@YannikSc which version of PA is that? It should be shown by pulseaudio --version. I've just checked, and the configuration from my gist works on Ubuntu 20.04 with pulseaudio 13.99.1.
It's also interesting you have a six channel channel-map - I though the surround support was only for DTS, can you actually use all those channels?

If you can run PA 14, this profile is already upstream. Even the new pipewire daemon has picked it up, so future looks bright for this headset :-)

Edit: we could also move the discussion of problems with my code to my gist, so we don't confuse the discussion here.

@FennyFatal - thanks for your script, much appreciated!

HWID=aplay -l | grep 'A50' | cut -d" " -f2 | head -1 | cut -d":" -f1

should be changed to:

HWID=$(aplay -l | grep 'A50' | cut -d" " -f2 | head -1 | cut -d":" -f1)

for it to run through shellcheck :)
