How to Fix the No Sound Issue in Ubuntu 20.04 or 24.04
After setting up a new computer with Ubuntu 20.04 or 24.04, I noticed there was no sound coming out (from speakers, headphones or HDMI). there could be several reasons for no sound issue in Ubuntu, Here we have 3 solutions that probably helps to fix No Sound in Ubuntu And Linux Mint.
No Audio on Ubuntu 24.04
The first thing you need to do is check out your headphones and speakers for connection problems. It could be that some audio cable is connected to the wrong port or not connected at all.
Check the ALSA Mixer
Under the hood, PulseAudio uses the ALSA-level volume controls. If you need more fine-grained control over your ALSA-level volume, follow the steps below:
1. Open the terminal.
2. Type alsamixer and press the Enter key. You will see the following output in your terminal.
3. Select your correct sound card by pressing F6.
4. Use the left and right arrow keys to select a volume control. The currently selected item is shown in red.
5. Use the up and down arrow keys to increase and decrease volume levels for each control.
6. When a mixer control is muted, “MM” appears below the volume bar. Note that a bar can be 100% full but still be muted, so do check for this. You can unmute a control by pressing the m key. This changes “MM” to “OO.”
Reload ALSA
Another thing you can try if the sound issue persists is to reload ALSA. To do that, use the following command in the terminal:
sudo alsa force-reloadReinstall ALSA and PulseAudio
If none of the above solutions works for you, try reinstalling ALSA and PulseAudio which must fix the problem for you.
Open your terminal, and enter the following commands:
sudo apt-get remove --purge alsa-basesudo apt-get remove --purge pulseaudiosudo apt-get install alsa-basesudo apt-get install pulseaudiosudo alsa force-reload
Then reboot your system. Check if this helps to Fix No Sound in Ubuntu And Linux Mint.
