We've got a fleet of Dell Latitude 5285 laptops, all of which are having an issue whereby the Cisco proximity application says "Your microphone is not working" even though you can see the audio levels go up and down on the microphone in the "recording devices" window.
My understanding is that if this was an issue with frequency range, the app would work but we just couldn't pair with anything, whereas in this instance the "microphone not working" error comes up immediately, it doesn't even try and pair.
Tried different drivers, BIOS update, Cisco Proximity 2.0.7 and 2.0.8 and installing Proximity straight from a fresh Win10 installation but no change.
