How to update your Sonos speaker to the latest OS and get Hi-Res Audio support | TechRadar
Sonos speakers have been given a hefty upgrade, as the company launches a new operating system and accompanying app that brings support for Hi-Res Audio to its newer wireless speakers.
The new Sonos S2 app also brings a feature called 'room groups' this means your wireless speaker system will be able to remember frequently grouped players (like your bedroom speakers and your living room speakers). This should allow you to get entire areas of your home downstairs, for example playing music much more quickly than before.
