BUT. I have all the chromecasts and the crestron amps running smoothly. google home, I'm able to make as many groups as I want through the 13 zones i have. Spotify plays all our music and we pick what speakers it goes through. The Yamaha amp powers the speakers 5.1 speakers in the family room, and we just have to tune it on or off to stream along with the spotify stream.
Sooooooooooooooooooooooo here's the kicker.
What I'm now looking for is a HdbaseT extender with ARC capabilities. Or I think I am? I want to take the audio channel from the TV and run it to the Yamaha amp to put it to the 5.1 speakers. There was an extender on amazon the other day, but now it's gone. Is this no longer the preferred solution for pulling audio from TV and feeding it to remote amplifier?
So, let me understand what you are trying to do. You have a TV with some local HDMI source that drives it, or you have the TV itself running an app that displays the context you want. You want to take that audio (presumably 5.1?) back to the Yamaha receiver for driving the audio back in the room the TV is in? Do I have that right?
There a few ways of doing this. HDMI ARC, with CEC, would be pretty clean, and provide local control of your sound if the CEC is working properly. What kind of TV is it? You may want to solicit on other forums to see if people have that combination working. A generic HDMI extender should work here. ARC is nothing special, and doesn't push a lot of bits over the HDMI. It's just the equivalent of SDPIF digital audio. This monoprice unit should work: https://www.monoprice.com/product?p_id=15778
and there are tons of these on amazon to pick from. I'd get one that pushes 4K at 18GBPS, even though you are just putting audio over it. The reason is that HDMI can be fussy about negotiating capability, and if you have a 4K, but a 1080p capable ARC device, there is a chance the TV could downgrade to 1080p to it's sources. That probably won't happen, but HDMI is a finicky beat, so if it's a 4K TV, stick with a 4K extender.
If you get one with IR IN/OUT, you could use that as a backup to the volume control not working in your combination using HDMI CEC if you use a harmony or the like at your TV.
The other way to do it is to take a SPDIF connection from your TV and use a TOSLINK balun to send that over the CAT5 connection. But since there is no CEC, you have to get one with IR to send to the receiver to control the volume.
So I think you are better off going with the first approach assuming my understanding of what you are trying to do is correct.
