Feature request: "stream volume modifiers"
Submitted by Tanu Kaskinen

For supporting eg. replay gain and fading, I'd like to see a new concept implemented: "stream volume modifiers". They would be like a second stream volume in addition to the normal stream volume, but the volume modifiers wouldn't be treated as something that is set by the user and thus needs to be remembered. A music player could offload replay gain to pulseaudio by adding a volume modifier for that. Pulseaudio could then even use the hw volume for implementing the replay gain, if that's considered useful.
Stream fading could also be implemented using these volume modifiers, until a better (ie. server-side) solution becomes available.
