Subject: [PATCH] CoreAudio: make sure audio stops playing when the device is
muted.
The audio session's category was set to Playback, which implies that
audio is still audible even after setting the device to silent mode or
locking the screen. This shouldn't be the default behavior.
We now set it to Ambient, which preserves mixing with other apps
but makes sure sound is turned off when it should.
