yes (Audio CD, Youtube...) but I can't change the software volume
control(ALSA, OSS, GNOME are without effect), it works only at the
speaker box volume control cable.

I used the onboard soundcard (analog&digital output) from my ASUS
M2N-SLI Mainboard. (green output for front speakers)
For better understanding, I attached a picture of the speaker ports.
(2.1 analog boxes [2 satellites, 1 subwoofer] with one green soundcable)

ich at debian:~$ id
uid=1000(ich) gid=1000(ich)
