Connect 2 LG CX TV's to Sonos AMP HDMI-ARC via Switch

I am looking for help. Would it be possible to connect two TV’s to a single Sonos AMP by using a Switch? If so, is anyone aware of an auto switching Switch that could do this?


For context, I have an LG CX 48” for PC and above it I have an LG CX 65” for movies. I only use one of them at the time. I would love to find a solution where I could connect them both through the HDMI ARC port and not have to introduce extra steps when switching screens.


Thanks for looking.

Hi @Ferenc 

Welcome to the Sonos Community!

I’m not aware of any such HDMI splitters - though they may well exist.

As your PC likely has a 3.5mm Line Out connection, I would instead recommend connecting the larger TV to your Amp with HDMI and connect your PC to the Line-In on the Amp with an appropriate cable.

As long as the larger TV is on, the Amp will ignore the Line-In input and instead play the HDMI-ARC signal. Turn the big TV off, and you will be able to hear your PC through the Amp.

I hope this helps.

Edit: You will of course only ever get stereo sound from your PC.
