first of all I would like to thank you all for the good work and sharing knowledge!
My new Pi Zero W should serve as a music player. From my first research I thought I just molder a Toslink transmitter to the correct pins and configure Raspian... Poor research! (Btw: Why doesn't that work???)
But reading this thread gives me hope for a solution. Is this TinyTOSLINK available for Pi Zero W? The "wired" solution (like in http://abload.de/img/rev_b_pluse7oi5.jpg) suits the purpose, the perfect PCB is not necessary.
BNC would be as good.
Thank you very much and best regards
