To bypass this bug, please complete the following either the Quick OR Manual steps:

Quick steps:

Moot now that the new build is out, but can I assume that this also would have been a solution for the same apparent problem in 15002?  Quite a number of people reported audio cutting out randomly, and I saw it a couple times in the first 24 hours.
Maybe disabling the Spectrum service would work too? From the description it looks like it's something for VR headsets or HoloLens which very few people currently have.

If you can't delete the files mentioned here, you can stop the Spectrum service and try again. No need to reboot.

Also, you can have audio again if you start and stop the Windows Audio service. No need to reboot either.

Not moot at all.  This was written because *it does* apply to 15007.
None of those will permanently fix the underlying issue though.
I only noticed the crashes with the edge settings but  the rest is fine.

I just meant relative to 15002 now that it's obsolete. I was wondering if it was the same issue there or just a similar one.

This solution did not work for me.
likewise on two machines for me :-/
actually after trying a second time it worked :)
