Hi!
My mom has a laptop with the following sound card:
lspci: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40)
driver: snd_hda_intel
alsamixer: 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,
Please try the model quirk "hp-laptop". In Ubuntu that would be adding the line:
options snd-hda-intel model=hp-laptop
to the file /etc/modprobe.d/alsa-base.conf
I guess it's the same in Fedora. If it works, we'll create a quirk.
(Memo to self: You should really help out with that cxt5066 autoparser someday.)
