formulate a plan for how to handle sound with LoL harness

[pixelzoom]

There are at least 3 sim-specific issues reporting that sound doesn't stop playing when a sim is paused in the LoL harness:

https://github.com/phetsims/graphing-lines/issues/116
phetsims/fractions-common#80
phetsims/resistance-in-a-wire#194

phetsims/vibe#33 talks about porting sims from vibe to tambo.

tambo #51 talks about pausing sound playback while a sim is paused.

Labeling with meeting:developer to discuss. Assigning to @ariel-phet to prioritize, assign, and decided what to do about the sim-specific issues.

The LoL harness uses Sim.activeProperty to pause the sim. Could sound be linked to this Property? Then sound would stop in any wrapper using this Property, indluding PhET-iO wrappers.

I see that soundManager already uses sim.activeProperty, so I am not sure why sound doesn't stop in the LoL harness.

That is not yet complete, see #51

Two reasons:
(1) Some (most?) sims are still using vibe and need to be ported to tambo, see phetsims/vibe#33.
(2) tambo does not yet support pausing sound clips, see #51.

@jbphet will investigate after phetsims/vibe#33 but maintenance releases are not necessary after this change.

Marking as low priority since this work will not occur until things have been ported to tambo
