It might be worth taking a step back and describing your setup.
A couple things are tickling my sixth-sense (but I could be wrong 
)
When a vendor blames an issue on another vendor it’s always worth validating that. In this case, if you can successfully stream Tidal via a PC, phone or tablet it raises a flag.
It sounds to me like you are asking if you can use an optical input to the streamer instead of a wi-fi or wired internet connection. That is an apples-to-oranges situation, but I might be misunderstanding your question.
Maybe you could describe how your streamer is accessing Tidal and any other connections to the streamer.
