Google will probably have to get the patents themselves removed, by proving prior work or such. Those patents are way too broad.

I wonder what Bose does, they have their own multiroom system. Do they license the patents from Sonos?

> Do they license the patents from Sonos?

IIRC Some other companies made agreements with Sonos to avoid suites (incl apple i blieve?), but sonos has claimed that google was bullying them over a number of things, including the claim that GAssistant only supports one assistant/wake word at a time, per contract, but alexa does not have this limitation. But thats apparently why the android app is worse, they don't support casting, and they're focusing on the apple/alexa ecosystem (airplay, etc).

The major feature the Android app lacks is the "Trueplay" tuning. It relies on a phone to generate and record a sound to map out a room's acoustics, then optimizes the Sonos speaker's output for the room. I've always been wondering if the lack of Trueplay support is due to shortcomings in Android's audio APIs or something like this.

Things like that usually require knowing the hardware characteristics of the device itself as well as some form of calibration range. For iOS Sonos can just buy (or borrow) a couple of iphones every year to generate that data. Doing the same on Android gets a lot harder thanks to the more diverse hardware ecosystem.
