I see in Autorun under the Driver tab "rt640x64"
Realtek Audio Driver not showing up in Device Manager or Services. Realtek Audio Console says "can not connect to RPC service."

Recently I was checking my audio settings in Windows 11 and I notice the Realtek option wasn't anywhere to be found. I need the Realtek option for the audio ports on my PC. I re-installed the Realtek Audio Drivers from my motherboards driver site countless times and nothing worked or showed up. They seem to be installed in the system, but they don't show anywhere else. I tried to see if my Device Manager showed them, but no luck. I tried watching different videos on how to fix it, but all of them needed to go into either Device Manager or Services where the Realtek Audio Driver isn't showing. I don't know what to do and have tried what seems like everything. The Realtek Audio Drivers install fine and should be working. I have tried using the "Show hidden devices" option, still nothing as well as the "Scan for hardware changes" option. Another problem I am having is with the Realtek Audio console. It gives a message saying, "Can not connect to RPC service." I don't really know what that means. My PC used to be working fine with Realtek, but now it doesn't want to show me anything in Device Manager or Services. I have tried updating BIOS and checking BIOS settings (HD Audio Controller).

Autoruns to confirm that the Realtek drivers are there and confirm the hardware problem because the drivers are not recognized in both Windows and Linux as you tested.
The only other explanation would be a failure with the BIOS and trying to downgrade as you tested by doing an update.

2025-05-23T01:43:18+00:00 What will this autorun do? Because I am still trying to make the Realtek Audio Drivers active and show up. Not sure what else to do. I am conviced it cannot be hardware as it would not prevent the drivers from showing up in Device Manager.

This error is strange, you can check it through Autorun then in the drivers tab in the link below.
