Enhanced Sound option in PhET Menu is not communicated as a checkbox

[terracoda]

While reviewing sounds for https://github.com/phetsims/gravity-force-lab which will have an Enhanced Sound option to turn on a sound for the ruler, I noticed that the menu item, "Enhanced Sound" is not communicated as a checkbox. It sounds the same whether it is checked or not checked.

Since it is menu item, I'm not 100% sure how to do that, but two reasonable options come to mind:

• make it a checkbox, so it is read out at checked or not checked, OR
• make it a toggle button like the Mute Sound toggle button which is read out as checked when toggled on.

In addition, we may need a context response, but not 100% on that either. The checking interaction if communicated might be enough.

If not, we could try:

• "Enhanced sound on."
• "Enhanced sound off."

The same or similar to the Mute Sound toggle button, I think.

Assigning to @jessegreenberg please re-assign as you see fit and have time. Note there are published sims with "Enhanced Sounds", JT is one.

And please re-assign and re-label if we need to do a11y design work for this.

Meeting 11/5

• This is stale, the enhanced sound option is now in preferences.
• @terracoda will investigate to see if this is still relevant with the newer publications of Greenhouse Effect.
• It is now called "extra sounds"
