Upon release I installed W10 1809 on a 2018 MacBook Air (i.e. the most recent one).
Bootcamp audio drivers are v 6.1.7200 (most recent) and macOS Mojave was and is fully up to date.
Even so, video playback is broken and there is no sound, nor does the mic pick up any sound.
In macOS everything works perfectly.
Initially I thought it was something specific to the new device/new W10 version but so many months after release of both, I'm starting to wonder...
Did anyone here encounter this?
There are scattered reports online but no solutions:
