there is a newer version of this firmware v9.9.5 in the upstream repository,
could you test commit 80cb579614ee576ae74e650fa0b43d9f7c212039
in linux-firmware git:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

It only says "Refine firmware to improve performance." so if it still
does not work upstream realtek should be informed.
