Question about audio and video zones

[SY3]

I have 5 rooms where I’m distributing video via an HDMI matrix.  One of the rooms is also an audio zone.  So I wanted to be able to hear the video’s audio source through the speakers in the ceiling. 

Trying to figure out what I need hardware wise to make this work.  Here is my current setup:

Video distribution via HDMI matrix with 6 devices to 5 locations.

I have an 8 zone Control4 Matrix Amp powering the audio only zones.

HDMI Devices:

1. Cable box - Xfinity
2. Apple TV 3
3. Roku box (non-4K)
4. Amazon Fire TV box
5. Luma NVR
6. Sony PS4

Video Locations:

1. Family room with Denon X1300 5.1
2. Kitchen
3. Guest bedroom
4. Game room – is also an audio zone
5. Media room with Pioneer Elite receiver 7.1

I bought a ViewHD HDMI Audio Extractor (https://www.amazon.com/gp/product/B00KBHX072/ref=ox_sc_saved_title_9?smid=A2BUXD0L1W5AKG&psc=1) but didn’t know if I need to buy 1 of each device – 1 for the cable box, 1 for the ATV, 1 for FireTV.  It’s unlikely the PS4 will get used in the game room since it’s in the media room.

Since I only want to use the speakers in the Game room when watching 1 of the inputs, what would happen in the other locations if someone is watching at the same time?

Usually I home run the game room tvs audio output to the 8 zone matrix in that situation. What are all the audio inputs on the 8 zone matrix amp?

At the moment, I have 5 inputs:

2 from main HC800

2 from 2nd HC800

1 from a PC

If I home run the game room’s audio output back to the amp, would that allow me to use the audio zone speakers in the room for any of my video sources?

Yes

Thank you very much.  Last question (for now), would this work to extend the RCA audio:

That should work as well as Audio Control BLD/R/X.
