ALSA and other sound devices: entire section
Looking around to see how others handle the sound stuff
A draft proposal attached (of course, this should be split into two
files, one for naming and one for volumes).
It correctly names sound devices and assigns permissions. It restores
ALSA volumes, or, if it looks like ALSA is not used at all, OSS volumes
(specially for Archaic if he still uses the proprietary nvsound module).
Things not done:
1) stable naming of OSS mixers.
2) ALSA-specific firmware loading
