I have the GV-N220D2-1G1

forgot to check about getting one without a fan, but it's quiet so
it's fine so far.
I went to the PC store because a drive in my RAID array died, and a
2nd one was clicking and mdadm refused to start the array.. so I
didn't think through stressing that I had lost all my data. They were
on special so I got one.

I installed the 1.0.23 alsa drivers, library and utility..
I completely disabled the nvidia audio motherboard chipset and the
hdmi audio in the bios (9400M chipset)

So far, it's pretty good. And the weird artifacts I saw with the
260.19.21 drivers are gone. No more grey background, ghost images and
the like.

Also worth noting, I got audio working of the DVI port, I was a tad
concerned audio would only be off the hdmi port, but I only had a
DVI->HDMI cable available.

starting alsamixer, there were 4 SPDIF devices, I unmuted them all.

Kernel is 2.6.32.25

I didn't configure anything whatsoever with this card, no module
configuration, nothing
