts. At 60 the sound is fantastic for a few seconds before the problems start. It appears that even increments of 15 (i.e. 30, 45, 60) at the time works better than numbers like 34 or 42 - it results in more conversion artifacts. I assume the BitPool settings determine Bit resolution and Sample rate...
Right now, I'm listening to internet radio at 64Kbps with no problems. So as far as I can tell the lower bit rate sources work better. Maybe also fixed bit rate over VBR.
Oh, and what is the AudioGateway\Capability number for?
With my current settings 128Kbps files play fine, but 160Kbps files do pitch change thing...

8525 with wm6, bluetooth suddenly bad

Forgot I'm a member here...
Hay guys. I updated my 8525 to WM6 around Thanksgiving, and everything was great. I had no problems at all. I decided to whip out my old i-phono stereo bluetooth headset and try it out with the superior A2DP quality on WM6. It worked really well, though I decided to go ahead and remove the BitPool and MaxSupportedBitPool registry keys as well as most people suggest for increased quality. It worked really well up until yesturday when I tried using my headset, and everything went wrong. When the headset syncs with the phone, the phone starts facing a lot of slow down. The worst thing is that when I try to play music, the music stutters hella bad, and the quality is very low. It's almost like the phone is super busy type of poor playback, which can happen even without using bluetooth, though the pronlem is exasgerbated when trying to stream music data to the headset.
Short of a hard reset, I haven't a clue what to do, or why it is doing it all of a sudden. I've already tried the task manager fix, and related .cab fix, but it did nothing for me. Really ticks me off....
None of the genius minds here has an answer?

MP3 Audio Glitch(pause)

Has anyone been able to find a fix for the glitch(pause) every 5 or so minutes when playing Audio through headphones.
It even does it in flight mode, ive turned Activesync off, but it still does the glitch.
Thanks.
Dear Sir,
I think that I have the same problem, sometimes mp3 player(audio manager) pause for 1/10 of second.
I do some HR, because I suppose that's a software bugs, but I don't have solved the problem with HR.
Best regards
This is a well known issue, I think it's like this on every niki device.

Aye, 'tis a shame.
At times I wonder if its slightly related to video drivers - I always use the Niki with my A2DP Jabras down the gym, and will switch the screen off to save a bit of juice - music playback stops for a moment when the screen blanks.
Still, thats not as irritating as the SMS notifications coming through loud and clear on the bluetooth headset. Ouch!

Does everyone have awful Bluetooth connection or is it just mine?

So I purchased some new JBL headphones black Friday. They work perfectly with everything but my Essential phone. Basically the audio cuts in and out less the 12" away. I listen to a lot of music and this is complete BS! Bluetooth in my car is sometimes sketchy and also on my Bose SoundLink Mini.
Do all of you have connection issues? Is it a firmware issue? I'm still on stock 7.1.1 with latest security patch.
P.S. All this happens on my wife's white one as wellwith same everything.
I have the same issue with multiple bluetooth audio devices on mine. Someone suggested turning off Bluetooth scanning in the location portion of the system settings but that did not fix it for me.
I'm on the Oreo beta.
The one thing turning off scanning DID fix for me in terms of Bluetooth issues was the constant disconnects I was seeing to my smart watch. That's stable now.
No issues with BT on my PH-1 with the numerous BT headphones i've used it with.
Currently using a Bose Soundlink OE and no complaints whatsoever.
Tried all Roms, stock and Oreo and BT audio is fine on my end.
After messing with the Bluetooth settings, I removed all devices and rebooted the phone as well. I paired the JBL and sure enough they work fine with no audio dropping. So I'm wondering if something is going on when I first initially pair the devices. I'm not a radio engineer, so I'm only guessing. It seems like it's not getting full handshake with the devices I first pair with. Only after I forget the device, reboot, the pair again will it have a good grip on the device.

