Public bug reported:
# Description about OS and package →
Description: Ubuntu 20.04.2 LTS
Release: 20.04
alsa-utils:
Installed: 1.2.2-1ubuntu2.1
Candidate: 1.2.2-1ubuntu2.1
# What expected →
Sound which plays after inserting a USB drive/any other sound made by OS while
using a VM will play normally.
# What happened →
Actually whenever I plug my USB drive while running a VM, there is a sound of
crackling/scratching when the USB drive is plugged-in and this also happens
when the VM makes a sound of login or anything else, and also that the strange
distortion only comes at the end of a sound. What could be the possible reason
for this?
