hi all

i've problems with alsa in my ibook2.2 since i upgraded to 2.6.14.2. i can't 
listen anything after a wakeup. this is the mplayer output:

[AO OSS] audio_setup: Can't open audio device /dev/dsp: Device or resource 
busy
alsa-init: 1 soundcard found, using: default
ALSA lib pcm_dmix.c:819:(snd_pcm_dmix_open) unable to open slave
alsa-init: playback open error: Device or resource busy

also alsaconf doesn't find any soundcard ! alsamixer finds the soundcard, but 
nothing else ...

everthing worked with the last kernel ... what do you think ?
