Routing TV optical audio out through the AMP2? I need help fleshing out ideas

Hi all, first time posting here... I have just acquired and set up an AMP2 with my Pi3 and PiMusicbox for Spotify Connect streaming.  I've truly impressed! thanks for building such an excellent little product, and keeping the cost down!

I am trying to accomplish something, however, and I need some advice. In my living room, we have a TV that takes all the HDMI connections from Apple TV, FireTV, PS4 and Cable...  it has a digital audio optical out.  I'm only looking to do a 2 channel system in the room and stop using my crummy TV speakers for audio. I would like to use the AMP2 (because it's awesome!) instead of having to buy a clunky receiver (we are limited on space and $).  The problem with using the amp2 is that I have no way to get the TV Optical Audio into the pi to then play through the AMP2... does anyone know if there is a way to do this - even a round about way?  Some of my ideas, that I don't know will work are:

1. Install a HiFiBerry Digi I/O hat on top of the AMP2 and use that for audio in from the TV (is this a possibility?? - if so this would be the least complicated, least laggy, and least expensive soln)

2. Install the HiFiBerry Digi I/O on a separate pi and have it somehow stream the audio (with minimal delay) to the AMP2 pi?  (is this possible? - if so what software could I use, and how to avoid delay in the signal?)

3.  I don't know... does anyone have any other ideas??

Thanks in advance for any comments or thoughts on this... I'm not sure what to do, and I REALLY don't have anyplace put a huge receiver, nor do I want to spend $400 on one of the little ones that do streaming, when the Pi + HiFiBerry do it so well for <$100.

  Hi,

  you can't combine the Digi+ I/O and the Amp on a single Raspberry Pi. I think the best product for your requirement is this:https://www.hifiberry.com/beocreate

  While it will be more expensive than $100, it can do a lot of additional stuff...

  Best regards,
  Daniel

  I am really interested in an idea like this as well. I think the Beocreate card will be a little too much to achieve what I am trying to do like @someinternguy is trying do as well.

  Here is a diagram of what I have done so far and what I want to achieve next (TV Output) to bypass the incoming audio from AMP2 output. This is a theory and not what may be practical. I have all in place currently besides the "DIGI I/O" in each room. I am thinking if I can bring a output source from each RPi/AMP unit to the RPi/DIGI-I/O unit (with a input splitter of course), I would be able to play audio from the TV Out to the in room specific speakers.

  Ideas?

  That won't work that way because you are trying to feed an analog speaker level signal into a digital line level input of the Digi.

  Ok thanks for the input, but i am still looking for a way to make “something” like this work. If this idea for setup wont work them what will?

  I want to control my squeezebox audio source for all my rooms, but then use my in rolm speakers to play the audio from the TV out. There has to be some clean way to do this.
