Samsung Galaxy Book2 Pro 360 - No sound from speakers (Bluetooth headphones work)

Hoping someone can help with this. I have tried to no avail to get my speakers to make any sound. I’m running Fedora 37 Workstation.

I tried following these instructions which some have reported worked for the Galaxy Book (not the Book2) in Manjaro and Arch Linux but they didn’t work for me.

Any help would be greatly appreciated!

FYI the problem is also present with a Book2 Pro (Realteak ALC298) under Linux Mint 21.1 even using the new 6.1 mainline kernels up to and including 6.1.12.

Should be similar to this problem on another system with the Realtek ALC298 sound card
