Participants can lose audio from a Safari user who switches tabs (using WebAudio)

[alhambra1]

What happened and what did you expect to happen?

We revisited and replicated an audio issue our QA team reported internally some time ago -- using the JavaScript client SDK (we tested version 2.20.1), when we set

deviceController = new DefaultDeviceController(this.meetingLogger, {enableWebAudio: true});

which we believe we need in order to use the Voice Focus feature, we see the following symptom: if a Safari user (tested on version 15.0) shifts focus to another tab on the Safari browser, all other participants lose the audio from the Safari user that shifted focus to another tab. Additionally, but not consistently, when shifting focus back to the video conference browser tab, the other participants can sometimes get sounds described as "static" or "robot voice" (possibly related to #1548) (switching the tab a few times on the Safari browser with the receiver on an older Windows laptop, I even once heard only static for the Safari user). The issue apparently does not happen when WebAudio is not enabled.
