I am new to Naim Uniti Atom and looking for some HDMI insight. I am on the 3.6.0 firmware.
I noticed when the Atom is turned off and I turn my TV on (connected via ARC HDMI) the Atom will turn on, switch to the correct input (HDMI) and the sound will begin playing after a few seconds. I can adjust the volume via the TV remote or my set top box remote (the set top box is connected to the TV via a different HDMI input).
What does not appear to work is when the Atom is already on and set to a different input (e.g. Tidal, Internet Radio, etc). I turn on the TV and the Atom does not change inputs to HDMI. Is this the prescribed outcome? Because I would expect the Atom to auto change inputs to the HDMI input give the ARC connection.
It is set to Auto switching. So perhaps this is a bug given the HDMI input does not engage when the TV is turned on when another input is in use at the same time.
I think this setting means, “auto switch (on/off) when HDMI input is selected”.
There’s also an “on any (selected/active) input” (translated from German) option, which I think will do, what you want.
It’s not default, since people may consider the behavior disrupting, when listening to other sources.
Ok, I feel I was not understanding the toggles under HDMI Auto Switching in the iOS app.
I only see the two choices: “HDMI Auto Switching” and “On HDMI input”.
On: HDMI Auto Switching/On HDMI input
Step 1: TV turned off
Steps 2: currently chrome casting music
Step 3: turn TV on = no change to chrome casting (does not switch to HDMI input)
On: HDMI Auto Switching/On Any Input
Step 1: TV turned off
Steps 2: currently chrome casting music
Step 3: turn TV on = changes to HDMI input (slow reaction, took a few seconds, but it worked)
Thanks for the help.
