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.
