FYI, the below system required the following non-default settings for ALSA to play any SPDIF output correctly. Prior to finding this setting, output from different sources, WAV, MP3, CD, etc, were played at a slightly faster speed than they should have.
snd_via82xx: dxs_support=3
When installed, the default setting was dxs_support=5.
Hope this helps. I am new to Linux and it took me quite a while to find out how to set this setting (I put it in /etc/modprobe.d/alsa-base.conf) Cheers
