audio no longer works

[maryz]

I am using the web client to access zoom. I get knocked out of join audio with computer. I can only rejoin once and will get the audio. The button to rejoin after working one time no longer activates. When I try to use the join button the first time, I get the message that browser is prohibing access to the microphone. I don't have a microphone.
I am using google chrome version 109.0.5414.120 , windows 7. I can no longer update chrome.
