Hi, i just upgraded my web meeting SDK from 2.8.0 to 2.9.0 and when i tested it, the blue button “Join Audio by Computer” was disabled.  
i checked the permission and it was already allowed.  
when i check the browser console, there was an error thats not from my application  
i have a screenshot of the error bellow

@mao2x.777 it looks you use 2.8.0 dependency when use 2.9.0.  
you also need update ZoomMtg.setZoomJSLib(‘[https://source.zoom.us/2.9.0/lib](https://source.zoom.us/2.9.0/lib)’, ‘/av’)  
[https://source.zoom.us/2.9.0/lib/av/1502\_js\_media.min.js](https://source.zoom.us/2.9.0/lib/av/1502_js_media.min.js)

ZoomMtg.setZoomJSLib(‘[https://source.zoom.us/2.9.0/lib](https://source.zoom.us/2.9.0/lib)’, ‘/av’);

Thanks
