You are misunderstanding the flat volume logic. In flat vol the hardware volume is always configured to the *maxmimum* of all stream volumes. And if the streams have different volumes then some of them will be attenuated digitally, *nothing* will be amplified digitally. So, if someone wants playback of exactly one stream a bit louder, then this will have the effect that the output device volume will be increased and digital attenuation happens for all other streams. Which seems to be exactly hat you are asking for, which in turn makes me wonder what your mail is actually about?
