Comment 38 for bug 393523

@jean francois:
Try installing a current alsa snapshot and maybe a newer kernel.
/dev/snd/hwdepC0D0 not being found means alsa does not detect your card correctly.
after upgrading alsa, try
sudo -s
wget ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/hda-verb/hda-verb-0.3.tar.gz
tar xf hda-verb-0.3.tar.gz
cd hda-verb-0.3
make
cp hda-verb /usr/bin
hda-verb /dev/snd/hwC0D0 0x1c SET_EAPD_BTLENABLE PCM
