Sound tab crashes on Mac Safari + bluetooth headphones + google hangouts #5524

On Mac Safari, we're seeing a crash if you're using bluetooth headphones, you have a google hangout running that is accessing your microphone, and you switch to the sounds tab.

To repro:

turn on bluetooth headphones
- On Mac Chrome:
Start or enter a google hangout with microphone enabled. The preview screen (before you have joined the hangout) works- it accesses your microphone and shows a little green audio indicator in the bottom left.
- On mac Safari:
reload Scratch site and create a new project
click on the Sounds tab
you will see BSOD

We're seeing a console error containing: Unhandled Error: createBuffer@[native code] and [Error] NotSupportedError: The operation is not supported. createBuffer

Operating System and Browser

Mac OS 10.15.2 Safari 13.0.4 also: Mac OS 10.14.5 Safari 12.1.1

notes:

I was able to repro the bug as before, now on MacOS 10.15.6, Safari 13.1.2
Projects play sound on the project page, but not in the editor (!)
Clicking a play sound block gives an error
Sound editor crashes as before
Bug occurs with either an active google hangout, or an active zoom session (using the zoom client app)

More notes:

The first error I see is from the startAudioContext module
That module has been "archived" and not updated in a few years, but it's not immediately clear why. Is it obsolete? No longer necessary?
We use startAudioContext in scratch-GUI and scratch-audio (maybe other places too?)
Maybe the problem in scratch-audio causes the blocks not to play sounds, and the problem in GUI causes the sound editor to crash. It's not clear if the cause in either case is startAudioContext or some underlying problem
okay... so disabling startAudioContext in both GUI and audio does not prevent either problem...

Please change your title. Mac ≠ macOS.
