Mic input not working in Csound Web IDE

Hi,

I’m trying to run @stevenyi’s Realtime Audio Processing Example in the Csound Web IDE, but the microphone input isn’t working. I’ve tried it in Firefox (105.0.2 ), Chrome 105.0.5195.125), and Safari (15.3), and it doesn’t work. I was expecting to get a pop up asking for permission to use my microphone, but I’m not getting that in any browser. Other Csound projects run fine in the IDE.

I’m on a MacBook Pro with the M1 chip running macOS 11.6.3.

Is this a bug, or is there something I need to do to make this work?

Thanks!
Jason
