Hi, DId you try the DDU process? I'm trying rignt now because of a similar issue (most of version of realtek driver just uninstall something, get reboot and again uninstall something instead of just continuing the installation, in some point stop uninstalling but never continues to intallation).
I have sound but I can't activate the front panel because this thing is not giving me any option for realtek audio manager.
I already tried processes with device manager (uninstalling, reinstalling, update) and nothing fix it.
Finally I used DDU, no internet connection, reboot, install driver (6.0.9.235.1, this version installs different and doesn't request reboot or uninstall or something else, it just install apparently). Now I tried again looking for the realtek audio manager and nothing. The apps and features show the program but device manager shows something like... the default audio driver. I'm completely bothered right now.
