Sound problems on Windows with Boot Camp
Before we start, make sure to have a working internet connection, and also take backup of all the files on your Windows 10 to either external drive or on the Mac using the inbuilt explorer.
Update to the latest version of Boot Camp
Rule of thumb always has the latest software on your PC. In case you haven’t updated your macOS, which also includes Boot Camp software, make sure to download and install it separately.

Install the drivers from Apple’s website In my opinion, this is preferred as a way to make sure to download the latest audio drivers from the website. However, it’s going to be tough hunting down the driver.
Go to Apple Support website.Search for the audio driver based on OEM nameOnce you have it, run the program, and install it.
