Bought several U500-H machines for enterprise use. Upon installing our corporate image, Windows did not automatically detect the Realtek sound card. I had to comb through the Minisforum default image and extract the audio drivers. I have placed them in a public GitHub repo that can be found here: https://github.com/julian1059/minisforum-drivers . Check out the README for install instructions since there is no executable. Hope this saves someone some time.
