I have a Samsung smart TV with optical output connected to an Insignia home theater with an optical to analog converter. It works when watching regular TV but not on YouTube or any of the other apps. I have it set to PCM. What could be the problem ?

I tried that, didn't make any difference. What gets me is that when it's on regular TV it works fine but when I put it on YouTube or any other apps, it doesn't work. That tells me that my converter is working but there's only signal in the optical line when the TV is set to "live TV".
