pulseaudio example

AppleALC does not support the codec out of the box and I have been unable
to work through https://osy.gitbook.io/hac-mini-guide/details/hda-fix to
figure out how to make it appear. The controller does work, but without
the codec driver support there no soundcard is present to macOS

+PulseAudio for sound (note neither [AppleALC](https://github.com/acidanthera/AppleALC) and varying [`alcid`](https://dortania.github.io/OpenCore-Post-Install/universal/audio.html) or [VoodooHDA-OC](https://github.com/chris1111/VoodooHDA-OC) have [codec support](https://osy.gitbook.io/hac-mini-guide/details/hda-fix#hda-codec) though [IORegistryExplorer](https://github.com/vulgo/IORegistryExplorer) does show the controller component working):
