 Hi,
 I know this might seem a duplicate of #128, but I have no applications
 running, no hald running, and the soundcard should be "statically
 detected".

 I currently have two "soundcards": one is a modem, one is the effective
 soundcard. They get strangely detected by BIOS: one is hw:0 on time, and
 (randomly) on the next boot it might be hw:1... but this is another story.

 I've tried to "cat file.wav >/dev/dsp1" (dsp1 being the "real" soundcard),
 and it works. I haven't anything sound-related running (oh, well, apart
 padevchooser), and ALSA is stopped.

 Here's the error log:
