This used to work before, but starting a few days ago I can hear no audio when in the Mixed Reality Portal. No sound effects, and no sound from the video and music apps either. Same when launching my own game. I've tried with the "audio in headset" setting both on and off, but nothing seems to change.
I've tried uninstalling and re-installing Mixed Reality. I can hear Cortana during the tutorial process, but the audio cuts off once I get back into the Portal area proper. I've also checked the audio device in the taskbar icon is the correct one, and I've tried to set Spatial Sound both on and off. Nothing seems to work.
I'm on build 16281. Any ideas I could try?
Thanks.
