Standalone (Mac): No audio if sound card doesn't have an input jack

[martinfinke]

When I run the standalone (APP target) on a MacBook Air (which doesn't have an audio input jack, just a microphone), it doesn't start an audio stream (so there's no input or output). The reason seems to be in app_main.h line 34:

#define DEFAULT_INPUT_DEV "Built-in Input"

It's trying to set the input to something that's not in the hardware. Changing this to "Built-in Microphone" solves the problem on my MacBook Air. After changing it, you have to delete ~/Library/Application Support/ as well.
