Since only active volumes are rescaled against the reference, it means that closing an App X and then changing the reference volume with the rest of the active Apps will make that App X lose its relative position to the other Apps when it is relaunched. That's the only thing I don't like. I do like the flat logic's intention (use hardware scaling over software scaling when possible) though. It sounds like a smart way to overcome that problem. I believe you mentioned in your earlier email to me that "setting the _stream_, not the sink [which I assume means output]" leaves the reference volume alone. I think this makes sense, so I will give flat volumes another shot when I get home today. So with this explanation, I can understand why Banshee always changes the volume predictably in flat-volume mode. I believe, with the sink set to 100%, I must have set Banshee to something like 92% (while some other app was playing 100% relative to the sink volume). Thus the sink was 100%, and Banshee was 92%. And then I changed the sink volume (thus the reference volume) to near 90%. I closed the other app. This made the sink match Banshee's volume (which by that time was 0.92*0.9 = 83%). So, with my reference volume set to 90% and Banshee set to 92% of that, this means that when playing, Banshee will have a stream factor of 83%, and the sink meter matches this while I play. Whenever I cease playing, the sink will resume displaying the reference volume of 90%. Do I have it correct? And I will add, that this behavior (the sink's visible volume constantly jumping around, even if the reference stays at 90% internally) is what I find a little confusing. However, if, as you say, the Sound Events were treated as any other application in Gnome-Volume-Control (and thus the sink volume matched them when that stream was set to 100%), this would provide nearly identical behavior to Vista, as far as I can tell, since I often adjust all of my apps relative to the Events volume in Vista (which I believe is how I must have achieved what I do in Windows).
