: NVidia CK804
: Realtek ALC850 rev 0
: on-board (ASUS A8N-E)
: 10de:0059
: 1043:812a
: Analog Stereo works
:S/PDIF output works with additional configuration (see below)

==NVidia CK804==
In the LinuxMCE admin panel under "Wizard:Devices:Media Directors" set the audio to "CK804" with "AC3 pass-through" checked for the desired Media Director.
===ALSA Error===
The LinuxMCE 710 ALSA package has an error in the file
/usr/share/alsa/cards/NFORCE.conf

Change line 194, to be
device 0

instead of device 1

This has been fixed in Linuxmce 810 and now shows correct device number

===asound.state===
no change needed
===asound.conf===
no change needed
===xine.conf===
Make the following change to /etc/pluto/xine.conf<br>
Change "#audio.speaker_arrangement:Stereo 2.0"<br>
To read "audio.speaker_arrangement:Pass Through"

If you still do not have success with your CK804 chip, but the KDE sounds come out just fine, change /etc/pluto/xine.conf
Change "audio.alsa_front_device:asym_spdif"
To read "audio.alsa_front_device:default"

== Troubleshooting ==

If you don't have S/PDIF or HDMI sound check following:

* Digital sound is disabled by default. Run alsamix and unmute it (IEC958)

* aplay -l - display all playback devices. You should see digital one(s) - IEC958

* aplay -L - should display S/PDIF or/and HDMI. If you don't see them try to install the newest version of ALSA and maybe nVidia drivers if you use nVidia card. Here is a script to upgrade ALSA automatically from the sources - [http://ubuntuforums.org/showthread.php?t=1046137 ALSA upgrade script].
