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.

Dear Apple,


What the ****? I've been following this thread for weeks hoping for a resolution. I've tried all of the suggestions several times, and finally want to add my voice to the throngs of frustrated supporters. I've been unable to use my bluetooth headphones for weeks now and I really miss them. To be clear, they still work, but the sound is so choppy that it's like listening to a radio station that you can't quite tune into. Only this is worse, because I pay to stream my music and shows. I move around while I'm working so I can't use wired headphones. Please don't ignore this issue. We have nowhere else to turn.


Sincerely,


Still Waiting

Same problem here, have a 2013 macbook pro retina with a blue tooth connection to NAD D3020 ampifier and have lag with any type of audio. Spotify, online radio, streaming TV and local movies (which get progressively worse while watching. Thought it was me but not. Apple please do something about this, not very happy with my first mac!

I´m glad this worked for you.

But even if it had worked for me and everyone else I don´t think we should settle for such a solution since there´s no reason for Apple to allow the webbrowser to interfere with connecting a device, or the dashboard to interfere with transferring bluetooth-data. It would be like allowing my kitchen sink to interfere with the headlights on my car..

My computer (MacPro mid2009) works alright, but feels at least 3 years older after upgrading to Yosemite. I get half- and full error-situations I never got before, typical for a computer that is overloaded with something, be it buggy software or a very demanding task a user has started. Upgrading the OS should make the computer both "younger", more responsive and (even) more stable. I fear Apple is losing the discipline that Steve Jobs was known for and that is necessary to fuel quality in the computer world. If these things are not taken seriously I fear that more things will start breaking in mysterious ways.

kind regards

Im having bluetooth issues after upgrading to Yosemite as well. Im on late 2013 intel iMac and smc reset + pram did absolutely nothing. Also disabled dashboard, but it had no effect on the problem. With Mavericks I could connect my mac to my Sony stereo that has bluetooth and listen to my music that way, but now everytime I try to do that, I can hear music for 1-2 seconds and it immediately cuts off. This is a really, really huge issue, because I also listen to my productions from Logic X this way to see how the mix sounds on basic stereos and right now its impossible.

I'm with you, readytorun. I have two MacBook Pro 2011 models. One is running Mavericks and the other is Yosemite. Mavericks is great - I rarely have issues. For the life of me, I have no clue why I updated to Yosemite. I can't listen to music or watch video. God forbid I try to do two tasks at the same time. And now, every time my cell phone rings, my **** laptop starts ringing and won't ever stop - even long after the phone call is over. UGH.
