Includes applying the snd_hda_intel.power_save=0 boot option, which gets the HDMI audio working.

• Without this option, audio only works if I boot with the display set to a different input and switch to HDMI at the cryptsetup prompt; booting normally only shows a dummy output available, with all profiles showing unplugged/unavailable in PulseAudio.
• This may not be required in the future, as a Fedora 34 live disk doesn't need this boot option, but Pop 21.04 and mainline kernel 5.12.3 don't fix the issue, so it seems to be required for now.
