[Bluez-devel] btsco and Sony Ericsson HBH-PV705 headset

[Miles Sabin <miles@milessabin.com>]

I'm having problems getting this working with Skype or aplay on an FC6
Sony Vaio laptop. btsco is fresh from CVS today.

The bluetooth connection looks good, SCO channel connections/disconnections
produce an audible click on the headset speaker, and kill -USR1 <btsco>
gives me a ringtone on the headset as expected. However, I'm getting no
other audio, either input or output. Any help would be much appreciated.

The details, as requested on the bluetooth-alsa Contacts page,
