No Audio in Lubuntu? - Lubuntu Audio Configuration and Volume Control

6:57 PM

As software continues to require more and more resources, my aging laptop (an HP DV6-7010) has gotten to the point where it requires a lighter distro to perform optimally when bogged down with my gazillion browser tabs and graphics I'm editing. I tried Xubuntu, but found that even it started getting kind of funky when I dealt with a heavy workload. So of course the next step was Lubuntu with its LXDE desktop environment. This was my first experience with anything LXDE based, so yup - I was a newbie just like you probably are. I soon discovered that Lubuntu is the intermediate distro of the Ubuntu family, requiring some under the hood tweaks to get basic functionality like audio going. Don't let this scare you though - these tweaks are quick and easy to apply, and well worth the effort when you need a seriously lightweight desktop environment. The Lubuntu setup actually has taken less time than it takes me to tweak any of the other Ubuntu family distros, simply because I am ONLY adding things and not having to REMOVE things simultaneously that I don't want.

Lubuntu Audio Configuration


It took me about a week to notice I had no audio in Lubuntu by default (I don't use it very much). Fortunately, this is a super easy fix. Open up Terminal and type the following, then press Enter:

sudo apt-get install pavucontrol

Type in your user password, press Enter again, then let the installation finish. Next, type the following in Terminal:

pavucontrol

Press Enter. Now you should see this:

Click the highlighted arrow until you come to the Configuration tab.

Under Built-In Audio, make sure that Analog Stereo Output is selected. Chances are if you have no audio in Lubuntu, it's because this is set to Analog Stereo Duplex or HDMI.

Once you close out of pavucontrol and reboot, you should have fully functioning audio in Lubuntu.

Lubuntu Volume Control Settings


You may notice now that you have fully functioning audio that the Lubuntu volume control is missing from the taskbar (in Linux this is often referred to as a panel, because they're multi-purpose and may not be necessarily used for tasks). Don't worry - this is the easiest fix of all as a simple point-and-click procedure.

Right click anywhere on the panel. Then left click on Add/Remove Panel Items.

Under the Panel Applets tab, click on the Add button.

This should place a volume icon on your panel, and now you can use the Up and Down buttons to change its placement on the panel.

  1. On most of my laptops analog duplex stereo is required. But If you like Lubuntu you might have a look at LXLE. You can find it at www.lxle.net.

    1. Thanks for your comment on that! Yes, chances are if you are already using analog duplex stereo, you won't have this problem, as it does appear to be the default setting for Lubuntu (I haven't been able to test it out on multiple machines to find out). The important part though (to me) is enabling folks to know HOW to change it to whatever they need. Hopefully they will continue changing it if they find one does not work and they don't know if they're using duplex or analog.
