I have an Asus UL20FT-A1 laptop whose sound at maximum is not high enough. I have to open the Sound Settings menu and go over the limitation to get a high enough level. Any idea how I can fix this?

Try the PCM settings in alsamixer - Open terminal (Ctrl+Alt+T) and type alsamixer: enter image description here

You may need to select the sound card with F6 first.

Turning up all the other controls may also help smiley

  • Thanks for the hint! For some reason media keys got broken on 16.10 after upgrade. – anatoly techtonik Oct 22 '16 at 8:57

    On Windows this never happens, volume controls just work. Why does it happen on Linux? – Maxim Egorushkin Aug 27 '17 at 20:46
  • @MaximEgorushkin - AFAIK the PCM setting should by default be at max, just adding or modifying certain software or hardware may change that. Like with Windows and default audio devices :) – Wilf Aug 27 '17 at 23:53

    @Wilf It is not the first time i have to use alsamixer to unmute or increase volumes on Ubuntu and Fedora. It is like it is initialised with random values. IMO, the volume control UI must do that, this step must be absolutely unnecessary. Just venting in general. – Maxim Egorushkin Aug 28 '17 at 0:20

    @Wilf It is like there are two levels of volume settings and the UI tools operate on one level, alsamixer on another. – Maxim Egorushkin Aug 28 '17 at 0:58

1. Open terminal Ctrl + Alt + T

2. Install PavuControl sudo apt install pavucontrol

3. Open PulseAudio Volume Control pavucontrol

4. Output devices Set to 100% (0dB) the port are you using (Speakers / Headphones etc)

You should enable "Louder than 100%" in sound settings.
This works at least in Ubuntu 17.10 Screenshot

    that was the solution for me – pcko1 Dec 28 '20 at 21:32
  • This feature is indeed available, but don't be surprised if you find the sound quality unacceptable: askubuntu.com/a/1316929/1157519 (Bonus: for me the solution was finding and fixing the dialled-down bars in alsamixer.) – Levente Mar 15 at 15:54

This works 100%...

  • right click on volume icon located at top right corner of screen (ubuntu 16 )
  • Select sound settings
  • Go to application section and raise volume up :D enjoy your high sound..

    Definitely not a silver bullet and silly to suggest it might be so. Having said that, this worked for me so thumbs up. – ornous Jan 19 '18 at 21:51
  • That particular context menu item doesn't seem to exist on Ubuntu 18. – isherwood Sep 19 '18 at 19:29

If you were using GNOME 3, definitely you don't need pavucontrol or alsamixer. Instead just use gnome-tweaks to enable over-amplification (in the General tab, or in the Audio tab if any)


If you are using LUBUNTU you might need to try pavucontrol in terminal. In my custom setup ubuntu core + openbox + lxdp I have pavucontrol managing sounds.


I faced volume low issue, I fixed by setting Zoom Application Volume to max.
Settings -> Sound -> Applications see here

Note : I see Zoom volume control available under Applications tab only when Zoom is running.

Ubuntu version I am running : 18.04.4 LTS
My Zoom version : 5.0.413237.0524


This was fixed for me by installing pavucontrol per Sorin Veștemean's answer, going to the Configuration tab and altering my USB headset output format to analog stereo output + mono input, going back to the Output Devices tab and bumping THAT output's volume up to 100% (it was at something like 50%).

Opinion: The fact that Ubuntu fails to retain my audio output settings through reboots and seemingly randomizes the configuration until I go in and manually fix it half the time with a custom-installed tool is a ridiculous usability issue.


This has been an intermittent problem for me. Sound works perfectly fine in windows, but is often low or distored in Ubuntu. Most of the suggested fixes have not worked for me.

I have however found a workaround solution, which is to pair Ubuntu to Alexa via bluetooth "Alexa, Pair" and use her as my in-room speaker. I get full volume without any distortion.


This is what worked for me on Ubuntu 18.04:

From Terminal, I open pavucontrol (no need to install it, it is there by default), and below are the settings I did and which raised the volume on the speakers automatically:
