Thanks for all the input. You guys are the best.
I think the fiber HDMI cable in the attic sounds like the best option for me. The extractor at the sound board also sounds like to way to go.
Thanks again.

The hard part in installing the fiber HDMI will be telling the young man that crawled into the attic that he has to remove the wire he just installed a week ago, and then put in another wire.  ;D

And then tell him you were kidding  ;D, and that he could just use the existing cable as a pull line for the new cable instead..... 8)

Risky business pulling fibre outside of conduit!

perhaps no riskier than having a young person crawl in there ?

Is the fibre HDMI fragile, more so than any other wire? Will there be a problem bending it around corners?

The manufacturer should spec a minimum radius.  The cables are more delicate than an xlr, but not a lot.

IME HDMI cables and network copper cables tend to be a lot more fragile than a fiber cable.

The usual warning with fibre is that bending it below its spec'ed minimum radius even once can cause permanent, it-doesn't-work-any-more-style damage (that very few people can fix), which is why pulling it can be risky. Other than that, fibre tends to be pretty durable, and (depending on the fibre) it can have significantly better tensile strength than copper-based cabling (which is why pulling it through properly-shaped conduit is no big deal).

The weakest links here might actually be the attic type and /or the 2 x 50'  hdmi, which won't offer much pulling power at the coupler...
