Hi , i've a small problem with my headset
en usb stick from canyon.
I have no sound with my canyon CN-BTH1
I compiled kernel 2.6.11.9 with build in alsa
usb bluetooth : Canyon CN-BTU1
headset : canyon CN-BTH1
distro : SuSE 9.2
when i changes the sound volume the headset response perfecty with
noise, but thats it.
I tried with another usb-stick BT180 from trust (also silicone wave
chip inside) but there is no difference.
Who can help me ?
Thanx anyway !
Loopback from kmix don't do anything, but i haven't test this before..
starting :
modprobe snd_bt_sco (start as root)
kmix (starting as user)
at this time kmix found BT headset
starting btsco (as user)

headset and i see it changing on screen (btsco).
