Stop audio distortion issue on Linux Mint 19.2 (could affect other ubuntu flavors as well)

1. Open pulse audio configuration file.

nano /etc/pulse/default.pa

2. find a line containing:

load-module module-udev-detect

3. modify this to become:

load-module module-udev-detect tsched=0

4. then run this to kill existing pulseaudio

pulseaudio -k

Why this works?

This disables something called "Glitch-free audio" which doesn't seem to play nice with my sound chip (ALC1220).

Ironic given the name, since it's causing me glitches!
