Fixing No Sound Issue in Ubuntu 22.04.1 LTS After Upgrading from 20.04 LTS

Ubuntu 13

Upgrading your Ubuntu system is usually a smooth process, but occasionally, you may encounter some issues. One such issue that users often report is the loss of sound after upgrading. In this article, we will discuss how to fix the no sound issue in Ubuntu 22.04.1 LTS after upgrading from 20.04 LTS.

Understanding the Problem

After upgrading from Ubuntu 20.04 LTS to 22.04.1 LTS, you may find that your system’s sound has stopped working. This issue can occur due to various reasons, such as incorrect audio settings, driver issues, or software conflicts.

To understand the problem, you can use the aplay -l command, which displays the list of all sound playback hardware devices available in your system. If no sound output is listed, it indicates a problem with your sound configuration.

Another useful command is lspci, which lists all PCI devices. If this command shows the presence of an audio controller (like Intel Corporation Cannon Point-LP High Definition Audio Controller), but there is still no sound, it suggests a software issue rather than a hardware problem.

Potential Solutions

Solution 1: Check Audio Settings

The first step in troubleshooting is to check your audio settings. Ensure that your sound is not muted and the output volume is set to an audible level. Also, check if the correct output device is selected.

Solution 2: Reinstall PulseAudio and Alsa

PulseAudio is a sound server for POSIX and Win32 systems, while Alsa is a Linux kernel component for controlling sound devices. You can try reinstalling these components using the following commands:

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio

After reinstalling, force reload Alsa:

sudo alsa force-reload

Solution 3: Install pavucontrol

pavucontrol is a volume control tool for PulseAudio. Install it using the following command:

sudo apt-get install pavucontrol

After installation, open pavucontrol and check the settings under the ‘Output Devices’ and ‘Configuration’ tabs.

Solution 4: Update System and Kernel

Keeping your system up-to-date can help resolve many issues. Update your system using the following commands:

sudo apt-get update
sudo apt-get upgrade

If the issue persists, you may need to update your kernel. You can do this using the ukuu tool.
