1) Am I saving settings correctly?
2) What is VIA DXS, VIA DXS 1, VIA DXS 2, and VIA DXS 3?

Some reason after I saved the settings (see below), exited X, and started X, It remembered The Master volume settings, but not the VIA DXS settings, so I had no sound... Why does it remember some of what I set?

Here's what I did:
jake$ startx
jake$ su root
root# alsamixer
[set MASTER, MASTER MONO, VIA DXS, and VIA DXS 1 to 100]
root# alsactl store
root# exit
