Actually no, the video I'd had up just didn't have enough on the high end to notice the distortion. But clicking on the icon for the script I made to reload pulse audio does seem to have fixed it again. So yeah, turns out making a .desktop file is pretty straight forward. I just made a text file with the following: [Desktop Entry] Encoding=UTF-8 Version=1.0 Type=Application Terminal=false Exec=bash /home/steven/.scripts/RestartPulseAudio.sh Icon=/home/steven/.scripts/High-contrast-audio-volume-high.svg Name=Restart Pulse Audio Downloaded a speaker icon to use for it and put it in the same directory as the RestartPulseAudio.sh file and that was that. I suppose I should just set that script to automatically run at startup.

Well.
