I just added a Chromecast device to my AVR-3311CI, and tried to use HDMI4 and had some trouble.
It's been a while since I've done input assignments. I *vaguely* recall that there's some way to hide unused inputs, and I must have done so in the past. I can't for the life of me figure out how to un-hide them now...
I realize that on input assign there are really just "slots", and you supply a name for each and select an input from a drop-down (in web interface, but similar concept using remote - I tried both!)
Thing is, there are 6 HDMI inputs (PLUS other types of inputs), but not enough slots to use them all. There is a gap in my list.
I was able to set-up the Cast device on HDMI 4 by re-assigning the last slot, which was assigned to V.AUX, which I seldom use.
So, I got it to work, but it's bugging me that I have two HDMI inputs that I apparently can't use.
Here is my current input assign:
Bluray HDMI1 None None
AppleTV HDMI2 None None
TV None OPT1 None
Cable HDMI3 None None
(gap on web page)
CAST HDMI4 None None
These are all of the slots that are available, and can see no way to add more.
I wrote down all of the settings and reset the input assign, but that didn't buy me any more slots.
How do I get my "hidden" slots back?!
BTW, if you are wondering why I have both Apple TV and ChromeCast, I'm a software developer, and am working on an open-source text-to-speech service/audio file player (based on node google-home-notifier, but will be renaming my fork google-cast-public-address, since it now does more than just TTS and as well isn't limited to just playing on Google Home..., and needed a Cast device to test casting to devices other than Google Home... It's main use is to send asynchronous TTS feedback to a Google Home device from home automation controllers, etc.
