Review on 🔌 HDMI 2.0 ARC Extender by AV Access: 4K@60Hz 4:4:4 HDR10 3D Over CAT5e/6/7 Cable, Audio Return Channel, S/PDIF Audio Extraction, HDCP2.2, CEC, PoC & Dual IR, RS232, Atmos & DTS:X by Greg Floyd

On one end: LG CX TV HDMI ARC Patio connected to a "receiver" box (which took me a while to figure out, I thought it should be connected to a transmitter) which connected is connector of Cat5e cable. Other end: Sonos amp connected via HDMI to a "transmitter" connected to a Cat5e connector (the other end of the same cable behind the patio connector). The amp is also connected to my patio ceiling speakers. Cat5e is about 75 feet. The Sonos software picked up the TV ARC connection and we are working as expected. TV sound and TV remote control. A great working product so far. My only cons: - As others have said, I wish there was a cheaper solution that would only provide this audio solution because we don't need video or other audio capabilities. - Devices seem to get very hot. It's like I don't want to pick that thing up because it's hot. I've drafted them with exhaust fans to draw in air and it doesn't matter.
