You can pause the continuous speaker membrane at any position, and when you resume playing, it may not trigger a sound depending on the membrane position.

Discovered in #510, you can pause the continuous speaker membrane at any position, and when you resume playing, it may not trigger a sound depending on the membrane position.

I think I saw what @samreid mentioned in #510 (comment). If you stop a wave at as the sound starts, it can mess up the sound when it starts at a new frequency. I have had the wrong frequency start then fix itself, or the sound take a fair amount of time to start.

I just noticed that this seems to happen in phetsims/qa#580, so it is unlikely to be related to the fix for #510

This does not feel blocking to me, @arouinfar what do you recommend?

[arouinfar]

Nice find! @samreid I would agree that this is not blocking. At worst, the speaker membrane sound is missing/off for one round which doesn't seem particularly serious to me.
