This is not ideal but not a regression. Alison, can you take a look at this please?

I tried and found that the sound will stop when screen off, sound will play when screen on (even screen lock).
I check with iOS and android, and both of them will stop sound when screen off and screen lock.

Hi Gregor,

I am not sure who is the suitable person to check this issue, could you please help to dispatch this bug? Thank you.

I guess the question is which app is allowed to play music even if the screen is off. You want the music app to play music in this scenario for example. Blake, any idea how to solve this issue? Do we have anything in the audio api that helps here?
