I assume this is a side-effect of the flat volumes that recently landed in rawhide. I am playing music in rhythmbox, open the popup in the gvc-applet, adjust the volume, click on desktop background to dismiss the popup. Afer a very short moment, the icon changes to muted, and opening the popup again and changing it does not bring any sound back. Opening the sound capplet shows all output volumes (ie the master slider, the event sound slider and the rhythmbox volume) at 0.
Does this happen with anything but rhythmbox? My guess is a dupe of bug 485547
Also happens with flash
Still happening here.

Same thing happens with audacious, although the audicious volume control isn't moved by either the gnome applet or pavucontrol. Sound still gets muted after sliding the gnome-applet then touching anywhere else on the desktop.
Bastien, commenting out the following lines in gvc-channel-bar.c:on_scale_button_release_event seems to fix this for me. Can you explain those lines ? For me, they seem to have the effect of always injecting a value of zero into adjustment at the end of a drag... value = gtk_adjustment_get_value (bar->priv->zero_adjustment); gtk_adjustment_set_value (bar->priv->adjustment, value);
Probably because I didn't understand what the zero_adjustment was for, and I just copied the code out of on_zero_adjustment_value_changed(). See the patch as reviewed in: http://bugzilla.gnome.org/show_bug.cgi?id=564313 I guess the zero_adjustment was supposed to be to cache the volume before we were muted. I'll try and fix that.
Fixed in gnome-media-2.25.92-3.fc11
