I am SO glad you made a alsa plugin for the headphones.

I haven't been able to dig in but something looks wrong already... isn't the correct code going to connect on psm 25 first for the commands and then on the detected psm (usually 1) later for the stream? Yet from what you've sent it looks like the working version connects to psm 1 first?

If I read your diff wrong, then maybe it's just that the plugin incorrectly tries to go right to streaming without setting it up properly using the l2cap connection on psm 25.

I haven't been able to dig in but something looks wrong already... isn't the correct code going to connect on psm 25 first for the commands and then on the detected psm (usually 1) later for the stream? Yet from what you've sent it looks like the working version connects to psm 1 first?

Quoted 5 lines

If I read your diff wrong, then maybe it's just that the plugin incorrectly tries to go right to streaming without setting it up properly using the l2cap connection on psm 25.
