Lenovo Yoga 9 Pro 16IMH9 - Type 83DN Audio issue

Hello,
So I picked up the above laptop about a month ago, and have been looking to maybe use Fedora on it for my daily driver. I

The audio subsystem suffers from a variant of the same issues mentioned in 217449 – Bass speakers not working on Lenovo Yoga Pro 9 14IRP8 to combat that, I have implemented the same fix as described here Sound is very low and missing mid/bass frequencies · Issue #2 · karypid/YogaPro-16IMH9 · GitHub but is there hope for a longterm fix? Since this is just a new variant of the multi amp bug, should I file a new bug report?

Any suggestions?

This is 2 separate issues with 2 different possible solutions.
First is audio and second is screen brightness. The GPU drivers do not manage the screen brightness so the nvidia driver is not the problem.

Please separate these issues into 2 different threads so each may be addressed appropriately.

I am not an expert in either so cannot provide useful suggestions other than this one.
