Hi!

I just tried btsco with the latest (Alpha 6) Interpid Ibex version.
Results:

- modprobe snd_bt_sco  -> works fine
- btsco [mac]  -> as ubuntu user:

Error: control open (hw:1): No such file or directory
Error: Can't find device. Bail

- btsco [mac of headset] as root

starts fine, pairing works, but:

1. /dev/dsp1 is created fine but device is visible neither in Sound preferences 
nor in Ekiga device selection list
2. ps ax|grep btsco shows the process in sleep state (S)
3. mpg123 -a /dev/dsp1 something.mp3 as root prints:

Error in writing audio (Input/output error?)!

After this ps ax|grep btsco shows the process is dead (D)

syslog:
