Audio lag with Bluetooth Headset - Nexus 7 Q&A, Help & Troubleshooting

I have a terrible problem. I'm proud owner of some Sennheiser MM550-X Bluetooth earphones/headphone and have problems while watching movies from internal memory and external sources like streaming youtube or from my NAS.
The audio has a terrible delay of something around 1-2 seconds.
Makes me wondering. I thought nearly every device supports apt-x for Bluetooth audio... Seems like aosp based devices didn't.
I google a little bit around and seeing hundreds of posts from people having the same problem. It seems to be a known issue since ICS but it is still present in JB. Google didn't fix it.
The problems seems to be caused by the integrated chip which handles wifi and Bluetooth together. If both is enabled the delay is much higher... It also effects games and system sounds like the tick sound from keyboard etc.
It also looks like some devs found possible fixes for that. Think I saw a post on transformer Prime forums from team eos who might have fixed that.
Is it possible for anyone to fix this problem. Are there any Bluetooth drivers to play around with?
I also noticed the same issue on my HTC One X which is also tegra3 powered but it is not so hard like on nexus 7. On iPod and ipad I have no delay issues, which proves that this is an android bug.
For anyone with the same problems I found out that dice player from play store fixes that issue for me for watching videos. It also have the option to adjust the audio delay manually. But this is only for watching movies... The system sound delay still persists.
Thanks and regards from berlin

AOSP roms simply don't support APT-X. you need to use a stock rom on a phone that supports it (one-x, gsIII, note 2, etc)
So the problem is - you're not getting apt-x.

Stutters in audio playback every few minutes

I am playing some music recorded to .ogg, using either Pocket Player or Coreplayer, but every few minutes (about 4-5 minutes), there is a little stutter during playback. It is very annoying and destroys my enjoyment.
I agree that the tracks are long (around 20 minutes) and the files are therefore large, but I have tried to increase buffer size for the players, but it seems to make no difference.
Has anyone got some inspiration for me?
thanks

I've also noticed similar minor "glitches" in the audio playback, but when playing .M4A files (similar to AAC).
Anyone else noticed this? I don't know if it also affects MP3s.
Ideas, anyone ?
- Steve
Hi,
I am also facing this problem any resolution?
Yes.... this problem happens with Mp3 also.... who could think of it. It can't even play music without stammering... lets not get started on video
BANE
I have tried the basic guide to enhancing performance at
http://forum.xda-developers.com/showthread.php?t=446366
and it seems to make no difference - the stutters are still there. I thought it might be related to doing a Send/receive in Messenger, but it doesn't seem to be.
This is real downer on my experience of the HD, as I was expecting it to be the ultimate communication/entertainment all-in-one device. Not so sure now.
rjstep3
I don't think optimizing performance has anything to do with this. I mean, playing audio is NOT a demanding process. My old xda2i used to play audio without hassle....
There is something else that is responsible for this skipping in audio on the HD, I just can't figure out WHAT.
BANE
Same for me with MP3 using PocketMusic player, hopefully will get some updates soon... Then hopefully the HD will be more of what we all wanted!
Excuse me if this is stating the obvious, but I would urge everyone experiencing this problem to be sure to REPORT IT to HTC.
If there is no obvious solution and it requires attention from HTC developers, then we can't expect them to fix it unless people actually tell them about it, preferably quite a few people !
Thanks,
- Steve
I have to say that I haven't experienced this even once. And I should be seeing it more than anyone, because I listen to audio books on my Touch HD for a total of about 80 minutes every day during my commute. My files are MP3s that are up to 8 hours long (100+ MB in some cases). I use Pocket Player 3.7. Never happened to me even once so far.
That stutter was exactly what was happening to me on my previous Windows Mobile phone, the AT&T Tilt (HTC TyTN II). It was like a half-second pause (not a skip) every once in a while. I was seeing it with Pocket Player 3.7 and with Audible.com's own player (possibly using the libraries of Windows Media Player) on that device.
In fact, one of the things that I like best about my Touch HD is that it cured that occasional pause problem for me when listening to audio books.

Interesting.. It would probably be less noticable with speech, though.
In my case, it's more like an occasional discontinuity in the tempo of the music, perhaps like a tiny fragment has been skipped. I only notice it every few minutes, but then again because the sound quality is generally very good, it's an annoying artifact in an otherwise pleasant listening experience.
I'm using the same music files that played back OK on my old PDA, so it can't be the fault of the files. I've not got any other fancy software loaded that might upset it, either.

