The problem goes away whenever any sound plays, even a completely silent video. There is a solution online that sets two values to prevent the audio driver going into power save state, but the solution isn't permanent and isn't a real solution. That 'hacky' solution uses the following two commands: echo 0 | sudo tee /sys/module/snd_hda_intel/parameters/power_save_controller echo 0 | sudo tee /sys/module/snd_hda_intel/parameters/power_save Power save sounds like a good feature to have, but there should be an option to disable it or something when the motherboard/audio card has high noise levels when it enters power save...
