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
Change "#audio.speaker_arrangement:Stereo 2.0"
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 - ALSA upgrade script.
