[Mac, iPad, iPhone] enumerateDevices does not load audio outputs

[ollyde]

Flutter 3.0.5

Calling this function
await navigator.mediaDevices.enumerateDevices()

Does not produce audio outputs

We have no way to switch audio-outputs for multiple reasons

Think apps that play media (very common)
Apps that do WebRTC
Apps that are music players
Etc

!!! Have not tested on Windows/Android or Web

I wasn't sure if this was a native flutter issue or this library, so also logged it here: flutter/flutter#108874

@cloudwebrtc Wondering why iOS is not here. Does device enumeration work out-of-the-box for iOS?

Thanks.
