--------------CUT------------
dmesg contains some interesting things about device 00:1b.0 (=the soundcard):
--------------CUT------------
[ 44.939043] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 22 (level, low) ->
IRQ 22
[ 44.939072] PCI: Setting latency timer of device 0000:00:1b.0 to 64

[ 45.007066] si3054: cannot initialize. EXT MID = 0000
--------------CUT------------
the volume for virtually any channel is at 100%, but everything remains
silent.
This looks similar to bug #39517, but as I am running feisty with
2.6.20, this should not be a problem.
I've also tried to use the latest and greatest alsa-drivers directly
from alsa, but also without success.
any ideas?
