USB Microphone cutting out during voice chats

Everything is out of mind
Because every time during a voice call it complaining that their audio from the microphone that is being cut out forcing them to end the call and restart it
It usually happens around the ~10 minutes… I think that restarting the windows audio service. is the best advice…

Some info on the machines, they are HP G5s running Windows 1809.
I have attempted the troubleshooting Uninstalling and reinstalling the driver, updating the driver,
trying different USB mic devices,
I attempted AudioEndpoint.inf from my machine and force theirs into using that one but was unable to install it because it is “not digitally signed”.

I ma deeply stuck here…
Thus anyone can help me…
Who can solve this issue…

Thanks a lot
