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.

Hey Nataku


Thanks for clearing that up and reporting it. Makes sense. I searched for 'official bug report system', seems like you need to be a developer to report there. I have registered a developers account but am not sure if i can post it ( im not a developer)

Would appreciate if other developers here could report this bug.

Hello


yep, reported on every possible channel I could find. No angry talk, nothing like that, just calling their attention to the detail


now, as I follow most of those websites, I also know that, even after it's been reported on them, it still takes a while for apple to react. The only thing making them work fast is a lot of feedback. Just a few guys won't do it. Which is perfectly normal, given the number of clients they have. That is why we have to get leverage on this thing, so that they can distinguish it from every other guy who drops his Mac and starts saying Yosemite broke his laptop.

I just bought a pair of bluetooth headset finally and I, too, am experiencing lag and / or sudden drop in audio quality. The headset in question is the Creative Sound Blaster EVO Zx and the OS I'm currently running is OS X 10.10 running on a 27-inch iMac (Mid 2011) [iMac12,2] . It is quite important to me, personally, that this issue be resolved soon...
