  GStreamer | gst-plugins-good | Ver: HEAD CVS
           Summary: Enhancement to SunAudio mixer plugin
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: opensolaris
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: brian.cameron at sun.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.23/2.24
   GNOME milestone: Unspecified


The new gnome-volume-control 2.23 program breaks with the SunAudio mixer applet
because the mute state needs to be updated when setting the volume for line-in
and monitor.  These don't really support mute, so the mixer applet just changes
the volume level to 0 to simulate a mute.

This change makes sure that the mute flag gets set for these when the volume is
set to 0, and is unset when the volume is set to a non-zero value.  This way
the mute button is unchecked when you raise the slider above zero when it is
already muted.  Otherwise the volume sticks at 0 and you can't raise the value.
 Clicking the unmute button leaves the value at zero and again mutes it.

Can this patch go upstream?
