Map ALSA "PC Speaker" to IOCTL90 "MonoIn"

[rudi]

This should allow the PC speaker volume/mute on certain notebooks to be controlled via LBMixer.

Hi Paul,

looks good so far !

I'm currently running the new UNIAUD16 with an unmodified older version of UNIAUD32 and I can mute/unmute the speaker using LBMixer. Volume control doesn't work, but that is most likely a problem of that UNIAUD32 on my specific hardware...

Thanks !
