[gentoo-amd64] weird sound problem

[Bernhard Auzinger]

Hi,

I did a kernel update to 2.6.24 (gentoo-sources), a update to the 
linux-headers 2.6.24 and a world recompile. After the recompile sound stops 
working. Every time I try playing sound under kde (gmplayer, amarok/xine-lib) 
I get the message "could not open sound device".

mplayer gives me this:

[AO_ALSA] alsa-lib: dlmisc.c:118:(snd_dlsym_verify) unable to verify version 
for symbol _snd_pcm_empty_open
[AO_ALSA] alsa-lib: pcm.c:2109:(snd_pcm_open_conf) symbol _snd_pcm_empty_open 
is not defined inside (null)
[AO_ALSA] Fehler beim Öffnen der Wiedergabe: No such device or address
[AO SDL] Samplerate: 44100Hz Kanäle: Stereo Format s16le
[AO_ALSA] alsa-lib: dlmisc.c:118:(snd_dlsym_verify) unable to verify version 
for symbol _snd_pcm_empty_open
[AO_ALSA] alsa-lib: pcm.c:2109:(snd_pcm_open_conf) symbol _snd_pcm_empty_open 
is not defined inside (null)
[AO SDL] Kann Audio nicht öffnen: No available audio device

I'm in the audio group. Logged in as root I get the same errors. 

On the other hand sound from TV works. Any ideas what is going on?

I solved it by setting the ALSA_PCM_PLUGINS.
