Summary: allows in-content redirection of audio to permitted output devices (speakers) other than the system default for the user-agent.  The user can achieve similar results with operating systems that provide stream-specific redirection, but some operating systems provide UI only for user-agent-wide or system-wide output choices.

Bug: 1498512

Specification: Audio Output Devices API

Platform coverage: desktop-only.
Implementation on Android is not possible due to operating system limitations.

Preference: media.setsinkid.enabled

DevTools bug: not applicable

Other browsers:

web-platform-tests: audio-output

The intent is to enable on Nightly soon because content-facing aspects are feature-complete.  There is basic browser UI for speaker selection, but persistent permissions and UI around that are still being developed.
