Why doesn't/can't the receiver extract the sound before it goes to the TV?
Either you are setting up incorrectly or you are on to something.
Let's slowing down a bit
Start from source (that includes both audio and video signals) ----HDMI----> AVR.
On the back of the AVR, there should be a few HDMI inputs, take note which input you are plugging into, say HDMI-1.
At this point, audio signal should be and will be detected at the AVR if and only if you are switching to HDMI-1, not HDMI-2 or anything other input.
From the back of AVR, HDMI out will drive the video signal to the TV/monitor.
That's about it.
Now, if you get audio signal back from the TV, it must NOT be in HDMI-1 but could be labeled as TV or something else, but not HDMI-1. It doesn't matter you drive it (the audio signal) back to ARC or optical, it will be on different port, not HDMI-1.
Again, on your AVR, if you switch to, say TV, then you will hear NOTHING from your source.
