I have installed updated audio driver - Realtek HD Audio Driver dated 2021/10/05 from motherboard download page.
The process is smooth and the PC restarts twice to delete old driver and install the new one. The installation guide told me that the process is complete.
However, after that, I note in Device Manager Audio inputs and outputs category, the driver remains the one from Microsoft dated year 2019.
Do you have any idea?
Try opening the device in Dev Manager, from Driver tab choose Update driver, then Automatically to see if it picks it up from downloads. If not choose Update Driver > Browse > Let Me Pick to see if it's queued there. If not Update Driver > Browse to the download location where it's Unzipped.
Tried all methods, still no change for audio driver.
Should I proceed with updating of other drivers?
Yes, go ahead.
