Unfortunately, the 671 has a known problem correctly switching to the proper input when turned on/when I go into the SmartHub while having ARC enabled. A real P.I.T.A.
I removed the optical and when I play, let's say one of the 3D app documentaries, the sound only comes from the TV's speakers. Am I supposed to connect another HDMI from the TV to the Receiver so the sound comes from external speakers? (Forgive me if, I am an amateur when it comes to AV connections).
For configure the STB, I mean when you set up the TV, make sure you pick the right provider and channel guide.
Unfortunately I'm not running ARC and aren't that familiar with it so I can't help with that. For me, I have the optical out from the TV to my A/V receiver and then when I watch anything internal from the TV, I switch my A/V receiver input to the input that is configured for that optical connection and it works great. I have a Pronto remote and a bunch of macros set up so the switching for me is automatic.
I have turned AnyNet off and so keep your setup the way it is and just turn AnyNet off and see if that helps. AnyNet is a PITA and is really only supposed to work with Samsung devices anyway and since you have a Yamaha receiver I would turn it off. ARC should still work and since with AnyNet off it won't switch the speakers from external to internal it should work. In sum, turn AnyNet off, change speaker setting to external, turn off the TV and A/V receiver (you need to do this in order to get sound) and then turn them back on. Then go to the Smart Hub and try it and see if it works, but remember that the A/V receiver must be on the correct input (at least I would think it would need to be).
