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%.
