Must be blind. Anyhow, i guess this doesn't sound good for sound:

# hciconfig hci0 revision
hci0:   Type: USB
        BD Address: 00:60:57:02:7F:E1 ACL MTU: 192:8  SCO MTU: 64:8
        HCI 12.7
        Chip version: BlueCore01b
        SCO mapping:  PCM

I have problems with no audio on this dongle. So i take it, that it
might be the oldish firmware.

Kind regards,
Martin List-Petersen
