Hi Delia,

Thanks for the report.
Whenever echo cancellation is turned on, Safari will duck the other processes.
This is also happening whenever doing a call through FaceTime.

If you do not want that, you can disable echo cancellation through constraints when doing the getUserMedia call. No audio ducking should happen at that point.

Should you want later on to activate echo cancellation (for instance when call is on), applyConstraints might be used to enable/disable echo cancellation whenever needed.

You are the assignee for the bug.
