I am continually frustrated by the lack of support for DTS HD /MA /X 

A lot of 4K releases have these audio soundtracks and Not Dolby Atmos and although I have the Sonos Flagship Arc I cannot enjoy these movies at their best because I get a message saying audio not supported which then causes me to choose a lower sounding option 

can you please provide an update so that I and many other users can enjoy our media at its best 

kind regards  Roger Stedman
