No Leopard Settings, maybe iTunes?
Hi,
I haven't been able to find any Leopard settings for the a2DP other than the ones under Bluetooth Preferences. You can get a couple more menus if you select your device and do things like SHOW MORE INFO or UPDATE DEVICE SERVICES.
Those things didn't seem to make much a difference, but I did notice that my headset sounds WORLDS better on my iMac than it does on my Macbook. I'm not enough of a techie to explain why that might be, but all I know is that even though both are running Leopard, the iMac sound is acceptable while the Macbook sound makes me want to cry.
The only adjustments I found that make any difference in the sound is in the Equalizer for iTunes. Adjustments made on that panel are reflected in the headset, but they can't compensate for a bad connection like the one between my motorola and my macbook.
Hope that helps...
