A new update for Xbox OS went live April 19 for Xbox Update Preview users, and it will soon add two small but important features to your favorite Xbox console. The update adds a new audio feature and makes a helpful addition to Quick Resume.
First, the update will add audio passthrough to the console, meaning that audio will “pass through” the console with minimal effect. While the specifics of digital audio can be complicated, in layman’s terms, this basically means that the Xbox will pass the audio on to a receiver with no processing or effects. This means that your Xbox can pass the signal onto your receiver, which will allow for a surround sound or similar setup with less cables than usual.
