AudioDeviceUtility::WaitForKey() pulls two characters if the first one is a newline, but discards the final value.
The current code assigns that second value to a local variable, which generates a set-but-unused warning on gcc 4.6.0. Instead, cast the result away. I also refactor the code a bit by adding the right indentation and removing empty lines.
