Re: [Bluez-users] step by step - how to get your bluetooth stereo headset fully working with the bluez software stack under linux

[Terry Johnson <terryrjohnson@gmail.com>]

Hi All,

I've got a BlueAnt T8 that I've had working under Ubuntu for about 10 
seconds. Ever since that early success, the device will pair, but that's 
about the extent of it.

I've installed Blueman and that works marvelously, except for getting 
actual audio out. I'm running out of hair and wish there was some 
documented way to debug this process. Even being able to identify the 
failing subsystem would be wonderful. If such a process could be 
detailed in a Wiki I'd be more than grateful.
