"alsamixer -c 3" on my machine selects Card: HD-Audio Generic, Chip: ATI R6xx
HDMI. So instead I invoked "alsamixer -c 0" since that selects Card: Microsoft
LifeChat LX-3000, Chip: USB Mixer.
Yes, adjusting the speaker volume using alsamixer worked as expected. Within
alsamixer, Speaker volume 0 was reported as dB gain: -28.37, -28.37. Speaker
volume 100 was reported as dB gain: -0.06, -0.06. The change was smooth across
the range 0 to 100.
