Hello Everyone. I am wondering if anyone can suggest an IPTV app on Apple TV that can output 5.1 surround sound. I am currently using iPlayTV and there is no surround sound from it. Other apps like Amazon Prime, Netflix, etc... are able to output 5.1 sound in my current setup.

Setup: Apple TV(iPlayTV app) --> Samsung(ARC) --> Vizio 5.1 Dolby (eARC).
