Unable to re-add pcspkr module after using modprobe to remove it
 

(I'm using Ubuntu Jammy Jellyfish with vanilla Gnome).
In an attempt to get the beep command to work, I read on a forum that I could do:

# unload pcspkr module
sudo modprobe -r pcspkr
# add snd-pcsp module
sudo modprobe snd-pcsp

However, now my computer can't produce any sound at all. I think beep works fine now, but I couldn't tell until I tried playing a YouTube video and nothing no matter what I did to the volume.
So, I tried to add it back:

sudo modprobe pcspkr

but got the error:

modprobe: ERROR: could not insert 'pcspkr': Device or resource busy

So, I tried removing snd-pcsp if it was causing the issue:

sudo modprobe -r snd-pcsp

with the resulting error:

modprobe: FATAL: Module snd_pcsp is in use.

So, I checked to see what was installed and what wasn't.

lsmod | grep pcspkr

Returned nothing and:

lsmod | grep snd-pcsp

also returned nothing.
Any advice on how to fix this would be greatly appreciated!

Your explanation of the issue is pretty good however, we need to have more information in order to help you further solve your problem

May I recommend that you try to extract log-files fro the file system hierarchy in the filesystem liisted below.
