Can the microphone mute button of AVerMedia speakerphone sync with my video conference software? I can reduce background noise using Microsoft Teams or Zoom. Why do I need the speakerphone's AI noise reduction function? What can AI noise reduction do? How do I set my speakerphone as the default audio device on my Mac computer? After connecting with my Windows PC, how do I make sure that there is audio in the AVerMedia speakerphone? Do USB extension cables (> 2M) affect sound quality? Can AS311 support Zero Client/Thin Client? What is the feature of Hotkey on AS311?
