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.
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.

Sometimes doing something like
killall aplay
A few times will put an end to things running away from you.

No, that would only kill the aplay and then the shell script would
immediately start it again.

Of course, I was forgetting it was in the middle of a script. I was
thinking of a command going nuts.
Surely just closing the terminal window would have killed that?

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

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.

Yes, confusing to me too, I try only to query when I reach the end of my
limited skill set.
It seems to me like a path through Pulseaudio is broken. I will go back
and try again with all I have there, the pavolume GUI. Will report back
if I find anything, day just begins here ...
Thanks all for the suggestions, Bob

Well, I still have this annoying problem but after my effort yesterday
it appears there was a few errors in my description.
The Thunderbird notification does not use aplay, it just gets the file
and path: "file:///home/bobg/apps/audio/login.wav"
And when J aplay that same file PSvolume does not show the metering bar,
it is only showing in text that it is "Playing .wav" on the "Playback"
input and the same text on the "Output Devices" sound while nothing is
heard from the loudspeaker.
So it seems that aplay has simply stopped producing output. Other audio
sources still work as expected e.g. Thunderbird and VLC both produce
sound. Aplay from a terminal does not.
I tried "# dnf reinstall /usr/bin/aplay" and it installed "alsa-utils"
which presumably contains aplay, that made no improvement.
I am still open to suggestions, Bob

The vvv is important, because it provides more information, including an
output profile over time, a rough vu meter. That is, it will show if
aplay is actually sending output to the device.

hat's itnteresting in that when I feed aplay a tone, only happens in
this computer, the volume begins low and increasesover a second or two,
very noticable but not a problem I was bothered by.

Yes I keep seeing that, looks like the
connection between aplay and
Polseaudio is open ...
Can you check in pavucontrol that the default device is actually your

cat /etc/alsa/alsactl.conf

The essential
ones are OO and up to the red, "L{NE" was muted I set to
MM and turned the level up, that does not restore the sound though.

I'm stumped. Everything says you should have sound from aplay.
aplay is producing sound.
It's sending it to default, which is sound device 0.
Sound device 0 has output enabled, and volumes turned up.
Other sound plays through default and pulseaudio.
A long shot. Check in pavucontrol whether the default device in
pulseaudio is set to be device 0, the analog card, and that it is
enabled. If that is true, I'm out of ideas. Everything says you should
have sound.
