Hello,
I've a new (to me) laptop which is a Thinkpad W500 with a Conexant
CX20561 (Hermosa). I am having no luck getting the microphone to work.
The goal is to get skype up and running with sound, mic and video.
Presently I have sound from the machine. Trying to get the mic to work.
If I use skype's echo test it does not pickup anything. This is the
only 'mic test' I've tried. I'm am not much on audio so never had a
need before to use a mic under FreeBSD... so I don't even know what
other recording tests might be useful.
Here are a few bits of info....

%cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA Conexant CX20561 (Hermosa) PCM #0 Analog> (play) default
===========================
% mixer -f /dev/mixer0
Mixer vol is currently set to 75:75
Mixer pcm is currently set to 75:75
Mixer speaker is currently set to 75:75
Mixer ogain is currently set to 50:50
If I alter the hints mentioned above (by uncommenting the one), I can in
fact get a 'mic' to appear via mixer. But the sound output is lost.
Additionally, in such a configuration the cat of sndstat then reports
'(rec) default'. So I did not proceed with those hints as they were
seemingly of no use.
Any help is appreciated.
Thanks,
Eric
