I have looked at the audio setup guide and most of it is very generic and does not apply to my setup. I am comparing the audio setups in JRiver 20 with those in JRiver 21 and do not see any differences (20 works 21 does not). This is a server and I don't have any audio device installed, I am using the DLNA device (PSAudio Directstream) exclusively. I believe you when you say there is nothing wrong with version 21, but if I can't find why it is different from 20, then I have to go back to what works. Because of the numerous options in JRiver it makes more sense to me to focus on my particular settings (which work very well in version 20) rather than a very broad how to. I thought that the fact that I could control the volume on the Directstream but not stream music would be some kind of clue that would point me in the right direction, but it doesn't seem to ring any bells with you I guess?
