13.4 update includes:
- Sonos home theater products now support decoding DTS Digital Surround.
- A new Battery Saver mode is available for portable Sonos products.
- EQ settings are now accessible by pressing the icon on the Now Playing screen in the Sonos app for iOS.
- An HD badge now shows on the Now Playing screen while Sonos is playing higher quality audio.
For anyone who thinks Sonos isn’t reading these forums or listening to their customers, this update is proof that they most definitely are listening. Thanks, Sonos!

Looking forward to iPhone 13 Trueplay update, Sonos Voice Control and Lossless support for Apple as well as Amazon HD. Might see them this year yet but doubtful. Again, keep it up.
