I just installed Xfce 4.6 alpha “Pinkie” and I noticed that when adding mixer plugin to the panel, it didn't refreshed the volume if I tune it from outside. If I open the preferences and then close them, the volume changes correctly.
It works fine if I use mousewheel on the icon too.
*** Bug 4385 has been marked as a duplicate of this bug. ***
I just comitted a bunch of refactorings to the mixer which supposedly also fix this problem. Could you try revision 28052 and see if it's still valid?
I think it's fixed, so I'm going to close the bug. If it still happens, please re-open it later.
This stuff is/was only right when first installing the plugin. After a panel restart, the volume is refreshed normally.
You may want to test in that case for svn.
Yeah, I know. I tested both cases and they are ok now.
