[alsa-devel] snd-via82xx setting

[Benjamin Hovey]

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
