I got the Windows 10 Pro Insider Preview 17074 update today and thought I'd share a few screenshots of the new audio settings screens since eventually these changes usually make it to release. Using the Realtek onboard audio with the 5.1 option enabled and the Creative Blaster X-Fi MB5 software running on my GA-AX370-Gaming K7 . I have the front speakers set to small, center / rear speakers disabled and the sub output boosted. Everything seems to work well. I didn't have to reinstall my software when I upgraded. The first link above details all the changes that happened with the update. The old sound control panel and properties windows are still there; you just have to look in the new menus to find them. Enjoy!
