I have just retested it with the "aloop", completely without hardware.
The garbled sound comes from the software, from the dmix/libasound.
The problem is not related to (sound) hardware.

I can upload the garbled output which was recorded by "arecord", if it
would be helpful in analyzing the problem. (12s, ~2MB wav.)
