Re: [Alsa-user] New user with an ICUSBAUDIO7D
OK, arecord -f S16_LE --channels=2 --device="hw:2,0" --rate=44100 junk.wav does work. It's not pretty, I have to amplify in Audacity about 40 db. My coupling capacitor seems to be leaky, I see DC on the waveform and I get some motorboating. But I did it twice and both times worked. What I did for a signal was just wet a finger and touch the center conductor of the soundcard input, which captures hum. I did a pattern of touching it and not touching it, what I see on the screen roughly matches what I did. So I need to build more amplification.

Re: [Alsa-user] New user with an ICUSBAUDIO7D
When I do arecord -f S16_LE --channels=2 --device="hw:2,0" --rate=44100 junk.wav It doesn't complain but the recording is silence. Something may be turned down or off in the mixer. Or I'm recording the wrong subdevice. hw:2,1 and hw:2,2 don't seem to be found. If I amplify (40 db) in Audacity there's not really anything there. I'm using a bare electret cartridge with a 3.9 k resistor from 4.2 volts in from a lithium cell, and a 1 MFD coupling cap. I'd expect to see something when I tap on it, but nothing.

Hmm, none of these are 1 channel. I do want 2 channels but so far I've got 1 electret cartridge on prototype board trying to figure out how much amplification I need.
