There's the per-stream volume, for the GstPulseSink for use in gnome-volume-control, and there's detecting that we have a "stream" volume, for Totem and Rhythmbox. The former I don't think is very important right now, as long as the latter is implemented. A simple read-only property would be enough to handle that. Does MacOS X present a similar interface for applications to use, or do they implement volume control by themselves like Totem/Rhythmbox currently do with the volume element? If there's something like that in MacOS X, it's a matter of agreeing on the name of the property. -- Fedora-desktop-list mailing list Fedora-desktop-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-desktop-list
