Bluetooth audio in OSX Lion

What does this mean? That you have no bluetooth issues in a 2.4ghz environment? I never said all 2.4ghz environments cause the issue, just that congested ones *might* since they cause interference with the bluetooth band.

My own experience is that *all* of my devices (a 2008 Macbook, 2011 MBP 15", ICS Android tablet, JB Android phone, iPhone 4S, and Blackberry Playbook) all have issues with bluetooth when I have the 2.4Ghz band enabled. On the 5ghz band there is little to no problem. (Lots of others in my neighborhood use the 2.4ghz band so there's interference caused from outside my home too.) Things might be different for others, but I recommend exploring this radio band issue as a potential cause.

To delete the duplicate entry, use defaults delete "My Bad Entry"

sweet, for anyone else reading, the solution was to type this into the terminal…

defaults delete com.apple.BluetoothAudioAgent "Apple Initial Bitpool (editable)"

and that got rid of it, thanks for the confidence boost coolspot. I started doing stuff like that but didn't want to break anything. It's all working great now, with these settings…

defaults read com.apple.BluetoothAudioAgent

{

"Apple Bitpool Max (editable)" = 75;

"Apple Bitpool Min (editable)" = 45;

"Apple Initial Bitpool (editable)" = 20;

"Negotiated Bitpool" = 45;

"Negotiated Bitpool Max" = 53;

"Negotiated Bitpool Min" = 45;

"Stream - Flush Ring on Packet Drop (editable)" = 0;

"Stream - Max Outstanding Packets (editable)" = 25;

"Stream Resume Delay" = "0.75";

}

Thanks again!

Thanks for the post. I changed the Mhz on my Wireless Utility (have Airport Extreme) and everything works great--I tried 5 Mhz but it didn't work as well at 801.11n. Bluetooth now works like a charm in every app that I want to use it for--movies through the browser, of iTunes and sound in general as beforre under Snow Leopard. I was going crazy before and could not get even a connection at all with the Sony Bluetooth Headphones. Thanks.

Hi,

I tried these settings but still now worky....now i seem to have screwed up my ability to make calls using Google Voice though (nothing else changed). Do you happen to know what the orignal default settings are? I wrote them down but then lost the piece of paper!

Thanks in advance!

sgamgee,

Entering this into the Terminal will get you back to the default...

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Max (editable)" 64

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" 35

defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool (editable)" 40

defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool" 35

defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Max" 53

defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Min" 35

defaults write com.apple.BluetoothAudioAgent "Stream - Max Outstanding Packets (editable)" 15

hope that helps

Thanks much! That did it...back to normal!

I can now confirm this has been fixed for my Sennheiser 550MX headphones in 10.8.3.

Kaomaru's solution WORKS. Thank you!

I have Turtle Beach PX5 headset, it works with all my gadgets fine, except iMac on Lion, I tried solutions posted above and it didn't work, after default restore headset works even worse. It's really weird. Is there any way to solve it?

Thanks

Using a Logitech BT Wireless Speaker Adapter w/a MBP Mid-2010, have been reconfiguring the BT pref files for some time now. FIgured it was time to contribute.

Most recent settings are as follows:

"Apple Bitpool Max (editable)" 80

"Apple Bitpool Min (editable)" 53

"Apple Initial Bitpool (editable)" 40

"Disable HFP" Integer 1

Enable AptX Codec

"Negotiated Bitpool" 58

"Negotiated Bitpool Max" 58

"Negotiated Bitpool Min" 48

"Stream - Flush Ring on Packet Drop (editable)" 30"Stream - Max Outstanding Packets (editable)" 15

Stream - Use dynamic bitpool (editable) 15

"Stream Resume Delay" "0.75"

In the Bluetooth Settings for this particular device,

* On and Discoverable = Checked

under Advanced

* 1st three boxes are checked, Reject Incoming Audio = unchecked

* Serial Ports (on = checked, key = unchecked, Name = Bluetooth-PDA-Sync, Type = RS-232)

Going to test, will report back.

So I've tried following everyone's ideas, and settings etc.

I just could not get my Jabra Halo 2 to work properly. I get static, dropping, music stops/starts

Finally, after all this time I found the problem.

While playing the music and trying to troubleshoot it I wanted to pack my mouse away so I turned OFF my Bluetooth Magic Mouse and voila! the sound immediately corrected and sounded perfect.

So I turned the mouse back on - 30 seconds later the Music is all choppy and disconnects.

Turned mouse off - immediately works fine.

So, if you are at your wits end and you have any other bluetooth device connected try turning it off and see if that helps.

Never thought to try that, I use a Magic Mouse but whenever the popping would start I'd just shut down BT and restart it. Great sugguestion dimitri.

To follow up my post above, this combination is working incredibly well. For my setup at least it appears I've finally found a workable combination! After about a year of toying with the BT pref file this is pretty exciting.

Should also note that I've been using this great little app called Pref Setter to make said adjustments. Works great with Lion/ML and best of all it's free.

Absolutely crazy that these devices have these problems these days. I have the same problem but it has nothing to do with Mail because I don't use it at all, so there is something else to blame.

2013 Macbook Pro, with Mountain Lion, but can't connect using bluetooth without issues. Ok...

Rec-connecting my speakers in the Bluetooth window by clicking "Don't Use as Audio Device" and then "Use as Audio Device" did the trick for me
