Subject: [Bluez-users] BT headset doesn't work: SCO packet for unknown connection

I've got 2.6.24 with bluez libs/utils 3.25

I have successfully paired my headset and PC, I can l2ping it and get info.
As soon as I try to play some audio (via mplayer) I get the following in the
logs:

force_scofix=1 doesn't help.

Any hints?

this is probably one of the adapters that the bluez driver cannot use
with sco. That's what I meant by "we can't do sco"

I've just tried windows and it works flawlessly there. So this is not adapter
problem - toshiba bt stack can do this.

Hey

I think that error indicates we can't do sco using your bluetooth
adapter. Which one is it?
