Hey new member with a Wiim Pro and schitt Gungnir MB. Realized after I purchased the WiiM that the unison input isn't an option. What cable are you using for the input? It sounds like you're possibly using toslink and coax together but maybe I'm misreading that. If you wouldn't mind sending a pic of the cable connections and a recommendation on a cable manufacturer if you're not using the one WiiM provided it would be greatly appreciated!
I'm on the fence about if I made a mistake not purchasing a streamer with the unison USB input. Would love to hear your thoughts on if it matters or not. I know it's schitts recommended input for reasons I don't completely understand
