[Bug 1376776] Re: Sound panel's "input" selection resets the default on every invocation

 

Thanks, I'm trying to analyze it.

One clue could be, that if this started happening recently, it could be
related to the fix for https://bugs.launchpad.net/ubuntu/+source/unity-
control-center/+bug/1367693 - in which case one could try moving back to
the previous version to see if it's fixed.

(Although I rather suspect that fixing that bug caused another bug to
surface, rather than that the fix was wrong...)

Another interesting thing to notice is the difference between
on_output_selection_changed and on_input_selection_changed in gvc-mixer-
dialog.c, as the output selection has this line:

        g_debug ("\n\n on_output_selection_changed - active %i \n\n", active); 
        if (active){
                return;
        }

...and input has not. I could try adding that line to the input path
too, to see if that resolves the problem...

Title:
  Sound panel's "input" selection resets the default on every invocation

Status in “unity-control-center” package in Ubuntu:
  Confirmed

Bug description:
  Every time I open gnome-control-center, it resets my default audio
  source in pulseaudio.

  $ pacmd info | grep Default.source
  Default source name: alsa_input.usb-046d_081b_4D515DC0-02-U0x46d0x81b.analog-mono
  $ gnome-control-center sound&
  [1] 30266
  $ pacmd info | grep Default.source
  Default source name: alsa_input.pci-0000_00_1b.0.analog-stereo
  $

  The bugginess should be self-evident.  Opening the control app should
  not change the configuration.
