Several days ago the audio in/out (mic + speakers) stopped working on the Hololens. I can't reach Cortana ("Hey Cortana" results in no effect) and I can't hear any Windows sounds (i.e. bloom sound when popping up the start menu). The volume meter always showed "0", no matter if I pushed the volume buttons on the head band.
Besides that, everything was fine. But a Hololens without speech input and spacial audio isn't a full Hololens, is it?
So, after not finding similar reported issues on the internet I decided to do a factory reset.
Done. And .. Oh noes!! After having that finished, when first starting the clean device it tells me:
Adjust your device to see all edges.
Say "Next" to begin.
But the mic still doesn't seem to work :-(
My "next" speech command doesn't reach the Hololens.
I also tried recovery with the Windows Device Recovery Tool as recommended here.
Is there any way to go on with the initialization process without speech? (keyboard ..?)
Any idea what I could do to at least overcome the initialization?
