It seem that there are bugs in alsamixer 1.0.9a ( even CVS Rev 1.88 )

alsamixer -V capture

1) The volume (Line,CD,Mic,Video,Home,Aux,Mix,Mix Mono) cannot be 
changed in view capture.

2) The Mic Select(Mic1,Mic2) and Mono Out(Mix,Mic) controls are missing 
in view capture.

The above problems do not exist when using "alsamixer" or "alsamixer -V 
playback"

"vortexcontrol" (Vortex Control Panel) can be obtained from the support 
page in openvortex

http://savannah.nongnu.org/support/?func=detailitem&item_id=103017


If your au8810/au8830 has stereo codec

speaker-test -c 2 -t 2 -f frequency


If your au8810/au8830 has quad codec

speaker-tet -c 4 -t 2 -f frequency

The graphic equalizer will show left and right EQ peak values in
different bands when you change the frequency , please note that only
front channels are connected to the equalizer.
