Error Code C10121-0 on Acer headset
Gone through all the installs, got mixed reality working - until I plug in my Acer headset on my Samsung laptop. Mixed Reality churns, then says "we couldn't start Windows Mixed Reality". Mixed starts fine on my Acer s7 (though incredibly slow). Could this be video drivers? On startup, mixed reality goes to black screen a couple of times, then stabilizes. I have USB 3.0.
