This is a common problem.

Very few (if any) TV have a AC3/DTS built-in decoder ; so it won't be
able to play those on the TV directly.

When you're doing a connection like:
PC -> TV -> Amp

in my experience, the TV only passthrough stereo PCM ; including over
their digital out connector nothing else. At least that's what my Sony
and Samsung TVs do.

If you want AC3/DTS passthrough, you have to connect your system like:
PC -> Amp -> TV
