[NEW Use Case] Pinning audio output

[RealJoshue108]

(Filed on behalf of @JaninaSajka ) We need to discuss whether it's time to call out the possibility of pinning audio output from multiple portions of a screen, perhaps routing those to multiple audio devices, to different TTS engines, and/or with different voice settings.

We have multiple use cases for pinning something making the ability to identify something atomic and invoke an architectural mechanism to communicate that specific item a kind of generic requirement.

Similarly, we may have several items destined for different TTS engines and different audio output devices.

Relates to w3c/apa#97

NOTE: This may also relate to the pinning of the braille display - or a mix of pinned braille and audio outputs. This may also involve routing to TTS engines, and/or with different voice settings.

Discussed by RQTF on 9th Dec https://www.w3.org/2020/12/09-rqtf-minutes.html - may require support from on RTC API. To be left open and discussed in new year.

@JaninaSajka we may need a footnote to reflect usage of the term pinning.

@jasonjgw so what are the use cases: audio, braille, routing - being able to dynamically route audio, pinning of status messages, who is the last speaker, here is the last message,

What are the atomic pieces of data - who is speaking, what just popped up, etc.

@joshueoconnor we will need to define what atomic is and how the term relates to pieces that the user may wish to be able:

NEW REQ (draft) 1d: Atomic pieces of data such as person currently speaking, people entering or leaving a meeting, or the last message posted in the chat channel can be pinned to a user interface.

There could be a new requirement for multiple sign language translations in an application.

@joshueoconnor to ping @nitedog and Wilco, to see if EM/ACT has definitions of atomic we can use.
