Summary: arecord gives silence
Description:
IBM Thinkpad T21 with Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion
Audio Accelerator] (rev 01).
alsamixer correctly mixes the inputs over to the line out (I can hear
microphone in and line in successfully mixed) but arecord gives silence.
I've tried using a usb soundcard on the same machine, and everything works
fine there, so I think this is only the snd-cs46xx driver.
I'm not sure what other info is useful - please let me know. Thank you.

cat /proc/asound/pcm
Try the following test and post the output including the setup line output
by arecord
arecord -v -Dhw:0,0 -f cd test1.wav
arecord -v -Dplughw:0,0 -f cd test2.wav
arecord -v -f cd test3.wav
