But I have a mic and recorded sound in mine. I tried your conf and the hw:0 version of your conf. And both worked on my setup. Perhaps you have some other syntax issue in the asoundrc. Try moving that part to the top to get it interpreted before it runs into an error that stops it from interpretating. (just guessing though, any missing { { { or } } }'s?)

In either case you probably want to stop any sound daemons that might be running interference. Also check your alsamixer settings. Make sure the mic / capture isn't muted. And otherwise exists.
I renamed .asoundrc to .org, killed artsd and tried:
arecord -d 10 -f S16_LE -r 48000 -c 2 -t wav -D hw:0 foobar.wav
but I still get:
$ arecord -d 10 -f S16_LE -r 48000 -c 2 -t wav -D hw:0 foobar.wav
Recording WAVE 'foobar.wav' : Signed 16 bit Little Endian, Rate 48000
Hz, Stereo
arecord: pcm_read:1347: read error: Input/output error
("-c 1" gives a different error).
Alsamixer seems odd to me:
- "Mic" is showing "L R, CAPTUR" but has no percentage bar
- "IEC958 P" is showing "L R, CAPTUR" but has no percentage bar
- "Capture" is also showing "L R, CAPTUR" but has the percentage bar at
100%.
