"Windows x64 driver (Rtkvac64.sys) not found!" Solved/Closed

Question

Hello, I reset Windows 10 because my PC was lagging horribly. I then restarted it, and all the deleted applications were in a Microsoft Edge folder on the desktop. I reinstalled all the deleted software except for the NVIDIA drivers, which are present by default.  For the audio, I had to install Realtek and AC'97 Audio. Realtek didn't cause any problems, while AC'97 Audio told me: "Windows x64 driver (Rtkvac64.sys) is missing!" So I looked for Rtkvac.sys, installed it, and placed the folder in Windows->System32->drivers and left it there thinking it would solve the AC'97 Audio problem.  https://img-19.ccm2.net/pADvpMAz_WxIpLDgVgJrAxgZjI4=/1e2a417b111d4123a2c50449ebea30c5/ccm-ugc/Capture.PNG  So here I am, and I'm trying to solve this problem. Tell me how and where to place Rtkvac64.sys.  Thank you in advance!  -Flash_

Hello,  Your motherboard has an IDT audio chipset, not a "Realtek AC'97". The driver won't install because it's incompatible.

Hello,  Press Windows + R Type --> devmgmt.msc and OK.  If there is an alert regarding audio: Give the hardware ID number of the device It’s a number that should look like this as an example: --> PCI\VEN_1969&DEV_1026&SUBSYS....... If needed, check -->  here Post the number in your next message.  What do you have under audio, video, and game controllers?  What is the brand and the exact model number of the PC?   -- The human being is at their best when things are at their worst.

The PC number is 500-457nf and the brand is HP Pavilion. Thank you for your response, but I have 3... things I guess in Audio, Video and Game Controllers. There is IDT High Definition Audio, NVIDIA High Definition Audio, and NVIDIA Virtual Audio Device (Wave Extensible) (WDM).  Let me know if I should send all three or just one.  Thank you in advance!

Hello, so what do I need to do/install? Thanks for your comment! -- Flash

kaneagle · Answer

The IDT audio chipset is properly installed along with the HDMI audio, so there's nothing to install for audio, forget the Realtek.  -- Human beings are at their best when things are at their worst.
