Thank you for reporting this bug to Ubuntu.
Ubuntu 20.10 (groovy) reached end-of-life on July 22, 2021.
See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases
We appreciate that this bug may be old and you might not be interested
in discussing it any more.
Interestingly, if I run my monitor off my NVidia card, and the audio off
the Intel HDMI, then the Intel audio works correctly. it's only when my
display is connected to the Intel DisplayPort alongside my receiver on
the Intel HDMI that it totally messes up.

note that if I set the output to 7.1 mode, it sounds identically garbled
to 5.1 mode. but if I set it to Digital Stereo, no sound comes out at
all.
