I was deciding for some time which platform use for my HTPC and this
board was the first with low voltage processor and several PCI ports
(2xPCIe, 2xPCI) that allowed me to place in it 2xDVB-S2 cards and 1xDVB
card opossing to only 1 PCIe slot with Atom boards so choice was clear ;)
As far as Linux experience with the board there is number of rough
corners but level of support is already increasing by the day

It does not work yet as it should. I have the stereo sound in few apps
which allow me to pick the second audio device Realtek AL887-VD in the
configuration menu. First is HDMI Audio which does not work yet with
Open Source driver on Evergreen chipset [4]. I am bugging xf86-video-ati
guys about it to get that supported as well :P .However sourround does
not work in any configuration as card is not detected properly.
Alsamixer does not make "Line In" and "Mic In" as shared devices and I
am not able to configure them as output. Board user guide says that
"Line In" should work as "Rear Speakers Out" and "Mic In" should work as

I'll create bug report with Gentoo bug tracking system, but looking at
the matter historicly in case of drivers Gentoo it is very depended on
the upstream to resolve bugs in them.

I must say I didn't know I should create bug with Kernel BTS. Alsa-devel
mailing list seemed most appropriate place to seek help after forums and IRC

[2] was a great read and will definely get back to it once video driver
allows it but for now I would like to concenrate on proper mini jacks
