[help] I'm too Boomer to stream. :-(


So I purchased a Bluesound node 2i after a previous discussion here. Now I can't get the node or BluOs program to recognize my music on other laptops that are on my same wifi.  When my laptop and hard drive was connected to my Parasound Zdac, I could usb the computer into the dac, and use an optical cable from my tv out to the dac.  The node doesn't seem to have a way to allow my tv into the node's dac (my tv only has optical & hdmi out for sound) & node has no inputs for hdmi or toslink) so I'm stuck with the dac of the node for streaming music and the zdac for tv audio with the two different analog outputs from 2 different dacs going into my integrated amp. I'm frustrated and feel like I spent this money for a ghetto rig, plus I can't even make libraries , etc. Totally confused and have tried making everthing "dicoverable " on network setting to no avail. So lost, angry, sad, confused and frustrated. And I swear to god if millerwhoever says I should have bought a tricked out fuse or dumb little cone, I'm gonna lose my s***.

I am pretty Computer Phobic, and have made some expensive mistakes trying to learn, but at least I have Bluesound running in my house, and added a Bryston BDP3 streamer in my main system, and have a NAS set up.  All of which is a prelude for saying that in our little group posting on this thread so far, that in the Land of The Blind, the One Eyed Man is King.  So,, until someone who knows what the Heck they are doing chimes in, let me try to help and hopefully not send you further down the Rabbit Hole.
   I am pretty confused by the OP.  It seems like you are trying to use
the DAC of the Node 2i but also use the ZDac.  Why?
Sorry, but it sounds like you had higher expectations for the Node.
i have one and I knew Before buying it that you could not use it as an X ternal dac for other gear. And I am a boomer....

Sounds like the OP needs a combo streamer/dac box that accepts outside signals. That does exist but it sure ain’t 500 bucks
This is why it's  a good idea to let people know exactly what you are trying to do and what your setup is. If you would have  mentioned in your post looking for a streamer that you needed hdmi or toslink in to connect a TV no one would have recommended  the Node2i.  It only has ethernet wired or wifi and USB in. Doesn't the Node2i have a return within 30 days policy? 
Further Questions 
1) Are you using the Node2i with WiFi or Ethernet?
2) How is the Node2i connected to your pre amp? (Perhaps you should tell us your whole system at this point).
3) Have you tried using the Internet Radio function of the Node2i?  That should be able to work independently of the Hard Drives that you are trying to access.  If you can’t get that to work then something more basic may be amiss.
4).Where is your dealer in all of this?  Whoever sold you the product should be providing some base level of support?  And have you tried CS from Bluesound?
First, the Node 2i does indeed have Toslink input .. it’s a combo 3.5mm/mini-Toslink port. You’ll need an appropriate cable like this one:

or get an adapter for one end of a standard Toslink cable.

There’s a setting in the BluOS app for allowing/disallowing auto-detect of an Optical-in signal.
