Hello,

I have the above modell running 9-CURRENT, but can't get the build-in
mic recording, only the jack for the mic in the headset records fine in
Skype;

here are the output of /dev/sndstat and mixer(1):

$ cat /dev/sndstat 
FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386)
Installed devices:
pcm0: <HDA Realtek ALC272 PCM #0 Analog> (play/rec) default
pcm1: <HDA Realtek ALC272 PCM #1 Analog> (rec)

$ mixer
Mixer vol      is currently set to  66:66
Mixer pcm      is currently set to  40:40
Mixer mic      is currently set to  70:70
Mixer mix      is currently set to  74:74
Mixer rec      is currently set to  75:75
Mixer igain    is currently set to  57:57
Mixer ogain    is currently set to  65:65
Recording source: mic

mixer(1) let me set for recoding only 'mic' or 'rec'. I'm attaching as
well the output of verbose messages grep'ed for pcm and hdac.

Btw: Is there some tutorial for the settings mentioned in snd_hda(4), I
don't understand the man page without more background info :-(

Btw II: Is there some test recording software that let me just record
from /dev/dspX and play it back (to not use Skype for such tests)?

Thanks in advance for any help

	matthias
