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.
Solved! Go to Solution.
Looking at other posts here - it looks like maybe this is because the Dell laptops only give 4-channel options for sample rate, whereas Cisco Proximity only supports mono and stereo?
Does anyone know a way to introduce mono or stereo sampling formats to a microphone in Windows where it's not in the defaults?
Sorry for the belated reply. I'm sorry to say the release won't be for at least a couple of months, unless priorities change. If more people and large deployments are experiencing this, please report here.
We have the same issue with our 7285 2in1 (K17M001) as well as the new 5290 2in1 (T17G002) machines. A new release would be highly appreciated since those models don't have a miniDP port again and proximity would be very useful for those computers.
When will the next release be posted to resolve this issue with Dell laptops and Proximity?
We are now waiting since half a year for a release that includes this fix. Very disappointing specially since Cisco has a fix for it but just does not release it.
I tested out the 3.0 release today and Proximity is still not working. I have the 5290 2 in 1s from Dell. I'm no longer getting the microphone error, Proximity see's that there's one there, it just doesn't find the system. I've tested 3.0 on regular laptops and confirmed 3.0 is working on those. Unfortunately this doesn't seem to fox the multi channel microphone issue.
