v1.9.0 breaks microphone support

[alopix]

Use AudioConfig.fromDefaultMicrophoneInput() as the audio config for a connection and try listening once. It will crash with something like

Error: Uncaught [TypeError: Cannot read property 'send' of undefined]

Works fine in v1.8.1 but is broken in the recently released v1.9.0.

I believe the PR #126 addresses this.
