Post subject:  ASUS M3N78-EM motherboard

I have tested ASUS M3N78-EM motherboard with Knoppmyth R5.5

* Socket AM2/AM2+ - AMD Phenom™ FX / Phenom / Athlon™ / Sempron™
* Integrated NVIDIA GeForce® 8 Series GPU with HDMI/DVI/RGB
* Realtek® ALC1200 8 -Channel High Definition Audio CODEC with optical S/PDIF out port at back I/O
* NVIDIA built-in Gigabit MAC with external Realtek PHY
* 1 xUltraDMA 133/100/66/33, 1 xExternal SATA 3 Gb/s ports 5 x SATA 3Gb/s ports (Use SATA1-3 for IDE mode.), NVIDIA® MediaShield™ RAID Support RAID 0,1,0+1,5,JBOD

Installation - flawless

Onboard Nvidia 8300 GPU worked out of the box, analog sound worked, Gigabit ethernet worked

I only needed to fiddle with enabling digital spdif sound via optical cable.
To enable it just edit file: /etc/modprobe.d/sound
so that it has this line:
options snd-hda-intel index=0 model=6stack-digout

sound chip on this via lspci -v command:

I got R6 going on this motherboard, using the HDMI output.
Installation went smoothly.

The above change was implemented, but I am not sure it was necessary.
To finally get it working, I had to unmute in 'alsamixer'.

NOTE: I disabled analog output in the Bios, which kept HDMI as the only valid audio output option . Only the 'Internal' audio was activated.
