Fix Yosemite Bluetooth Sound Issues

yosemite-sound-issues.md

1. Run the following in your terminal.

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Max (editable)" 80
defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" 80
defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool (editable)" 80
defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool Min (editable)" 80
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool" 80
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Max" 80
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Min" 80

2. Restart bluetooth (turn it off and on)
3. Connect as usual
4. No more popping! At least for me.

Thank you. It seems to help

FYI, if you open Bluetooth Explorer, then select Utilities > Special Options…, there are settings for the bitpool min and max values (although there are just 2 of them). They seem to have a maximum value of 64.

Of course, it’s totally possible that the UI limits the value to a maximum of 64, while the software may be able to take higher numbers. I’m not certain.

Thought I’d mention it, just in case it matters. (Probably not. But, you know…“just in case”.)

I had a squeaking sound problem and this seems to help a bit. Still not perfect though.
Thanks!

Awesome, worked for me. Thanks!

3hs and counting, works perfect. Thanks!

it still switches to low quality on skype calls

@lukasa1993 the low quality is because it is turning on the Mic and going into the Handset profile (which sounds terrible)

Anyone know how to stop the bluetooth mic from enabling by default?

Thank you ! it do works!

Has anyone figured out how to prevent the Bluetooth device from automatically enabling itself? It is quite the chore to having to deselect it every single time the headphones connect to the computer (handset profile sound is awful).
