salsa seems to be a utility to save and restore alsa control state 
during shutdown/startup. No man page. Salsa seems to be independent of 
alsactl as saving state with salsa is not the same as with 'alsactl 
store'. alsactl stores it's configuration in /etc/asound.state. I'm not 
sure where salsa stores it's settings.

Also, I couldn't find any reference to alsactl or salsa being called to 
restore sound state in any of the startup scripts. Hence the default 
"factory settings" every time you reboot.

Instead of putting `/sbin/alsactl restore` in rc.local, putting 
`/sbin/salsa -r` will restore the settings in place during the last 
shutdown. Better, yes?
