The browser uses the phone microphone instead of the Mac microphone

This behavior is usually related to the Apple ecosystem. When an iPhone is close to the Mac and recognized as an available device, it may appear in Chrome as a usable audio source. The browser may then select it automatically, even if it is not the desired device.

In this case, you should check both Chrome settings and Mac settings. You can also choose to set your default microphone directly in WorkAdventure. It will be activated whenever available for each of your sessions. To do this, go to the microphone settings, click the chevron, and set your default microphone.
