Thanks for the hint

I tried with blueman-1.23:

A Bluetooth headset will connect using a "headset" profile, but not as an "A2DP sink"
Bluetooth headphones will not connect as an "A2DP sink"

I suspect the issue is audio.conf, but without knowing the command line syntax to connect the audio profiles, it's a little difficult to troubleshoot.
