Test Multichannel Audio Output

Tests that multichannel audio output (> 8 channels) is working correctly. This test cannot be run with an offline audio context because it requires an actual audio hardware with the multichannel capability.

Press "Start Test Tone" to run the test. You should hear an one-second sine tone from all the available audio output channels from the channel 1 to the last channel.

Note that this test only works on OSX because CoreAudio driver supports the multichannel streams (more than 2) on a single audio device whereas other platforms do not.
