Still a thing.

The API itself is a bit stupid as you have to ask access to the microphone to be able to list and change output device, that can be confusing for the user.

Well, Firefox has "selectAudioOutput()" but it's experimental.

From my tests, the reason it happens is becouse the audio input and audio output are coupled together - you can reproduce it quite easily by connecting any bluetooth headphones and toggling between iphoneMic and headphones as an audio source.

TLDR: use audio input devices as audio output devices and modify the tracks as needed. I know it's bad dev experience, but there's nothing that can be done about apple's perpetual autism.

Edit: Bugzilla confirms the results of my tests https://bugs.webkit.org/show_bug.cgi?id=179415
