Sound interrupted on iPad with sleep mode

[Nancy-Salpepi]

On the iPad Air 2 iOS 15.0:

If sleep mode is enabled while voicing is on, when I return to the sim the voicing still works, but no other sounds are heard. However, if I didn't turn on voicing and returned to the sim after sleep mode, the sounds still worked. This was seen on John Travoltage (published and in Master) and GFL:B in Master.

Reviewed with the sound design team, marking as low priority for now since it isn't likely to bother a lot of people and it can be time consuming to track this sort of issue down.
