I have been experiencing this problem for a time now.
No necessarily restricted to Fedora 32 which is my current operating system on use.
The failure happens without notice and under no specific circumstance.
Use of no special program.
But, I have observed some possible constants.
Use of some multimedia programs like YouTube, Rythmbox, Zoom.
When halting, sound enters in an infinite loop reproducing a fragment o audio.
When on other programs like LibreOffice or email the pointer simply stops.
Only solution is to hard reset.
