[alsa-devel] Conexant CX20585 recording does not work
nix at go-nix.ca

My mom has a laptop with the following sound card:
lspci: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
Card: HDA ATI SB
Chip: Conexant CX20585
I can't record from this card no matter what I try. It seems that
alsamixer has a lot of options:
Mic B <Capture switch>
Mic C <Capture switch>
Mic E <Capture switch>
Mic F <Capture switch>
Capture <0% -- 100% slider>
Analog Mic Boost <0 db -- 40 db slider with 10 db increment>
I have tried to record from each mic in turn, I have tried the different
boost levels (0 db - 40 db), but I have had no luck picking up anything. I
have attached an external mic to the line-in, but no difference.
When I say "I have tried to record" I mean that I logged into her
computer, chose one of the mics from the above list, and then I told my
mom to say something while looking at the input sound level indicator in
the GNOME sound settings panel. On other computers, I have found this a
sufficient indication of whether the mic works.
Is this inability to record a known limitation of this sound card? If not,
is there some special setting I have to modify to make it work?
Please find attached the output from alsa-info.
TIA for your help,
