Mac OS A2DP and FreePulse Logitech Headphones
Apple is slowly fixing the many issues with it’s A2DP driver. In 10.4 the driver would kernel panic as often as it would work. In 10.5 it’s functional but only with a special trick to get it to change the audio channel correctly. Simply turning on the headphones and clicking “Use Headphones” on the dialog rarely works.
The trick is to run through this sequence twice. Turn on the headphones by holding the button on the right ear. After you hear the ping Mac OS will prompt you to use the headphones. Choose the option to use the headphones and the bluetooth icon will switch to connected. Now turn on the headphones again and when you hear them ping the bluetooth icon should switch back to disconnected. Under the bluetooth menu choose “Use Headphones” under the FreePulse device. The icon will stay disconnected but when you play audio it will switch to connect and start functioning.
I couldn’t find a place on apple’s site to report the bug with repeatable test case. If any of you know how to report bugs in Mac OS please tell me and I’ll file it so hopefully this behavior is fixed in future releases.
