Feed the matrix into the AVR then go from the AVR to the tv. It will also reduce audio synch problems

Try this first. No reason to have audio from the TV going back to the AVR unless you're using it as a source. Smart TV, netflix.

NEVER use the f^n apps built into the TV... EVER!!! It is just a bad, bad, bad thing to do. And no money excuse since any dedicated streaming device is so cheap (Roku, AppleTV, Fire stick, etc.).

The reason we've brought the audio from the TV back to the AVR via the TV is that there is no additional output or inputs on the matrix so we cant go from matrix output to avr to matrix input (or extender).

There is no reason to go from the AVR to the matrix. Go from the matrix to the AVR then from the AVR to the TV.

Also, if you send audio into the TV then out to an amp, most TVs won’t send Dolby digital out of the tv except for the built in tuner and apps. Also, this is really messing up your lip synch because everything is going to the tv first and it’s trying to process and convert it to PCM before sending it back to the AVR.

Many users "think" their Samsung TV's which don't support Dolby passthrough can accept Dolby surround on its HDMI inputs but it will only be stereo due to the EDID negotiation in which the TV requests stereo . They are confused because the packaging and literature states "Dolby Digital" but that will only come from the TV's internal sources such as its tuner and streaming service and NOT its HDMI inputs. It is amazing how few users who actually own these TV's realize they aren't getting surround sound from their DVD or BluRay player if those HDMi sources go to the TV first and its optical output goes to their sound bar.

Another counterintuitive thing may be at play here: The audio could very well be two channel Dolby Digital. The TV might be telling the HDMI sources to deliver two-channel sound via Dolby Digital. Yes, DD can be just two channels.

And two channel outputs can give you surround via a receiver's ability to derive other channels from two. We used to call that ProLogic, and sometimes it actually is similar to surround sound.
A good answer is easier with a clear question giving the make and model of everything.
