Mute the radios from the Portal 2 ARG (Transmission Received)
Before Portal 2 was announced, Valve ran an ARG that cryptically hinted at a sequel through an update in Portal. The update added a radio to find every single level, and carrying them all to the end to be vaporized caused them to emit shrieking noises. These noises could be decoded into pictures that seemed to hint at Portal 2, which was later confirmed. Since the ARG serves no purpose anymore, the audio that these radios play to alert you to their presence may be distracting. To mute these radios and achieve a near-vanilla Portal experience, follow these steps.
