Steps to reproduce:

1. Log in to http://fmd.dev.mozaws.net/
2. Press "Play Sound" (and cover your ears).
3. As ear shattering tone plays on your device, swipe the phone to unlock device.

Actual results:

Even after the phone is unlocked and you're staring at the homescreen, the shrill keeps playing.

Expected results:

After the user swiped to unlock the phone, we should stop that infernal tone.

Workaround:

Mute the phone, which is suboptimal.
Even with device volume muted, it doesn't seem like the phone vibrates when you attempt to play a sound (which is probably a separate issue).

This is a FxOS client side issue. Will you throw down some bugzillas for both the sound not stopping and the sound not playing when the device is muted?

I'll close this silliness since I filed both of these upstream as they look like b2g-isms.
