[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***.
