Proximity not working appears to be microphone related

[scutp]

Got an error code below. Have had an issue with proximity using the microphone. I clicked on the learn more. 

See file proximity 3.0.4.JPG. 

Unknown error code: 0x80070005
Platform: Win

Function:Initialize

I then tried the latest installation and got the following error code

unknown error code: E_ACCESSDENIED

Platform: win

Function:Initialize 

I have since rolled back to 3.0.4. Is there a fix for this and what are the likely causes?

Laptop is a HP Elitebook 830 G6. Using Windows 10

Probably another app is using the microphone, or there is an issue with your audio device. If other applications are using the microphone, you could try quitting them to debug. There are some images under https://proximity.cisco.com/help/?platform=win&code=AUDCLNT_E_EXCLUSIVE_MODE_NOT_ALLOWED that detail how the default microphone recording settings look on Windows. You could try to uncheck the “Give exclusive mode applications priority” checkbox as well, to see if that helps.

Hi mneergaa your post actually helped me, I ended up I reloading the OS on the laptop. There was definitely something stopping the software from working.
