Microphone test failed.

What is the expected behavior?

rec test.wav should work, and arecord -l should output the record devices.

What behavior are you observing?

When I run rec test.wav, the following errors were output:
ALSA lib pcm_hw.c:1713:(_snd_pcm_hw_open) Invalid value for card

Hi @bill-lzb,

Could you print the output of the following commands?

arecord -L
cat ~/.asoundrc

I am looking at https://www.raspberrypi.org/forums/viewtopic.php?t=13088 and some of the posts there might fix this particular problem.

Thanks,
Fede
