Thanks for the explanations, that saved me a lot of time.

It changed the result a bit. Now, aplay fails, but it takes one or two
seconds before starting ("Playing raw data...") and again one or two seconds
before failing ("Unable to install hw params:..."). In the meantime, the
kernel printed this:

I have attached the full output of amixer in case it is useful. I am
shooting in the dark here. Is there a documentation to understand what all
these settings do?
