Hi @Dmusicman73
You have difficulty hearing lyrics so you turn Speech Enhancement off? That seems a bit counter-intuitive. There are three levels of Speech Enhancement - what happens if you use a higher level? Please go to Settings icon » [room with Ultra] » Speech Enhancement » Medium/High and test.
Also, what audio format do you see reported in the Sonos app’s Now Playing screen for the Arc Ultra when you are watching your show?
Please be aware that, as far as the Arc Ultra is concerned, absolutely nothing will change when a TV show plays a clip of a movie - no format change, no change in the number of channels, no change in signal gain. If there is a mis-balance between the sound at two parts of the same show, that is on the in-studio TV sound engineer to resolve.
I hope this helps.
