It's an infinite loop. Repeatedly pressing CTRL-C should stop it or
else killing the bash process from another terminal.

Well Control C is one of the first things I try, perhaps I should have
kept trying longer? When I found no remedy in my notes I was beaten and
had to reboot.
You have to hit it fast enough in a row that you kill the aplay and then
the bash script before it starts another one. The easier method is to
just kill the bash script from another terminal. Sometimes another
option is to use ^Z or kill -STOP the process to give you time to catch it.
However aplay will not work after that episode. I can see the audio
signal with the pulseaudio meter bar and Thunderbird still signals
received mail via aplay, but other things where I used it produce no
sound in the loudspeaker. Aplay in a terminal produces no sound, so I
guess the loop still runs and audio is being muted from it. Nothing I
tried in PAvolume restored it, I will try anything suggested now.
If you rebooted, then the runaway script is gone and won't be affecting
anything. I'm confused how you say some things can run aplay and make
audio, but you can't run it directly.
