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 thought that my woes had finally been resolved with the update, as the lag seems to be (I'm not holding my breath) fixed! Then, low and behold, after simply toggling form one tab to another on Chrome, the most deafening white noise came blasting out of the speaker (Bose mini soundlink) It nearly made me soil myself, which at the age of 40 is not something I appreciate.


Surely Apple can get something fixed with this? It's gone on so long now, they have lost a lot of good will with me.

Well, I wonder if Apple is going to pay for the visits when I have to go see the doctor about my hearing loss. There is no rhyme or reason to it, which is frustrating on its own.


Just now I was listening to an audiobook on iTunes and someone logged into Skype and BAM. White noise and pain. It's like a new torture device. I never know when to expect it.


Come to think about it, Apple may have to pay for my psychiatric visits, too...

I am currently using a Beats Pill Plus connected to my Macbook pro. I have been having this 2 second delay problem with Beats Pill since day one. I tried connecting it with many devices and the delay was always there. But, since I only use my Beats Pill for blasting loud music, I never really thought about solving this problem. I would always switch to my Sony XB950-BT for YouTube videos and movies.


Recently, it seems like bluetooth audio delay is becoming a problem for many people, so I went online to look up this issue again in hope of that there would be some updated solution for this conundrum.


So I just tried the method you suggested and I'm NOT making this up: the delay was reduced from 2 seconds to about 0.5 second. Still can't watch videos tho. But it's certainly nice to learn some tricks about system reset.😁
