Hello,

can someone help me with the problem below? Is ofono supposed
to expose an audio card when a headset is connected? If so, could
you explain how this happens?
I am not using SELinux and have ofono and pulse compiled from a
recent source. The rest of the system is Debian unstable witch ships
Bluez version 5.23.

If this is not the right place to ask such questions please tell me, I
never received any response to my previous mails.

Regards
              Georg
