Sound problems with DAC smsl su-8 and Smart TV

Hey guys, my living room setup is:

Smart TV samsung NU8000 connected by optic cable to DAC S.M.S.L SU-8 which send signal to ADAM AUDIO T7V Monitors

I have a sound problem using different apps(e.g. netflix app, browser or streaming music from phone). Sound stuck on one tone like motorboat and i need to reset audio settings in the TV each time

Youtube and spotify works without any problem

USB connected computer works good as well

any suggestions how can i Fix it?

Thank you!
