Re: [SOLVED] Sound isnt working properly

["Gregor Galwas" <g.galwas@highantdev.de>]

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
Gregor Galwas
