Is there another volume control sliding bar for Xfce?

I'm on Xubuntu 13.10 64 bit. I've recently had this issue. As a result the sliding bar that is used to control the volume is gone. I can live without it, I can control the volume from my keyboard but I'd like to know if I can install an alternative to the default sliding bar.

I have Xfce4 version 4.10. My volume indicator looks like this, I don't know what it's called, but it's the default one

On Xubuntu 16.04 the xfce4-mixer plugin is no longer available.

Try

sudo apt install xfce4-pulseaudio-plugin

(which is not in the goodies package)

It looks like you're not using the default Xfce volume slider (perhaps in Xubuntu it is default, but not in Xfce). I suspect that you're using the indicator plugin, which I don't like nor use. I would suggest that you try adding Audio Mixer plugin to the panel.

To have it available you need to:

sudo apt-get install xfce4-mixer
