Brief: No audio in a fresh Ubuntu install? Only see dummy output? No worries. Here are a few methods that you can try to fix the no sound problem in Ubuntu and other Linux distributions.
As it happens with every Ubuntu release, you install or upgrade to a newer Ubuntu version and run in to a number of problems. But then, there is always a way to overcome these big little problems.
One of the most common problems faced is no sound after installing Ubuntu. While there could be several reasons for no sound in Ubuntu, I will share the tricks that worked for me.
Let’s see in steps how I fixed and how you can fix it.
Various methods to fix no audio in Ubuntu
There could be various reasons why there is no sound in Ubuntu. The fix depends on the kind of problem you have.
So, let’s see how can you get the audio back in Ubuntu.
Fixing dummy output in sound settings
First step, just to verify, check if the sound is not muted. Once you verify this, go to Sound Settings:
In the Sound Settings, you’ll find that you have practically nothing here except a dummy output. Quite frustrating. It means that your sound card is not even recognized. Puff!
No worries. The one shot solution which fixed the sound problem for me on my Intel powered Dell Inspiron is to force reload Alsa. To do that, use the following command in terminal (Ctrl+Alt+T):
sudo alsa force-reload
The output will be like this.
You may think that it is hanged or still in processing but it takes only couple of seconds. You can simply close it afterwards by using Ctrl+C.
Now, you need to reboot your computer. Either play some music/video files or check in the system settings to see if it worked for you.
First Alternate method to fix no sound in Ubuntu
If the above problem did not fix it for you, try reinstalling Alsa and Pulse audio in the following manner:
sudo apt-get remove alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
And force reload Alsa again:
sudo alsa force-reload
Restart and enjoy the world of sound, again.
Second alternate method to fix no sound in Ubuntu
Go to your home directory and then go to the hidden config directory. Rename the directory named pulse here:
mv ~/.config/pulse ~/.config/old_pulse
Now reboot your system. The pulse directory should be created afresh and you should have sound.
Third alternate method: Try alsamixer
Open a terminal and use the following command to open alsamixer:
You should see a screen like this:
Check if the speakers or your desired audio output is muted here. MM means mute and OO means unmute. If your desired audio output (mostly it’s speakers) or the Master is muted, unmute it.
You can exit the screen using Esc key.
Fourth alternate method to fix no audio in Ubuntu
Open the terminal and edit speech-dispatcher file by using the following command:
sudo gedit /etc/default/speech-dispatcher
In here, change
Reboot and enjoy the sound.
If it fixed your sound problem, you may want to fix brightness issue as well. Fixing the sound problem is definitely one of the must to do things after installing Ubuntu.
