Ok, found the problem - kind of.
1. /etc/group was *READ*/write only to root. group/other were totally
forbidden.
Alsa couldn't read /etc/group and could't check if a user has the right to
play audio
-> ALSA lib pcm_direct.c:1605:(snd1_pcm_direct_parse_open_conf) The field
ipc_gid must be a valid group (create group audio)
2. knotify4 was blocking the sound. I renamed it. Done. Now everything
play fine, even 5.1 sorround-sound is fine.
Thank you for your help :)
Greetings

About the driver module ... I guess so? Since as I wriote in my first
mail, kde is able to output sound - I hear the kde jingle when you log
in (the screen ends botting) and vlc can play some files. dunno why or
how.
That's a clue that aRts has taken over your card.
Try a native KDE audio player.
