Experiencing no sound on Ubuntu 24.04.2 LTS after installation or an upgrade? Common issues include no audio from speakers, headphones, or HDMI, “dummy output” in sound settings, or crackling/static sounds. A few users report, Ubuntu 22.04 does not detect sound devices. Well, No Sound Issues on Ubuntu can occur from muted settings, misconfigured audio servers (PipeWire or PulseAudio), outdated drivers, or unsupported hardware. Whatever the reason, here are five effective solutions to fix the Ubuntu 24.04 no sound problem, restore audio, and enjoy music, videos, or calls on your Ubuntu system.

How To Fix No Audio Issues On Ubuntu Linux
Ubuntu 24.04.2 LTS enhances audio with PipeWire for low-latency, modern hardware support via Linux kernel 6.11, and flexible output switching in GNOME 46. These features make it ideal for multimedia and development, but misconfigurations can cause sound issues. However, if you cannot hear any sound on Ubuntu, or if no sound output devices are listed after upgrading from 21.10 to 22.04, try the following solutions.
Before You Start: Check Basic Settings
If you’re experiencing no sound in Ubuntu, check the basic troubleshooting steps first. Ensure your speakers are connected, turned on, and the volume is adjusted. Additionally, confirm that sound isn’t muted in system settings or in the application playing the sound.
- Ensure the sound isn’t muted in system settings or in the application you’re using to play audio.
- Verify your speakers are connected properly, turned on, and the volume is adjusted.
- If you have multiple sound output devices, ensure the correct one is selected in the system settings.
- Some laptops have mute keys or switches (e.g., Fn + mute). Try pressing that key to see if it unmutes the sound.
- Check for loose connections or try a different port (e.g., front vs. rear audio jack).
Check and Adjust ALSA Mixer
The Advanced Linux Sound Architecture (ALSA) controls low-level audio. Misconfigured ALSA settings can cause no sound or “dummy output” issues.
- Open the terminal by pressing Ctrl + Alt + T.
- Type alsamixer and press the Enter key to Launch ALSA Mixer
- Select your correct sound card by pressing F6.
- Use left/right arrow keys to select controls (e.g., Master, PCM, Headphone). Use up/down arrows to increase/decrease volume. Ensure levels are above 0.
Note: The currently selected item is shown in red.
- If “MM” appears below a volume bar (muted), press m to unmute, changing it to “OO.”
- Press Esc to save and exit alsamixer
Now play a sound (e.g., via aplay /usr/share/sounds/alsa/Front_Center.wav) to check if audio is restored. If ALSA Mixer shows no controls or “dummy output,” proceed to the next solution.
Reload ALSA Drivers
Reloading ALSA drivers can fix issues caused by kernel or driver conflicts, common after Ubuntu 24.04 upgrades.
Open the terminal using Ctrl+Alt+T
Now, run the following command in the terminal:
alsaloop sudo alsa force-reload
This unloads and reloads ALSA modules, refreshing the audio stack. Once it’s done, reboot your computer, and test your sound again to see if it is working.
If reloading fails, check your kernel version (uname -r). Ubuntu 24.04.2 uses Linux kernel 6.11, which supports newer audio hardware. Update with sudo apt install linux-generic-hwe-24.04 if needed.
Troubleshoot PipeWire (Ubuntu 24.04 Default)
Ubuntu 24.04 uses PipeWire as the default audio server, replacing PulseAudio in most cases. Misconfigurations or conflicts with PulseAudio can cause no sound, crackling, or “dummy output.”
Open a terminal and run: systemctl –user status pipewire
Ensure it’s “active (running).” If not, start it using the command: systemctl –user start pipewire
Also, confirm PipeWire’s PulseAudio compatibility layer is active using: systemctl –user status pipewire-pulse
Well, if it’s inactive, start it using systemctl –user start pipewire-pulse
Also, check Audio Devices, using pactl list sinks. If only “dummy output” appears, your sound card isn’t detected.
Try Reset PipeWire Config using the following command:
rm -r ~/.config/pipewire ~/.cache/pipewire
systemctl –user restart pipewire pipewire-pulse
Once done, restart your computer and play a audio sound to check if the No Sound Issues on Ubuntu fixed.
Note: Conflicts between PipeWire and PulseAudio can cause issues. If PulseAudio is installed, consider removing it.
Reinstall ALSA and PipeWire
Again, reinstalling ALSA and PipeWire can resolve corrupted configurations or missing dependencies.
Open your terminal Ctrl + Alt + T, and enter the following commands:
Remove ALSA and PipeWire and Purge existing packages: sudo apt remove –purge alsa-base pipewire pipewire-pulse
Reinstall ALSA and PipeWire: sudo apt install alsa-base pipewire pipewire-pulse
Now, Reload ALSA using the command: sudo alsa force-reload, and to restart PipeWire services, run the command systemctl –user restart pipewire pipewire-pulse
Finally, restart your system with sudo reboot and check whether sound is restored.
Install pavucontrol (sudo apt install pavucontrol) for a GUI to manage audio devices and confirm output selection.
Switch to PulseAudio (Alternative)
If PipeWire fixes don’t work, try switching to PulseAudio, Ubuntu’s older audio server, which may be more compatible with certain hardware.
Open your terminal Ctrl + Alt + T, and run sudo apt install pulseaudio to install PulseAudio.
Next, you need to stop PipeWire services by running the following commands:
systemctl –user stop pipewire pipewire-pulse
systemctl –user disable pipewire pipewire-pulse
Now you need to enable and Start PulseAudio by running the command: systemctl –user start pulseaudio and systemctl –user enable pulseaudio.
And finally, verify PulseAudio using the command systemctl –user status pulseaudio
Restart the computer using sudo reboot to apply changes.
Switching to PulseAudio may resolve issues with apps like Audacity that struggle with PipeWire. Avoid running both servers simultaneously to prevent conflicts.
FAQs About Ubuntu 24.04 No Sound Fix
How do I fix Ubuntu 24.04 no sound issues?
Check volume settings, adjust ALSA Mixer, reload ALSA drivers, troubleshoot PipeWire, or reinstall audio components.
Why does Ubuntu 24.04 show “dummy output”?
“Dummy output” means the sound card isn’t detected. Reload ALSA, update the kernel, or reset PipeWire configs.
How do I troubleshoot Ubuntu 24.04 sound issues with PipeWire?
Verify PipeWire status (systemctl –user status pipewire), reset configs, or switch to PulseAudio if issues persist.
What causes crackling sounds in Ubuntu 24.04?
Crackling may stem from PipeWire buffer issues or hardware conflicts. Adjust settings or use PulseAudio.
Can I use PulseAudio instead of PipeWire on Ubuntu 24.04?
Yes, install PulseAudio, disable PipeWire, and enable PulseAudio for compatibility with older apps or hardware.
