Since you have a rec option in your mixer.... I would go ahead and set
the record input (which you probably already did)
mixer -f /dev/mixer[device] =rec [ line, mic ]
When you run mixer you should see
Mixer video is currently set to 75:75
Recording source: mic
So I got my recording source in mixer output.
Also you could try giving the program the actual device /dev/dspW0.1
instead of a symlink.... Maybe it will like that better.
The only other thing I can say on the topic is that many full duplex
cards (I am not at all familiar with yours) can do full duplex but may
only do 8 bit in one direction and 16 bit in the other.
So they may be trying to set AFMT_S16_LE or AFMT_STEREO in both
directions, which might not work. They should be doing AFMT_U8 on
playback and AFMT_STEREO on recording .....
Not sure if this helps you. My only recording interests were to "Tivo"
Radio talk show Mainly Art Bell.
Um. So I just have some crappy program and some scripts. I have not
been played with anything else related to recording.