That's probably true. There are more silences between sentences and, sometimes, words. That increases the likelihood that the stutter might coincide with one of those, which reduces my likelihood of noticing it. On the other hand, what are the odds of it always having coincided with those occasional brief silences in the audio book, in my entire two weeks' worth of audio book listening (easily over 10 hours) since I got the Touch HD?... I've never noticed it even once, while my similar stuttering experience on my Tilt was fairly obvious and annoying on a regular basis.
I have the same problem in all music players. It IS annoying. I have read in the Touch Diamond forum that they have had the same issue from day one. My Prophet and Trinity never had this skipping issue. Maybe a future rom will fix it.
Interesting thread here.. havent noticed anything so far on my HD..
testing it now to see if it accures!
will tell you the results in a bit
After aprox. 20mins of mp3s all is smooth without problems!
Guys i dont know why you have this annoying glitches.. i have no problems with mp3s or what so ever.. (using TF3D player)
the sound quality from the HD to my Creative Aurvana is just superb! i cant see why some people complain about the sound quality!
(get a decent pair of headphones maybe?)
here are is the info of my HD:
ROM: 1.14.40.1.3 (22273) WWE
ROM date: 10/24/08
Radio: 1.09.25.14
FYI as we all do.. i added a lot of programs and tweaks to the device so its not "clean"
as it was out of the box!
hope you resolve this issue.. but my guess its just a small bug in some rom builds?
yes this is a bug, and a bad bug too, it makes listening to any track really irksome. It has that sort of effect, where you sit there just waiting for the track to stutter.
the funny thing is that the stutters occur between 4-5 minutes apart. There must be something to that, the processor must become occupied at these regular intervals.
I think the obvious point, as someone pointed out above, is to report it to HTC - what they will do I have no idea, they normally don't answer my bug reports other than a formal receipt.
It seems from the posts here that this is definitely a problem. Perhaps another class action to make some action? The HD is now useless to me as a media player ...

I have the same problem too, I thought I was the only one.
I will try a hard reset and play some audio files to check if it is related to some piece of software installed on my HD.

Crackling and popping sound

So I've had my N7 about a week and its almost perfect. The only real problem I'm having is sound. Whenever I'm playing music locally or streaming from Google play, ill get ungodly popping and skips in music playback. It only happens when I'm multitasking, so I know its not a general hardware fault.
I'm currently using paranoid android, latest version. I've tried different kernels, governers and schedulers but nothing seems to fix the issue. Tried disabling DSP Manager and wiping/restoring. It's hard to see how the device can get overstressed while playing music. My Galaxy nexus doesn't have this problem, and its not as powerful.
I've tried researching the issue, but all I've been able to find are complaints about the speaker. I'm not using speaker and have tried several pairs of headphones.
Anybody got any ideas on how to fix this?

Choppy Video via browser(s) and Video apps...

I have the Verizon Note 3 and whenever I try to play a video from an internet site such as a news clip etc...it is all choppy and lags. This happens no matter what browser I use (Chrome or Stock) and does the same thing when using MX Player or the built-in video player. Not sure what's going on. I originally had the power save mode enabled and thought that may be causing it, but I turned it off, rebooted and video still lags. I had no issues with my Nexus 7 playing embedded videos so I am not sure what's going on. This phone has powerful hardware so I have to believe it's something software related?? Wanted to add this is happening while using wifi or 4G, doesn't seem to matter.
Any input?

There are 2 things you can do to improve video playback on your Note 3:
1. Install MX Player, go to its settings and download the NeoN.zip driver. After you install that (unzip first) and put video and audio playback on HW+ (also in the MX Player settings) the video playback part is done. This gives you DTS playback also.
2. Unfortunately there seems to be a problem with Wifi communication, for which afaik no clear solution exists. I'm trying to see if another model router solves the issue since several posters on this forum reported having no Wifi issues at all. Maybe a topic should be started to see what router chipsets are causing problems.
Activate the, Force GPU Rendering, in the Developers Options , and see if it will make any difference.

Try turning off the Smart Screen options, like Smart Stay and Smart Pause etc. Maybe that will work?

Thanks for all the replies. After switching MX player to H/W + the video is smooth as butter. I also enabled Force GPU rendering in Developer Options as well. Looks like I'm good to go.
Appreciate the help.

I did this and my stock player still stops and plays every few secs. The on screen buttons come up and show it is pause. Its almost as something is reading that the screen has been pressed. My web videos play fine as does DicePlayer.
I am also having trouble with audio playback using Poweramp. The music gets louder and softer randomly, and i get distortion and crackling/popping sounds as well. Using the stock player seems fine.
Anyone have these issues?
Dice Player fixes the issue. Download it and make it your video player.

What's the Netflix fix?

Does anybody at Mad Catz have a thought on the matter? The hardware should be more than capable of running Netflix on a large screen without audio sync issues. Can you provide a proper app?

We're not seeing any audio sync issues here, and going by reports from other users neither is anyone else. What's your complete hardware setup and do you get any sync issues with other programs such as xbmc or YouTube?
I'm just waiting on HD Netflix...Quality on Netflix on MOJO is severely lacking. I don't have any audio problems (at the moment), but the video is very pixelated.
Streaming YouTube and other movie apps in 1080 or 720 works perfectly for me 85% of the time. I'm thinking my few issues with those is because my wireless router just reached 12 years old and is constantly dropping signal.....Going this weekend to buy a new one.

Actually, I was a bit hasty with my previous reply. My hardware set up includes a home theater sound system where the audio loops back through the TV. If I use the TV speaker, the lag is barely noticeable. If I turn off the TV speaker and use the amplifier, there is a very noticeable lag.

