Created attachment 490656 [details] Output of `emerge --info' After emerging xfce-extra/xfce4-pulseaudio-plugin, when clicking the Pulseaudio Panel Plugin and selecting "Audio mixer...", there is this message: Failed to execute child process "pavucontrol" (No such file or directory). Supposedly there should be a dependency in the xfce4-pulseaudio-plugin ebuild.
Until this issue is fixed, emerge pavucontrol manually. When fixed it should be dafe to do `emerge --deselect pavucontrol'.
The plugin can work with any external mixer app (it's configured via the properties dialog). Pavucontrol is just the default. I'll add a postinst message explaining it though.
