Sonos now supports Amazon Music’s Ultra HD and Dolby Atmos tracks
As it previously promised, Sonos is today rolling out support for Ultra HD and Dolby Atmos tracks from Amazon Music Unlimited. After downloading the latest system update for their Sonos speakers, Amazon Music subscribers will see new badges on the Now Playing screen that clearly identify the quality of whatever music you’re playing. Sonos already supported CD-quality HD tracks on Amazon Music, as it does for other services as well.
These new badges will show either HD (lossless 16-bit stream), Ultra HD (lossless 24-bit stream), or Dolby Atmos. Sonos notes that for lossless music, the maximum sample rate supported is 48kHz.
