When a gamer plugged in a headset, the chip panicked. It heard the footsteps in Call of Duty fine, but the microphone input was a muddy swamp of static and the whine of the CPU fan. The chip knew the problem wasn’t hardware; it was language. It was speaking Audio 1.0, but the new USB microphones and high-impedance studio headphones of 2023 spoke a different dialect.
