2 ways of doing it,

 

1. everything plugged into the TV, you use the tv remote to change the input to your different sources, ARC sends the sound to the AMP, the AMP stays on the tv setting to provide sound, tv remote controls volume of the amp. amp should turn on with the TV.

 

2. everything is plugged into the amp, you select different modes on the amp to select the different sources, the amp controls the sound.

 

personally i find #1 easier as there is no mucking round with the amp and the TV controls everything bar your different inputs

 

Just bear in mind you will either get basic compressed DD 5.1 up to 1Mbps (if your TV is sensible) or basic 2.0 (if it's not). No uncompressed PCM (big headache if you want to use Kodi for live TV), no 7.1, no fancy formats like DTS:X or Atmos.

Apparently there is a new version of ARC called eARC which resolves those technical limitations, but both your TV and receiver will need to support HDMI 2.1.

Using the TV as your HDMI switch also means you can't use a lot of your receiver's fancy features, or see its OSD - it will act as an amplifier only. I have a different audio delay set in my receiver for each of my inputs - original Chromecast requires over 250ms for proper lip sync.

I think ARC's primary use case is for things like sound bars, which don't have HDMI switch capability and can't make use of advanced audio formats anyway. It is a little bit wasted on a full-featured receiver. But I do understand the convenience of having everything plugged into the TV.
