Why doesn't ARC matter with this?
In the article above, the author states that ARC probably won't matter in situations where this wireless HDMI kit will be used, but ethernet might. Can you please explain why not? I recently completed a job where my customer had a 75" Samsung F8000 mounted 25' away from his component closet. Since his prior TV was an oldie that was connected with ancient cables, I needed a way to run HDMI to the TV. However, there was no way to do this since there was no attic or crawlspace access, his room was open-concept with no way to conceal wire on the outside of the walls, and his walls could certainly not be opened up (they were covered in $100k worth of Italian marble plaster. The only option was to use a wireless HDMI kit. The customer was disappointed to find that there was no way to get surround sound from his TV's smart TV features because the kit that we used (and every other wireless HDMI kit) didn't support ARC. Of course, he could use his blu-ray player or other devices to provide smart functionality to his setup, but he didn't like having to use another device to watch Netflix when his $7000 TV had it built-in, not to mention the fact that the Samsung's smart TV features far exceeded any blu-ray player's.
Any advice for how I could have remedied this problem without ARC over wireless HDMI?
