flat volumes have a serious bug that did not have before

Description of problem:
Some people claim the same problem
flat-volumes have a serious bug , I explained first here https://bugs.kde.org/show_bug.cgi?id=355758 but now I see that same happens in pavucontrol , in KDE, even without kmix running.
Increasing the volume of one stream increases the volume of master channel , doesn't make sense I increasing volume sound in one stream audio and master audio is also increased ? . When I choose volume in one stream , master volume control shouldn't change to the same level of sound of the stream.
Worst is I have a app saved which the stream was saved at maximum, I left application , I reduce master volume to very low level but not mute, I open the app and volume goes to maximum (same level of the stream of the app). Disabling flat-volumes , things back to normal i. e. master volume doesn't change when I change the level of a stream sound .
I don't want disable flat-volumes, I want someone fix flat-volumes in pulseaudio
I increasing volume sound in one stream and master is also increased
When I increasing volume sound in one stream and the master audio doesn't change
As far as I understand, your description matches what flat volumes is designed to do. Sounds like you simply don't like that.
(that said, apps that change volumes on their own *is* a problem, they shouldn't do that... it's not clear to me if that's the case here or not)
When I increasing volume sound in one stream, the master channel shouldn't change and that was the behaviour in early of F21 IIRC
again, what you're describing is precisely what flat-volumes is designed to do, as far as I can tell.
... it scales the device-volume with the volume of the "loudest" application. For example, raising the VoIP call volume will raise the hardware volume and adjust the music-player volume so it stays where it was, without having to lower the volume of the music-player manually.
from the same section, looks like you're hitting a problematic app:
"Note: The default behavior upstream can sometimes be confusing and some applications, unaware of this feature, can set their volume to 100% at startup, potentially blowing your speakers or your ears..."
I don't remember this behavior in F19 , F20 and until the middle of F21,
I thought that flat volumes , should adjust the stream channel and not the master channel .
So I'm not sure about this, but I wonder if the defaults of pulseaudio have changed in these releases, finally if master channel could jump to 100% if a streamer have a bug, I agree that we should disable flat-volumes by default.
