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?

Hey

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

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

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"

You may have to keep the option, or not...

Please try this kernel patch and report if it fixes your problem.
