  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
  [   44.949961] hda_codec: Unknown model for ALC660VD/ALC861VD, trying auto-probe from BIOS... 
  [   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?
