How To Fix HDMI Audio Issues and Video Playback on Ubuntu 22.04

Ubuntu 18

Ubuntu is a versatile and robust operating system that is widely used by many users worldwide. However, like any other OS, it can sometimes encounter issues. One such issue that some users have reported is the HDMI audio and video playback problem on Ubuntu 22.04. This article will guide you through the process of troubleshooting and resolving these issues.

Quick Answer

To fix HDMI audio issues and video playback on Ubuntu 22.04, you can start by checking the HDMI cable and device connections, ensuring they are set up correctly. Then, update your system to the latest version, reinstall PulseAudio and Alsa, and configure the GRUB settings. If these steps don’t work, you can try disabling virtualization support in your UEFI/BIOS settings. Remember to reach out to the Ubuntu community or support team if the problem persists.

Understanding the Issue

The HDMI audio issue typically manifests as no sound output from the HDMI device, even though the system recognizes the device. The video playback issue, on the other hand, could be choppy video, no video at all, or video that doesn’t sync with the audio. These issues can be frustrating, but with a bit of patience and the right steps, they can be resolved.

Preliminary Checks

Before diving into the more technical solutions, it’s worth checking a few basic things:

  • Ensure that your HDMI cable is properly connected and is in good condition.
  • Make sure that your HDMI device (TV, monitor, etc.) is set to the correct input.
  • Check if the issue persists on other operating systems or devices, to rule out a hardware issue.

Solution 1: Update Your System

The first step in resolving these issues is to make sure your system is up-to-date. Ubuntu 22.04, being a new release, is continually being updated to fix bugs and improve performance. You can update your system by opening a terminal and running the following commands:

sudo apt update
sudo apt upgrade

sudo apt update updates the list of available packages and their versions, but it does not install or upgrade any packages. sudo apt upgrade actually installs newer versions of the packages you have.

Solution 2: Install/Reinstall PulseAudio and Alsa

PulseAudio is a sound server for POSIX and Win32 systems, and Alsa is a software framework and part of the Linux kernel that provides an API for sound card drivers. You can install or reinstall these packages using the following commands:

sudo apt install --reinstall alsa-base pulseaudio

Then, to set PulseAudio as the default sound server, use:

sudo alsa force-reload

Solution 3: Configure GRUB

If the above solutions don’t work, you can try editing the GRUB configuration file. This file is responsible for the system boot options. To edit this file, use the following command:

sudo nano /etc/default/grub

Find the line that starts with GRUB_CMDLINE_LINUX_DEFAULT and add intel_iommu=on,igfx_off to the end of the options. This parameter forces the use of the IOMMU and turns off the integrated graphics, which can help resolve HDMI issues.

After editing the file, save and close it (Ctrl+X, then Y, then Enter), and update GRUB with the following command:

sudo update-grub

Then, reboot your system.

Solution 4: Disable Virtualization Support

Some users have reported that disabling virtualization support in their UEFI/BIOS settings resolved their HDMI issues. This solution is more of a workaround and may not be ideal for users who need virtualization support.

Conclusion

The HDMI audio and video playback issues on Ubuntu 22.04 can be frustrating, but they are usually resolvable. The solutions provided in this article should help most users overcome these issues. However, if the problem persists, it might be worth reaching out to the Ubuntu community or the Ubuntu support team for further assistance.
