(Please don't top-post.)

If you record from the alsa sink while this motor-boating is happening,
is the audio in the recorded file fine? You can record with for example
this command:

     parecord --device=NAME_OF_THE_MONITOR_SOURCE > ~/tmp/test.wav

Replace NAME_OF_THE_MONITOR_SOURCE with the name of the monitor source.
You can list the available sources with "pactl list sources short",
hopefully you're able to figure out which of the sources is the correct
one (it's one of those that end with ".monitor").
