Got my Up2Stream Pro and SPDIF-out board. The extension board doesn’t fit into plastic case but never mind.
My issue is that there is no sound via Toslink/Coaxial cable. With other words the SPDIF-out board doesn’t pass any sound. And the manual - I love people who write manuals - says that “check function activation instruction on website”. Great, isn’t it?)
Any idea how to activate this thing?
