[Bluez-devel] No sound with Canyon CN-BTH1 and CN-BTU1

[Teun <Teun.Kaptein@planet.nl>]

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)

Device is 1:0
Voice setting: 0x0060

when changing volume from mic of speaker in kmix it changed in my
headset and i see it changing on screen (btsco).
