What I really > want to say is: "resample to "that" rate if the source if above to it" Philippe, please forgive me, but I'm going to have to give up, for now at least. It's too complicated for me. I don't understand when I tell UPnP that it can do 96000, LMS still doesn't believe it and ignores it. I thought that was the point of setting the player's ability - clearly not.
I can't get C3PO to work with UPnP to get predictability (it works OK elsewhere), and most of my other choices don't work for this or that reason that I don't quite get. I just tried flow, which didn't work at all with the bridge encoding to flac (with rates set to 16/44100), and on I went, mostly getting nowhere. I think that this extra level of complexity is a step too far for me. I applaud all the work you do on this and other bridges, keeping LMS alive, but I am just not quite up to the clever bits.
