In order to get out the problem we can debug the "arecord" program using another program called "strace".
It is tracing all Linux calls of a program. If not already installed in the container instrall strace using "apt install strace" command first.
Then to debug call "strace arecord -l 2>mytrace.txt" and it will be tracing all outputs to the "mytrace.txt" file. After that post the "mytrace.txt" and maybe I can recognize what the problem is. Maybe it is a missing microphone Linux kernel driver, I don't know.
