It seems clunky to have to pass in a "bogus" AudioParameters object just to get
to the default values.  Please see my comments in audio_manager.h

+        int sample_rate = parameters.sample_rate();
         // If we weren't able to get the native sampling rate, it most likely
         // means the system did not have an output device, but for mirroring we
         // still want to startup the audio engine, so set reasonable defaults.
