Note: Via does not produce sound cards - but their motherboard chip sets do provide an interface for audio chips mounted on the motherboard. See Sound Cards: Introduction for details.
If your VIA sound card does not work, type at the terminal window:
lspci -nv | grep -1 0401
Then find your card below, and set the correct module DXS setting.
