I´m using a Home Theater with Realtek ALC892 card from my Z97 motherboard With windows 7, all fine. In windows 10, to play a mp3 using Media Player or any other player, subwoofer works only when i swap center channel using Realtek tool. However games, for example, i´ll lost 5.1...and vice-versa. I tried latest driver from windows update and realtek site...same problem. Any ideias?
Have you tried uninstalling the Realtek driver and using the default Microsoft one instead. Realtek gave me trouble on both of my notebooks until I got rid of it.
