Although those three sound cards (au8830, emu10k1 and ymfpci) support
mono playback and capture.
None of them use the AC97 "Master Mono" pin for output.
gnome speaker-test show only one speaker
"Master Mono Playback Volume" was also removed from emu10k1 driver but
still exist in au8830 and ymfpci driver
There is no "mono" volume control for capture volume.
There are "LFE on mono" in unity settings/sound in ubuntu 12.04 for
au8830 and ymfpci which still have "Master Mono Playback Volume" but
"LFE on mono" is not exist in gnome settings/sound Fedora 17 Live CD
Also My Creative 4.1 speaker set only have green and black jacks
(Surround40) supported by emu10k1 and au8830
Can anyone explain "Analog Mono Output" and "surround41" in pulseaudio ?
