Bluetooth audio lag

Just updated (17th.Oct.2014) to OS X Yosemite. Im having trouble with bluetooth connection. There is an audio lag on my bluetooth headphone which progressively gets worse. Im using Sony DR-BTN 200. Is there a temporary solution until they fix it?


P.S. I found others with similar issues as well. Ive tried re-pairing the connection to no avail. Any help would be appreciated.

MacBook Pro, OS X Yosemite (10.10)

The storage of the Bluetooth audio values have been changed in Mavericks / Yosemite the defaults are now with a process called “Bluetoothaudiod”, you can change the defaults by using the following example:

Sudo defaults write bluetoothaudiod "Apple Bitpool Min" 50

Please see below all the parameters I have changed, to read the defaults please enter the following command in terminal:

sudo defaults read bluetoothaudiod

enter your password:

MacBook-Pro:~ Ciaran$ sudo defaults read bluetoothaudiod

{

"AAC Bitrate" = 320;

"AAC CBR" = 1;

"Apple Bitpool Max" = 64;

"Apple Bitpool Min" = 50;

"Apple Initial Bitpool" = 50;

"Disable AAC codec" = 0;

"Disable AptX codec" = 0;

"Disable HFP" = 0;

"Enable AptX codec" = 1;

These setting work well with my Bose Soundink OE headphones, please be careful entering the values as they are case sensitive, I really hope this helps some of you out there.

Cheers.

I submitted a bug report with a direct link to this post in the hopes that they would receive other bug reports as well and fix the issue with the next release of Yosemite. It's definitely out of our hands at this point anyway, and if everyone that posts here also sends a bug report (perhaps with a link to this thread too), that should get their attention, because this thread is growing large enough to show that everyone is experiencing these issues.

Months old MacBook Pro (Retina, 13-inch, Mid 2014) worked fine with Mavericks, but have progressively worse audio delay using any of several bluetooth headphones or my Big Jambox speakers.


This reminds me of when I upgraded to Mavericks and suddenly previewing images (with spacebar) went from instant in last OS to taking several unbearable seconds in Mavericks. Many threads exist on that issue, and Apple never fixed it. We already gave them our money, so they could not care less, I reckon!

Unfortunately, disabling dashboard seems not to work for me. FYI, I had already had the dashboard disabled since upgrading. But I tried re-enabling it, and then disabling again... just in case... but no. Still have the audio lag. And sad to report last night the lag turned into a crazy jitter that made listening to music absolutely impossible. Small noises worked OK, but nothing continuous was bearable. Today it is back to the normal several second lag... annoying, but OK for listening to music at work.


I LOVE APPL SO MUCH. . .

everything seemed to be working until i played an online game while listening to iTunes.

the games audio quickly went out of sync. once i quit it and returned to the desktop bluetooth worked in sync again.

when i throw away trash, listen to iTunes and play an online game - it goes out of sync.

its a lot better - this was the only instance of noticeable audio lag - than before but still a bug.

with plugged-in headphones there is no issue.


just the online game and iTunes seems not to bother it.

Have the same issue with Logitech bluetooth audio adapter from the moment I've upgraded to Yosemite. The latest update does not fix the problem. I get when the first version has a few bugs, but after this issue was reported by like everyone who's using bluetooth audio and Apple still has failed to recognize it and include a fix in this update... Gee. Very disappointed.

its been a while now since i did the clean install of Yosemite and i was too lazy to do another one for mavericks. I have to say though that the lag is much much less than it was before the clean install. Especially Quicktime seems to be ok. Ill leave it athis for now.


Btw, another Bluetooth bug - I now know that my headphones wont connect when my external display (with audio over DP) is conected. Only if i disconnect it, the Bluetooth Headset will conect. Also Safari cannot be open during this! Must quit before and then re-open.


So much fun to figure out this stuff. Deja-vu of my Windows days.

I've been experiencing the similar issues with my Bose AE2W bluetooth headphones when playing music after updating to Yosemite. Songs skip/stutter every other second making it a very frustrating experience. No issues with the headphones when paired/synced with other devices. The headphones are basically rendered useless until this gets fixed. I'm more than willing to work with a tech/engineer to help troubleshoot.

I've "updated" to 10.10.2 once before and found that, while the lag was not as noticeable, the popping in audio transmitted via Bluetooth was even worse. I immediately used time machine to go back to Lion. Having a bit of faith, I "updated" again recently. Before, there were periods of time that the audio would pop and skip separated by others in which the audio sounded okay, just delayed. Now, the delay is not there, but the popping and skipping is nearly constant. This definitely isn't good enough for me. It seemed that the popping would reduce if the system volume was constantly being adjusted, but that may be a delusion. Anyway, having to adjust the system volume up and down just to get a steady stream of audio via Bluetooth is ridiculous. Still hoping for some new info and/or help with this problem.
