Okay. I have switched back to using irq5 (which is unused in my
system). It's really nice with this plug-and-play, that you can switch
around the settings - even if it means recompiling the kernel :-)

/usr/sbin/mixer also has problems. There seems to be only two volume
settings (the same goes for bass, treble etc.):
mixer +=sound,
vol -=nosound

Okay, I have tried recording with various settings
Here is output from ``ktrace pcmio +rec,stereo,8000,s16 4:0
/tmp/test3''. It seems it never returns from the first read. I have to
stop the program using Ctrl-C, and then wait a couple of second
(5-10). Then syslog says: ``timeout flushing dma2, cnt 0x0 flags 0x00000551.''
"-- format 8000,stereo,0x00000010, len 4 skip 0
