Building alsa-driver-1.0.23 for sis7012

Building alsa-driver-1.0.23 for sis7012

[JD]

Hi devels,
I would like to build the driver for my sis audio chipset 7012,
but I do not see it listed in the list of supported cards, which
is printed out from ./configure --help
So, if I configure --with-cards=sis7012
will it actually support my chipset?

Best regards,

JD

I checked. Nothing is muted.
This is a big bummer for me because I cannot use Skype.
I uploaded the output of the shell script your refered me to.
The output is at

No, clearly things are muted (I've noted with arrows):

OK, then I have no idea how to turn them on.
The only mixer I have is
/usr/bin/gst-mixer
the title of which says:
Volume control: SIS si7012 (Alsa mixer)

I check every available tab or button for ways to turn
on the captures. I do not see any way to turn them on or off.
