Intermittent CTI microphone permission denied errors,Agent staus changed to not ready and Audio issues on zoom lightning CTI

User is trying to use the Zoom Contact Center Salesforce CTI integration and is blocked by intermittent "Permission denied for Microphone" and missed inbound calls while handling chat.Noise issue also Audio issues  happening like ,could not hear the customer and he could not hear me as well (Only after a couple of minutes into the call). The customer's voice sounded robotic. . When an agent is actively handling a chat and an inbound voice call is presented, the agent sometimes does not hear the incoming call ringtone. Shortly afterward, the following error appears: “Permission denied for Microphone” The call is then bounced/missed, and the Salesforce/CTI screen refreshes automatically. The agent's headset is connected before the start of the shift, and the required microphone permissions have already been verified at both the browser and operating-system levels. The issue is intermittent but occurs approximately once a week and is impacting agents' ability to receive inbound voice calls while handling chat engagements.Please find the below screen shots for your reference.Any solution for this?Did you guys face this type of issues?
 

Thanks,
