Hello evertvaningen

Note also that if you need Alsa-config then be sure to load it before alsa extension.


Sorry I should have explained better the command is " amixer set "Master" 80 unmute "   but I think others helped out there..

To recap:
If you can boot from a clean system (without any backup alsa config files) whether that entails booting with alsa or "alsa-config + alsa".   Then able to hear sound by use of alsamixer to unmute and set desired volume then it's simply a question of which controls??  and then finding the names for these controls because the names shown in alsamixer are not necessarily a usable command name.  Confusing huh..?
eg:  To unmute an SPDIF device as indicated in alsamixer, we would use the IEC standards document name: 

--- Code: ---amixer -c 0 cset name='IEC958 Playback Switch' on
--- End code ---

After that it should be easy to setup alsamixer commands to control your card.

AIUI the volume index comes from the card, I don't think it's an alsa issue.  My hardware volume reports 0 to 100 so I don't have that problem and can't advise,
