spdif to lumin u1 mini

I'm trying to find a way to get the optical (spdif/toslink) out from my tv to stream to my lumin u1 mini. This seems to be much more difficult that it sounds. Any suggestions?
The Lumin U1 is a streamer and not a Dac it also doesn't have digital inputs just outputs. What Dac are you using and why don't you run the TV straight into your Dac?
Because my dac doesn’t have an spdif input but it does accept streaming from the lumin
So your Dac has a USB input? Does it have any other inputs or more than one USB.
