> Can you describe a little more detailed what's happend?

For me, when I try to open mate-volume-control for the first time, if I select either of the ""playback: pulseaudio"" devices, it crashes. Then, if I try to reopen it, it crashes instantly. Oddly, approximately 1 out of 10 times it doesn't crash instantly upon opening, but if I try to interact with it, e.g select a device, it crashes. After issuing this command ""dconf reset /org/mate/volume-control/active-element"" I can reopen it again without crashing instantly, but as before if I select either of those pulseaudio devices then we're back to crash-loop.

Please let me know if I can offer any more useful info,.. I know you are very busy, but I'd like to help :)

I guess it happens on the alsa ones too:

Can you attach a new backtrace, this report is quite old?
Go to /var/tmp/abrt/<folder-of-issue>/
Run 'abrt-action-generate-backtrace' and check the backtrace for lines with
(*). This means no debuginfo package is installed.
Run debuginf-install for all packages marked with (*).
Then run 'abrt-action-generate-backtrace' again.

If you use pavucontrol from the menu or terminal, do you have the same issue?

Sorry I took a while to get this backtrace, haven't been home for a week.

Ok, backtrace is posted. Yes, pavucontrol works. I am still trying to get mate-volume-control to work, though. 

I think this might be a duplicate of this https://bugzilla.redhat.com/show_bug.cgi?id=1045742

I will try recompiling it with these changes, unless you have any other suggestions: http://pkgs.fedoraproject.org/cgit/mate-media.git/commit/?id=874bb5bc2722e3d360704df5fa09802b9835bf88

Regarding comment #1 (on bug 1045742), is there a way to remove pulseaudio from f20 and still have sound? I asked this in the IRC channel and was told it was impossible

Thank you in advance for your reply :)
Comment 17 Wolfgang Ulbrich 2014-05-28 15:05:17 UTC 
Ok, mate-media f19/f20 is also compiles with 'gstmixer applet'.
This cause the issue for switching sound devices with 'sound applet in systray'.
For f21 i switched complete to pulse-audio which fix that, but in result of this change the 'gstmixer applet' is complete gone.
I do not want the same for f19/f20 during a release cycle because i expected that a lot of other users prever using good old gstmixer.
But i've 2 solutions for you.

1. install/using 'pnmixer', with that mixer systray applet you can choose which mixer backend you want to use, choose pavucontrol.
Add it to autostart and disable the the normal applet in autostart.

2. Yes, it is possible to prevent pulseaudio from session start with a dirty trick ;)
Edit this line.
; daemon-binary = /usr/bin/pulseaudio

[root@mother rave]# cat /etc/pulse/client.conf
<snip>
daemon-binary = /usr/bin/pulseaudio-shit
<snip>
The wrong binary path did his work.
And remove pulseaudio-x11 package.
Than the sound comes directly from alsa and the normal mixer systray applet doesn't start, you need to add the gstreamer applet to the panel in this case.
This is what i do........

PS: If you want to rebuild mate-media without gstreamer-mixer use that spec file
https://dl.dropboxusercontent.com/u/49862637/Mate-desktop/Test/mate-media.spec
...maybe use a higher version to prevent updating the package from fedora.

Thank you! So many solutions :)

I choose to recompile it :)
