No Audio in Teams Again

Our boardroom Zoom Rooms system has been automatically updated to version 6.0.7 (4157) , 64bit. Since then, far end participants are unable to hear the people in the boardroom. We have a Crestron professional AV system with Zoom Rooms installed on Windows PC appliance (NUC). I had to manually downgrade to version 5.17.9 (3926) as downgrading from device management from Zoom portal does not have this version.

I opened a ticket with support (request # TS1273108), but they are just useless, so hoping can find a solution here.
