I am thinking about a way of feeding an analog amp from the audio out of a TV remotely located, there is currently a SnapAV Binary HDMI balun taking the HDMI signal from a cable box from the rack to the TV. Locally on the TV there is an Apple TV.

I wonder if I use an ARC audio extractor ( available from amazon or any other ) and leave it in the rack between the cable box and the HDMI Extender and extract not only the cable box sound, but also the Apple TV or any sound generated by the smart portal on the TV if the extender is connected on HDMI1 on the TV that is capable of ARC.

I have never used arc over extenders .... please share if you have tried. Thanks!

Don't bother.

I would swap out the HDMI extender set with a version that has audio back channel, typically optical. Then use a DAC to go from optical to analog input on your amp.

That way, no matter what the TV displays, it will output sound to your analog amp. Also, don't forget to set the TV's audio output to PCM 2.0.

You say the cable box is in the rack, likely you've got a coax at the TV unused?

Optic to RCA at TV, feed through coax to a D/A at the rack.

I could return via coax, or via Cat-5 with analog balun... analog balun is giving me humming. The coaxes terminates in the AV panel, not the rack :(

I have used the Snap Hdbase-t extenders with optical return. Converts to analog. Used with cable boxes in the rack and audio to input on Sonos Connect. Or in other cases amps.

but that optical out would be only from the source connected to that specific extender right? what I was trying to do is to extract audio from the ARC coming from the TV.....

All TV sources. It's an optical in at the receiver (TV) end and optical AND analog out at the transmitter (rack) end. Model 600, works very well, not cheap, but cheaper than alternative methods.
