(The quickest way is the Ctrl-Alt-T shortcut)Enter “alsamixer” and press the Enter key.You will now see a user interface like below.

- Select your correct sound card using F6 and select F5 to see recording controls as well
- Move around with left and right arrow keys.
- Increase and decrease volume with up and down arrow keys.
- Mute/Unmute with the “M” key. An “MM” means muted, and “OO” means unmuted.
- Exit from alsamixer with the Esc key.
A caveat here: When you mute or unmute something, pulseaudio might pick it up and mute and unmute other controls, as well as PulseAudio’s main mute.
- Reinstall Alsa and Pulse Audio.
Try to reinstall pulse audio and Alsa, open terminal and enter the following commands:
Purge Alsa and Pulse audio using the command:
sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
sudo alsa force-reload
