10

I searched for similar questions but didn't find a solution for my problem. I have a Samsung laptop (NP300) that worked perfectly with windows 10. Recently I installed Ubuntu 16.04 and I'm trying to get used to it, but since I have Ubuntu there is no sound from the computer. Not from music, neither movies nor youtube. I tried system settings/sound, the check doesn't do anything. I tried the 'alasmixer' but still didn't change anything. Can someone help?

-Open a terminal and type alsamixer

-Check that all sounds are correctly set and you are setting it for the correct audio device.

-Go to sound settings and press the test button. Though it might not work for you but it strangely worked for me.

I had the same problem.

Use pavucontrol and the check all the settings. In particular go to the Configuration tab and change the values from the drop list.

The correct selected item should be Analog Stereo Duplex.

Run commands below:

sudo apt-get remove --purge alsa-base
sudo apt-get remove --purge pulseaudio
sudo apt-get install alsa-base
sudo apt-get install pulseaudio
sudo alsa force-reload

then reboot your system.

For 'dummy output' issue.

Before performing mixer reinstall or upgrade, check your audio output status in BIOS.

Since the sound is working in Windows, it may be a driver issue. Check whether the hardware is detected properly (All Settings -> Sound -> Output). Furthermore, you could try whether sound is working with Ubuntu 14.04 or 17.04 with a live stick.

If this does not help, it would be best to use the official sound troubleshooting advices from ubuntu: https://help.ubuntu.com/community/SoundTroubleshootingProcedure (especially I'd suggest to try to restart pulseaudio).
