Dolby Digital works with Netflix, HDMI inputs and OTA Channels. However, Hulu, Dish Anywhere and Disney Plus won't produce surround sound, for content that is marked 5.1 channel.

I recently bought a 5.1 channel Pyle system that supports Dolby Digital and Dolby Digital Plus. I can get full sound from external equipment, local channels and even Netflix. However, no other app - even YouTube will produce 5.1 audio, for the videos that are encoded with Dolby Digital, which work on my desktop hooked up to the tv.

My TV is a Skyworth Android TV 8 based tv.

Maybe those are outputting 5.1 DTS and your audio system doesn't support DTS?

YouTube no longer outputs 5.1 audio anywhere that I can tell. I haven't tried on a computer though. So I wouldn't expect it on a TV. No idea why Disney+ won't output DD+.

Almost nothing from Hulu is in 5.1.
