HDMI Transmitter/Receiver from laptop to tv monitor won't pair after sonos amp system was set up with same laptop. Channel interference?

Sonos amp and connect gen1 set up and work perfectly Set up: amp to 2 passive 3rd party speakers and 3rd party powered sub. hard line out from headphone jack on lenovo laptop to phono in on amp. TV line out HDMI arc to hdmi in on amp. Everything works perfectly. Connect gen 1 system not set up yet so Connect gen 1 is idle at the moment. Ethernet from sonos amp, connect gen 1 and laptop to router. Router is Wireless 7 from spectrum.

HDMI wireless transmitter /receiver was already set up and working with transmitter out on laptop hdmi to remote tv hdmi in (not arc). Doesn’t work Is this a channel problem?….I even tried a new alternate hdmi wireless /transmitter/receiver….same problem...won’t pair...the alternate had 5 channel selection….none worked....would not pair...Any ideas?

From amp to remote tv? I’m probably not understanding what you’re trying to do.

But, if your hdmi transmitter / receiver setup doesn’t work while your Sonos devices are unplugged, then Sonos has nothing to do with your problem.

Gotcha...thanks….my thoughts are maybe router and sonos have a connected channel now that has changed the ability for computer hdmi trans and receiver to pair? Sonos is also wirelessly connected to computer, and can be controlled from the comp

It is highly unlikely you are saturating a wifi channel with a single TV link.

What makes you think that is happening?

What does your wifi monitor show for channel utilization? Under 60% should be usable.

ARC is an output, not an input. There seems to be a lot of confusion here...

I'm too confused to continue, what does a TV monitor have to do with monitoring a wifi channel?
