No audio Zoom only

I can longer hear the audio on Zoom calls and only on Zoom. All other audio works on my PC. When I bring up the Zoom audio settings the correct speaker is selected but I run thru the 4 selections that are there which includes the speakers (listed 2x), audio card and microphone. When i press test speakers the meter bar reacts like there is sound but there is none. Again I get all other sounds. Music play, notification sounds. I was also on a Google Meet today without a problem. Only Zoom and all the settings I see appear to be correct.
