When Ubuntu 20.04 does powersaving, the audio card powers down. When the card powers up again, it emits a short annoying popping/crackling noise, then audio plays just fine. The workaround is to disable power-saving for the audio card, by adding options snd_hda_intel power_save=0 power_save_controller=N to a file in /etc/modprobe.d/alsa-intel-no-powersave.conf and then reboot.
