Hi all - new poster here looking for help with a strange problem I’ve been having with my Uniti Atom setup that reps have been unable to help me with. I’m definitely a newbee in this area, having gotten into it during the pandemic, so apologies in advance if anything is phrased awkwardly below. My setup right now is:
KEF LS50 Meta speakers
Pro-Ject turntable into the Uniti Atom
AppleTV 4K into an LG G2 tv (OLED65G2PUA)
TV out to the Uniti Atom through the HDMI ARC
When I turn the TV on using the AppleTV remote everything in the system turns on (AppleTV, TV, Uniti Atom). But, without fail, the Atom will go to the HDMI input and, despite the TV being on, will say “No input signal.”
I can force it to work by making it re-handshake, typically by going up to the Atom and either (1) switching it to another input, like Analog 1, then back to HDMI, or (2) unplugging the HDMI cable and plugging it back in. It is seemingly random how many times I need to do this in order to get the signal to start coming through, and sometimes I have to reset the entire Atom to finally get it to work. When it does it finally handshake the Atom works perfectly well sound wise.
This issue has also persisted between TVs and ARCs. At first I thought it was the old Sony TV I was using, so I got the LG. Same issue. Then I thought it could be a bad ARC port or something, so I returned the Uniti Atom and got a new one. Same issue with the new TV and new Atom. So this is definitely something going on with the setup in total.
Final note if it matters but generally for music I have a desktop in another room running Roon that I send to the Uniti Atom through wireless. No idea if relevant but thought I’d add.
Thanks in advance for any help.
