Is there a way to feed multiple audio interfaces with Web Audio?

Question

I am currently thinking about how to realise an app that feeds multiple audio interfaces with different sounds. For example if I have a second sound card at disposal.

As far as I researched the AudioContext of Web Audio only feeds a single destination. I haven't seen a way to select the actual destination hardware.

Can anyone think of a way to work around this?

Answer 1

Nope. It'll use whatever your system default is.

Answer 2

You can output audio from an audio/video element to a specified output device using setSinkid()

videoElement.setSinkId(deviceID).then().catch()
