Bug #11294 is a case where output audio hardware is disabled If the output sound device is disabled or no hardware output device is connected (eg. Windows 10 may disable output audio hardware when no output device is attached/available), then the game should still be playable. We now use the duration of the tracks (in ms) to detect a track's ending. Also isReady is checked for mixer when playing VQA videos (it wasn't before).
