Hello, I've bought a new mainboard recently. I replaced my old mainboard with the new one (different vendor). The debian (unstable) installation is still the same, nothing has been changed. It means, I had working sound with my old mainboard. I booted it up - so far it seemed everything was okay. Unfortunately sound isnt working properly. As far as I see vlc is working sometimes with mp3 + some videos gmplayer is not aplay is not games are not amarok is not kde is playing with login music starting aplay results in: mcgreg@pegasos:~/git/drm$ aplay /usr/share/sounds/alsa/Noise.wav ALSA lib pcm_direct.c:1605:(snd1_pcm_direct_parse_open_conf) The field ipc_gid must be a valid group (create group audio) aplay: main:608: audio open error: Invalid argument (g)mplayer: [AO_ALSA] alsa-lib: pcm_direct.c:1605:(snd1_pcm_direct_parse_open_conf) The field ipc_gid must be a valid group (create group audio) [AO_ALSA] Playback open error: Invalid argument Failed to initialize audio driver 'alsa' Could not open/initialize audio device -> no sound. vlc mostly with ALSA lib pcm_direct.c:1605:(snd1_pcm_direct_parse_open_conf) The field ipc_gid must be a valid group (create group audio) [0x2c40b08] oss audio output error: cannot open audio device (/dev/dsp) games (nexuiz for example) ALSA lib pcm_direct.c:1605:(snd1_pcm_direct_parse_open_conf) The field ipc_gid must be a valid group (create group audio) this is all with user. the user mcgreg is added to the group audio.