Yes, I was wondering if there was an amp in the loop, although the fact that it only does it for Netflix is a bit odd. Could you clarify though: are you connecting MOJO into the amp which then passes to the TV or are you connecting into the TV which is then passing audio to the amp (and, if so, what kind of connection? Optical? Phono?). If it is the latter then some amps have settings to accommodate for audio lag.

The MOJO is connected directly to the TV via an HDMI cable. Likewise, the amplifier, which is a Sony Model # STR-DH520, is also connected directly to the TV via an HDMI cable. I looked thru the manual and found a "SYNC ON" setting which delays the "output of audio to minimize the time gap between output and visual display" The delay time given is 60ms. I'll play around with it later today and see what impact it has. Maybe I had it on when it should have been off, or vice-a-versa. Thanks for the input on this!
I guess you're using all of the HDMI inputs on the amp already?

I will confess to having bought the TV and amp, etc., two years ago, and now I don't really remember what led me to make the setup choices I made at the time, but no, I wasn't using all the HDMI inputs on the amp, and frankly, I didn't even check to see if it had available HDMI inputs on the amp when I connected the MOJO. Connecting the MOJO directly into the amp and ensuring the correct A/V sync setting eliminated the delay completely. Thanks!

I have audio sync issues too. Audio seems to lag behind the video. And always when I watch netflix, the screen flashes, like gets smaller, idk how to describe it, often when watching shows. No matter what shows I watch it always does this. Probably 20 times at least throughout an hour long show.

If you've read this entire thread, you're aware my problem was similar to yours. I too had seen the occasional screen "flash" when watching Netflix. I'd recommend plugging your MOJO directly into your TV, using the TV's speaker, and eliminating any other hardware that might be in the loop in order to see if the issue truly lies in your MOJO, and is not being caused by some other component. Connecting my MOJO directly to my amp solved all my audio sync issues.

Mine is directly hooked up thru the TVs HDMI port. No difference if I have anything else plugged into the TV or not
And you're only using the TV's speaker? (rather than then output your TV's audio to an external speaker/amp?)
Are you running the 0110 firmware release and do you see the same issue with other video playback programs?

Yes, using the TV's speaker. My mojo came with the 0110 firmware release. Only Netflix has this issue. Have reset my wireless router to make sure that wasn't the problem either. Mojo is the only hardware hooked up to this tv.
If it would help, I could capture a video of what it's doing on my phone.

I no longer have any audio sync issues, but I do still see the occasional "flash" while watching Netflix. It looks like the image changes sizes for a fraction of a second. Haven't seen it with any other App.

Yes, that's the same problem I have with Netflix (along with the audio sync issues). It doesn't bother me enough to not watch it but it can be disorienting when watching at nite in a dark room. It does it a lot for me. I notice it the most when scenes change.
Edit:
I just got root tonight. I see on the Play Store that I can now update Netflix to the latest version. I will do that and get back to ya'll and see if that changes anything! As soon as I'm done downloading more games....
Ok, so last night I went out and bought a new TV for my MOJO. Picked up a 42" Sharp 1080p 120hz LED. I don't know if it's because this TV is 120hz compared to my 2010 32" Vizio 1080p 60hz, but the Netflix issue has been resolved. No more audio sync issues. I also noticed this TV has a Clear Motion setting, I have it set to on. Not sure if this has something to do with it either. Anyways, it's fixed, for now.
BTW, anyone looking for a deal on a TV of this relative size, it's a steal. Only $399 at Best Buy. The picture is awesome, and 120hz over 60hz is a night and day difference. Much more clear during on screen motion than my old tv. I'm very impressed. I can't imagine how good a 240hz or 480hz set looks like.
Edit:
Forgot to mention, the screen flashing/resizing is still happening. Very annoying. I really feel this is an issue with the app itself, hopefully it's getting fixed with an update. Can't wait to start watching in HD aswell...

Problem whit bluethoot audio

Hey guys, I have a problem with the bluethoot playback, it stutters for a second randomly. It happens once every 5 or 10 minutes but it's pretty uncomfortable, I go through a creative speaker bombox and my two cars, another Spanish forum there are more people affected, someone else is wrong? The rom is indifferent, I spent with kk and I still happening with llp, thank you very much
Edit: bluetooth, not bluethoot
I have the same issue. I use my phone to play music (on SD card) in my car vua bluetooth and also use bluetooth headphones for same music.
And glad you noticed the bluethoot typo lol
I was having a similar problem with Bluetooth and Poweramp. I started using the Samsung music player and haven't had any problems yet
sent from somewhere
Same here....
Another thread was just created that's related to this problem. People are suggesting things like custom kernels.
Unfortunately for me, my phone doesn't have a Root method yet. So I'd welcome any solutions that don't require root.

I"m having the same problem with my phone. Regardless of which device my phone is sycn'd with, car, blue tooth speakers the sound skips/stops for a second then starts up again.
Samsung support wasn't much help, their resolution was to send the phone in.
