To reproduce:
1 - Open PathWind (or any other app playing sound)
2 - Lock the screen and wait 5 seconds
3 - Press power to resume the device
4 - With a passcode/passphrase set, try unlocking the screen. You'll see the game will resume after swiping the greeter, and not after fully unlocking the device with the passcode/passphrase.
