So I finally managed to upgrade from 8.1 to 10. All seems well bar afew issues. My mean 1 being my surround sound. After the upgrade I can only use 2 channel audio, if I set my audio to 5.1 I get zero sound and if I press test I get an error 'failed to play test tone'. I know its early but this is a big pain to me. Is there any fix's Always 1 of my Bluetooth adapters has stopped working and I cant get my ps3 OR ps4 controllers working, but that's for another day ha my audio is from my motherboard Z97 pro wifi ac and its hooked up to a sony amp over optical Everything was working fine with 8.1 so its definitely win 10 to blame. I have a similar problem, setting sound to 5.1 freezes the computer.

Everything OK on stereo (2 speakers). I downloaded the new drivers from my motherboard site and from realtek. The problem was still there on both cases. So I set the sound to 7.1 and disabled the rear pair of speakers. It works for now. I don't know if I'm losing a part of sound, but it's enough for me.