I got a red OnePlus 5T and white Essential at the same time and on looks alone used the essential. I've had two black models previous to this. I went to the gym after syncing my BT headphones and the result was music that but out every .5 seconds. Needless to say, I wanted to kill myself. I tried deleting all devices, resyncing, restarting, nada. I immediately went to the OnePlus with no issues. The essential is such a good value proposition especially with regards to build quality but I'm running out of reasons to keep trying it, price aside.

I totally get that. I haven't had the Bluetooth issues any more. Unfortunately now it will randomly freeze up. So, I am actually thinking of selling mine and getting a OnePlus 5t.
Just want to add that i have my essential phone since Dec. Never had any Bluetooth issues.
I've also got the same problem, can't connect to my PC, my pebble does connect but I have to "forget device", rescan and repair it everytime I connect. It's very temperamental with my Bluetooth headset too
with the beta versions of the os under developer options you now see options for different bluetooth codecs including aptx. I believe it is still a grey area if essential has acquired the rights to include the aptx codec but if you are rooted you can sideload the aptx directly. See here for more info on aptx https://forum.xda-developers.com/showthread.php?t=2531440
Hope it helps you out.
Personally ive experienced no bluetooth issues using stenheiser hd-1 in ear headphones, bluetooth stereos and car adapters.
I'm having the same issue with my Essential phone and all bluetooth audio playback devices. If the phone is more than a foot away, it gets choppy. I don't have a workaround yet but will try some of the suggestions here.

The Bluetooth connectivity is not that great. I don't quite have the exact problem you describe, but range is pretty poor. For example, my Gear S3 Classic is about 6-7 meters away from me right now and I cannot connect to it via Bluetooth. I have to be closer. My Samsung S8+ (after some post-launch patches of course) could maintain the connection to about 10 meters away. My S7 easily did 15 meter radius. This is all comparison in the same physical space.
my BT stutters about once every 45 seconds or so, also in my 2011 Mazda 3, the names of the songs do not display up on the screen where they had with every other phone i have had paired.
BTW if you are thinking of buying a 2009-13 Mazda3 there is a 5 second BT audio delay while watching Youtube/ videos ... and it gets really annoying

Latency like that is perceptible on almost all phones and receivers... Your car is not special in that way...
Wanna see some really bad latency... Try playing a game on an emulator while using a Chromecast to your TV...
Here is a perfect example of how bad it is. I did a little test with my bluetooth speaker(it's nothing special, just an average bluetooth speaker, a few years old so not the latest bluetooth tech.)
I set the phone on the kitchen counter, connected and playing music on my speaker which is right next to it. I pick up the speaker and hold it to my chest, while I'm leaning against the counter, then turn around so my body is between the phone and speaker, it quits working. I spin back around, it works... As a comparison, i dug the old S6 out of a drawer, and it can play on the speaker with me holding the speaker the same way, spin around, and walk to the other end of my kitchen which is about 16ft and it keeps playing the whole time.
Same issue with bluetooth headphones, which led me to this awful issue. I'm a cyclist, and with the phone in my back pocket of my jersey, the headphones won't work.
Frustrated, today I unlocked and flashed back to the oldest stock software I could find... still doesn't work.
Same issue here. Is there a fix for this?
The only device I get a solid connection with is my Jabra Elite 65t headset (which happens to be BT 5.0 like the phone is). My Samsung gear and both of my cars have horrible connections. I believe there is a memory leak in the bluetooth stack because It'll get worse and worse, then I can clear it up temporarily by turning off bluetooth for about 30 seconds to 1 minute then turning it on again... then it'll tend to last until I reconnect again later.

If you are on 8.1 you can go into developer area and there are settings for BT connection type. You may be able.to get better results by changing from the default which is best effort to one that prioritizes connection quality. There are other settings as well. I haven't played with the settings because I'm not seeing issues.
Fixed mine
Disabled hd audio:aac in bluetooth device settings(for each headphones or device with that issue) and drop outs stopped i had them every 40sec for .5.
I have 4 different Bluetooth devices that all work perfect and all have 10+ meter range. I'm on the AICP rom and no problems at all.
