Righto, thanks. If I was playing blu-rays/4k disks with DTS, would I still get sound with those settings? I'm aware the Beam doesn't support it so I'm stuck, just curious what's the best to do. It's not really an issue if I have to change it every time, just obviously preferable if I don't have to.Not at my PS5 to check, but you'll want to send bitstream audio and select Dolby Digital. Then when playing a 4K Blu-ray, check the player app that the audio is set to bitstream. You should then see Dolby Digital in the Sonos app for audio in to the Beam.
