thanks for sharing your scripts, very useful to me !
In fact i've been fooled myself with system messages doing this :
[seijitsu@localhost ~]$ amixer -D hw:DSP cset numid=5 0,8,12222
Could not find the specified element
Seeing these messages, i though it wasn't working, as by this time i hadn't
speakers connected to the soundcard to verify that the sound was actually coming
through... So this this actually works despite the error message... my fault !
[seijitsu@localhost ~]$ lspci

i have no idea what a "console-only"

do, but perhaps you could consider the following as inspiration also (which
uses amixer(1) to control the hdsp matrix mixer from the cmd line):

Very similar to the script I use to init a Multiface:
#!/bin/bash
# Multiface II mixer

A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
