I've just joined the Naim fold, having picked up a HDMI equipped atom this afternoon. I've not really had the time to crank it up yet (young child settling to sleep) but will do so tomorrow however I've been testing some of the functionality, in particular the HDMI stuff.
Up to now, I've been using a denon receiver from a few years ago (AVR 4311 if it matters) and in preparation for moving to a stereo setup, have set it up as I would the naim, HDMI to the ARC port on the TV and config'd for stereo (well, 2.1 but whose counting?). In this form, as soon as I (or my wife) turned the TV on, the denon would switch on within seconds and set it's input to TV/ARC. This worked well.
I've now moved the cables from the denon to the atom and I don't seem to be getting the same functionality. if the atom was set to it's HDMI input when it was switched off, then it seems to work. well, it takes the atom longer to switch on, and the TV's own speakers seem to work until the atom comes on, something that never happened with the denon. and I've already had it sit there displaying "no input" on HDMI with the TV clearly on once. It broadly seems to work though.
However if the atom was set to a different input when it was switched off, streaming for example, then when I turn the TV on, the atom sits there resolutely off. Are others experiencing the same behaviour? To me that doesn't seem right. the atom should recognise the CEC command and switch on and switch inputs no matter what the input was previously. In fact I'd say that no matter what input it's on, if I switch the TV on, it should switch to the HDMI input.
That's my expectation, and how the denon worked and it made life easy for my wife.
Have I configured something wrongly, am I mis-understanding something? I'd be interested in your thoughts.
I would ask naim directly, but it's a friday night so I've got some time to ask you guys before they get back into the office
