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.

Same problem with me too, using 2009 White Macbook and sony bluetooth headset. Delay gets progressing over time. Initially I thought it was a problem with browser, but same issue with local video file or audio file. Irrespective of application used, delay is due to bluetooth connection. Looking for fix soon in OS X Yosemite

this is absolutely ridiculous. i cannot even watch a 3 gb movie in vlc without the entire system slowing down if simply i open a safari blank web page in addition to vlc.. it is deeper than bluetooth i think cause i disconnected my headphones to test the multiple problems i have since upgrading to Yosemite.


I also have system problems with my icons and when i close out of vlc after a audio/video delay it leaves a shadow window of the program for about 2 seconds after I've closed it. the audio remains playing as well for the same amount of time the delay was. i am constantly emptying my trash of system cache so i can never get a plain set of circumstances that dont interfere with the problem. my icons look like this

Same problem here! Macbook unibody 2008 paired with Harman Kardon Squire through bluetooh.


Sound lag and glichtes from time to time when I make the computer to think a little bit. Opening windows, apps, surfing internet, etc.


It's really annoying this issue. Not solved with a clean installation of Mavericks. I believe Apple has created a new api for audio...


On the other hand. the system looks not so bad and is faster. But if this continue like this I will go back to Mavericks within one week and lets see.

I was wondering as well - should my e-mail notifications be appearing even if I dont have [apple's] Mail application open all the time? I seem to remember getting notifications I had gotten email before Yosemite. now I need to open my mail program to see if I email. This is related because if I need to keep an application open this will only add to the video problem and audio delay. I need to know when I get my emails.

I been in other forums trying to figure out my problem and was told by someone, after posting my comptuters data report using Etrecheck, I had malware inside my computer. I have no idea if this could relate to anyone else problem - or mine - but I thought I'd share the page he sent me to.

Guys i fount a solution for this issue. A part of coming back to Mavericks, we can also buy a dark blue paint, paint all the surfaces of our Macs, and throw them to the sea. Also lakes and rivers are pretty efficient, but i do suggest the sea for the vastness of its waters.


Sorry for the disappointment, but i find this problem totally unacceptable. We are talking about a stupid bluetooth connection with (usually) expensive devices.
And Apple could at least tell us that they are working on it.

Hey zeca


I agree, this should be the next logical step. Its a shame we cant get any response from Apple's recommended official support site.


If Apple is not responding, we have to wonder if they're actually even aware of this issue or just ignoring us to avoid the embarrassment. Im pretty sure its the latter. From what i read this is not the only issue with OS X Yosemite, apparently there are some wifi issues as well.
