Note that if alsamixer command returns error, it’s probably because you have more than one sound card. If your desired audio output (mostly it’s speakers) or the Master is muted, unmute it. Open a terminal and use the following command to open alsamixer: alsamixerĬheck if the speakers or your desired audio output is muted here. The pulse directory should be created afresh and you should have sound. Rename the directory named pulse here: mv ~/.config/pulse ~/.config/old_pulse
Go to your home directory and then go to the hidden config directory. Try starting Pulseaudio and see if it works: pulseaudio -start Third alternate method: remove old Pulseaudio config Second alternate method to fix no sound in Ubuntu Restart and check if sound is back or not. If the above problem did not fix it for you, try reinstalling Alsa and Pulse audio in the following manner: sudo apt-get install -reinstall alsa-base pulseaudioĪnd force reload Alsa again: sudo alsa force-reload First Alternate method to fix no sound in Ubuntu Either play some music/video files or check in the system settings to see if it worked for you. You can simply close it afterwards by using Ctrl+C. You may think that it is hanged or still in processing but it takes only couple of seconds. To do that, use the following command in terminal (Ctrl+Alt+T): sudo alsa force-reload The one shot solution which fixed the sound problem for me on my Intel powered Dell Inspiron is to force reload Alsa. It means that your sound card is not even recognized. In the Sound Settings, you’ll find that you have practically nothing here except a dummy output. Once you verify this, go to Sound Settings: Fixing dummy output in sound settingsįirst step, just to verify, check if the sound is not muted. This information maybe useful in some stages of your audio troubleshooting. It tells that it is Intel Sunrise Point-LP HD Audio and it has the Linux driver snd_hda_intel and the sound is served with Alsa. Look closely in the audio section of the above output. Type: Laptop System: Dell product: v: N/Aĭevice-1: Intel Sunrise Point-LP HD Audio driver: snd_hda_intel You should see some information like this: :~$ inxi -SMA Now check the system, machine and audio information with this command: inxi -SMA
