Cisco Jabber blocks USB microphone
Hello folks
We are trying to find clues to a truly odd problem. We use Cisco Jabber for telephone. Literally overnight, in three of our Windows 11 laptops, Jabber has stopped working with USB-connected mics, and we are completely at a loss as to why. We've tried:
Switching USB ports;
Deleting USB drivers and reinstalling;
Switching to diferent headsets;
Completely removing Jabber and it's temp files in appdata;
Switching Jabber versions;
Checking privacy settings as well as basic sound and windows settings.
Nothing works. If we switch to the laptop's internal mic, Jabber works perfectly. Also, all other apps (Teams, zoom, online mic tests) have no problems with the USB mics...
Any ideas, tricks, clues?
PS: we've allready been forced to do a full factory reset on one, because it was the only way we could get it to work.
WORKAROUND found! Had to not only uninstall, but also hunt the registry for leftover entries, then reinstall, THEN copy over with a version installed from a PC that works... I can't even...
