"Looping" sound not heard when sim is initially launched in Studio Wrapper #561

Test device MacBook Air (m1 chip)

Operating System 12.0.1

Browser Chrome

Problem description When testing https://github.com/phetsims/phet-io/issues/1626 in master, I noticed an inconsistency in sound between the Studio and State Wrappers. In the State wrapper, if I set the state while the balloon is in motion, I hear the associated sound in the downstream sim (as expected). However, if I launch the sim in Studio while the balloon is in motion, the sim launches without the sound. Clicking anywhere on the screen will turn the sound on.

With Mac + Safari, the sim launches with sound on.

As per MK's recommendation, I am not assigning to any developer at this time.

Steps to reproduce In Studio:

  1. Remove Wall
  2. Rub balloon on the sweater to gather a few electrons
  3. Release the balloon far from the sweater
  4. Press 'preview sim' -- the balloon is moving without sound
  5. Click anywhere on the screen--the sound turns on

Tested on Win 11 and I saw something similar to https://github.com/phetsims/fourier-making-waves/issues/217 here. On Chrome I reproduced this. On Firefox I did not.

This is the identical issue as in https://github.com/phetsims/fourier-making-waves/issues/217#issuecomment-1051140400. Closing as a duplicate.
