You should report this as a bug against pulseaudio. It probably means 
that the default settings for your model of card need ammending.

I believe the officially sanctioned way to do this is using gst-mixer 
which still gives access to the raw alsa mixer channels.  This is 
scheduled to be removed in F12 though as the native gnome-mixer has a 
few more features than it had in F11.
