xbox series x interfering with sonos arc

Well, good news is I found the third.  Bad news is that my TV mount sits right over it so can’t get the HDMI cable in straight.  Probably why I initially went with the splitter in the first place.  I’m going to see if I can find a right angle HDMI that might work, otherwise maybe I’ll call SONOS tomorrow.  I think I can isolate it to whenever the TV shuts down, when it starts back up the signal from the splitter must be throwing it off, not sure.

Heh. I’ve got some right angle HDMI adapters I bought off of Amazon in a drawer somewhere, used back in the day. They’re not impossible to find, but as I recall, my corner store didn’t carry them. You may be luckier than I. 

Yea, it’s possible the splitter is interfering in some way with the ARC (or HDMI) signal. Normally, as far as I’m aware, Sonos is always ‘connected’ to it, but it might have issues if the signal keeps disappearing and reappearing….but that’s conjecture. 
 

Yeah, just strange.  The set up worked flawlessly with the Xbox One but now with the series X it seems to be an issue which makes me think it’s not the splitter but probably then Xbox.  It occurs even if the Xbox is off, turning the TV off then on seems to trigger.  Very frustrating to have to unplug an HDMI cable every time I turn on my TV….

I’ll bet. And I’d agree, there has to be some change (perhaps in voltages?) supplied by the two Xbox’s. And I suspect the trouble is being exacerbated by the switch, which is why I’m suggesting plugging everything directly to the TV. You might also want to check with Metra to see if they have a firmware update for that switch… but I’m not holding out a lot of hope. Devices like that often don’t, or are incredibly difficult to update, in my experience. 

Well hopefully Sonos may have some thoughts, I’m sure I’m not the first to have this issue.  I’ll also try one of the 90 degree HDMIs or take a hacksaw to my wall mount 😂.  Thanks for helping troubleshoot 

Not convinced Sonos will have an answer…all they ‘know/see’ is if there’s a signal being generated by the ARC system on the TV. If it’s failing, due to low levels being sent by the XBox to the Metra device, they likely won’t be able to ‘see’ anything in the data other than cessation of the ARC signal.

FWIW, my XBox X is connected to my Samsung directly, and I have no issues. I don’t think I’ve ever connected my old XBox One to this TV, though. But no issues with my Arc at all, works fine, all the time. 
 

Good luck! And good night ;)

Ok, well seems like I just need to find a way to utilize that third HDMI cable

Bruce, so I was able to squeeze into that third HDMI with some modifications and, presto!  All good, thanks so much for your help!

Xbox One had a much more basic HDMI implementation than the Xbox Series consoles (which implemented HDMI 2.1). CEC control was greatly expanded, which is why you can use your TV remote to navigate the Home screen on your Xbox, for example.
