The humble 3.5mm headphone jack appears to have an enemy in Intel-- a report discovered by AnandTech shows an Intel proposal to "remove the 3.5mm audio jack from audio sources."
But what does Chipzilla have against headphone connectors? First off, is the issue of its analog nature. In technological terms the headphone connector is outright ancient. The original 6.35mm favoured by high-end audio equipment was invented in 1878, while the two-conductor miniature 3.5mm connector has been around by the 1960s. The technology has evolved since then (with the addition of microphone support and remote control) but modern devices require more sophisticated interconnectors with higher data rates.
