No, I am using MC itself, no other apps or anything. When I launch MC - top left panel shows a row Playing Now under which you can expand: Overview, VSX-921 and Playing from main library. Each of those three have its own icon, VSX-921's one is grayed out always upon a start. That's what i was referring as icons.
Now the library - the view that you get when you click on Audio located on the same top left area. It opens all my library displaying covers etc. Under each CD cover there's a play button which starts particular album to play.
So .. to be precise, this is how it is in my case:
1) start MC
2) VSX-921 play icon is grayed out (no matter whether physical device VSX-921 is powered on or off)
3) trying to play any album starts the playback on PC's speakers, VSX-921 icon remains gray, even though i have configured every mp3 and flac to be sent to VSX-921 over DLNA
4) the only way to start a playback on VSX-921 is to click on VSX-921 (under Playing Now) and doubleclick any song which is in its playlist from previous session, then it suddenly can wake the VSX-921 even from turned off state, icon becomes green and it plays
5) then i can play ANY album and all is directed to VSX-921 as expected
let me know if you have any further questions,
waiting for solution,
thanks
