I right-click on the volume control plugin in the xfce4-panel, and as soon as I click "Properties", the volume control slider on the panel is set to zero, though the sound does not really get muted. I can't change the volume using this plugin until I restart the panel. When I start it from the console, I get the same message lots lots of time: ** (xfce4-panel:896): CRITICAL **: file vc_oss.c: line 210 (vc_get_volume): assertion `mixer_handle != -1' failed
Additional information: I'm using cvs version of Xfce4.
that means it cannot open the mixer device. When you do not enter properties, it works normally ?
Reducing the severity to minor, because it sounds like a configuration issue to me. Reporter, please try to provide us with a little more information.
resolving to invalid, please give more info and reopen
