this is my first post to this mailing list. I hope someone can help me 
with this question.

A few days ago I first tried the new audio/madfufw ports and it works 
very nicely for playback. But I can't get the mic to work as rec device. 
With mixer I get the following:

#mixer -f /dev/mixer1
Mixer vol is currently set to 75:75
Mixer pcm is currently set to 75:75
Mixer mic is currently set to 100:100

#mixer -f /dev/mixer1 -S =rec mic
mixer: unknown recording device: mic

The rest of the output (dmesg, sndstat, sysctl...) all looks like it 
should have rec capabilities. Is there any variable that I must manually 
enable to get the device to work for recording?

Here is the output of the different commands:

uaudio0: <Transit USB> on usbus2
uaudio0: Play: 48000 Hz, 2 ch, 16-bit S-LE PCM format
uaudio0: Record: 48000 Hz, 2 ch, 16-bit S-LE PCM format
uaudio0: No midi sequencer pcm1: <USB audio> on uaudio0

cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386)
Installed devices:
pcm0: <HDA Analog Devices AD1981HD PCM #0 Analog> (play/rec) default
pcm1: <USB audio> (play/rec)

dev.pcm.0.rec.vchans: 2 dev.pcm.0.rec.vchanmode: fixed
dev.pcm.0.rec.vchanrate: 48000 dev.pcm.0.rec.vchanformat: s16le:2.0
dev.pcm.1.rec.vchans: 1 dev.pcm.1.rec.vchanmode: fixed
dev.pcm.1.rec.vchanrate: 48000 dev.pcm.1.rec.vchanformat: s16le:2.0

Does anybody have an idea of how to get the Transit to work as rec 
device (or how what else to do with the mic device so that I can record 

Many thanks for any suggestions.
