[PROBLEM] HDMI from TV

[trollox]

Hi Moode people.

I'm wondering if it's possible to take the audio from the TV via the digital optical output to the HDMI input on the Pi?

There is no "HDMI input on the Pi".

Isn't this an HDMI socket? 
I'm pretty sure this is what my Pi looks like. 
There's a HiFiBerry DAC+Pro sitting on top of it.
My original question was regarding the possibility of using Moode to take the audio from the telly via the digital audio output socket, connected to an HDMI cable and play the said TV audio through my speakers. The ones connected to my HifiBerry +Pro, which is connected to a Raspberry Pi. via said HDMI socket. 
Excuse my English.
