No not a part of the OS and als no idea why they used python, that script is full of crazy functions so may be needed.
I translated the python 3.12 to 3.9 using ChatGPT lol, as even after installing up-to-date python and placing it in my home $PATH the script threw errors.
I think it worked, but there is an issue with my atomic system, so I likely need to build an RPM for the changes or use a different command for akmods or package the kernel myself or whatever.
I'm not familiar with bootc based systems but it looks like you could hack up the container spec here: https://codeberg.org/HeliumOS/bootc to build heliumOS with those changes. You would then use something like bootc switch ... to use it.
(Add a line in the docker file to install newer python and run the audio script. I'm not sure if the script requires changes for this.)
I could be way off base with this idea, I'm not sure how heliumOS expects users to install packages.
You may also be able to run the latest python docker image to run the script, but the way this script modifies system files shouldn't work on an immutable system.
