BBB - Audio Cape - BB-BONE-AUDI-01 - can play, but can't record

Hi All,

I have purchased a BBB pre-loaded with Debian and have the Audio Cape BB-BONE-AUDI-01 running.

I believe the BB-BONE-AUDI-01 works because I can run aplay on an audio file created locally with Audacity.

Works:

aplay SC_TC_01.wav

Error: Records only static
arecord -f dat -d 5 -D hw:0,0 test.wav
aplay test.wav

I’ve run alsamixer and have made sure nothing is muted. I believe my results from unmuting have made the static somehow worse.
alsamixer

The audio files are being created and have an audio length of 5 seconds.

All I hear is some static from the recording. Nothing else. Can someone help me?

I’m not sure if I configured the Audio Cape wrong, but I figured if ‘aplay’ can play an audio file then in theory it should work from the HW side. I didn’t know if there is additional hardware changes or if I’m missing something else.

Your help is greatly appreciated. Thanks in advance.

Hi All,

I have used the following commands to make sure the correct things are on. The issue still persists, but now I don’t hear any static.

I’m attaching the amixer contents.
