I use my Sonos Ray perhaps in an unconventional manner.
I do not connect to it via optical cable - but via airplay using an Apple TV.
So when I stream video from an ATV all audio is via airplay to the Ray.
BBC iPlayer and Netflix sound fine with dialogue - but Disney Plus is terrible - and the speech enhancements are ineffective using the Sono Ray options and EQ.
I have only owned my Ray for a couple of days - it sounds great apart from Disney Plus speech which is dismal to say the least!
