@Stirv,
I guess we all may hear things differently and of course there’s the listening environment to consider aswell as the various audio/video sources. There could even be something wrong with your A/V products, or cables etc.
It is difficult to diagnose these things from afar. However I and all my immediate family members have 6 Sonos soundbars between us and that includes 3 Sonos Arcs and we all think that the Arc sounds great.
If you think something isn’t right with your equipment you should really reach out to the manufacturers customer support desk. If you think it’s your Arc that’s at fault, then supply Sonos with diagnostic reports and videos and then go from there.
Personally speaking myself and family members that have Sonos Home Theatres are all happy with them - I’m sorry if you do not believe that’s the truth, but I can assure you it is.
To submit diagnostic reports and video etc. to Sonos, see the below links…
And I do sincerely hope you find the answers you’re looking for with your TV audio in your own listening environment.
P.S. - Yes the Soro App is iOS only (sorry🙏 I perhaps should have clarified that).
