I think the nobara updater works with yum. You should be able to access to the yum update history and find out what audio related packages got installed in the update and downgrade those. Anything with pipewire or alsa in the package name for example
Kernel 6.11 has been super buggy for me. About 3 weeks ago Nobara rolled out that kernel if I’m not mistaken. Do you still have a 6.10 grub option to try out? Since the live usb works that could be the issue.
If all your boot entries are 6.11, boot into the oldest and downgrade that
The official process was a pain anyway, as it required sending personal identification data to China. Anyone that wants a custom ROM on their phone should be looking elsewhere, although I don’t know of any brand that makes that process easy anymore
You could use ProjectLibre although it might be overkill
How would BangleJs be worse in terms of privacy? You can run both with gadgetbridge, so no cloud data necessary.
