Pulseaudio runs your system sound settings. You can bypass Pulseaudio by using ALSA which works behind the scenes.

Install the alsa-utils package by running the following commands:

sudo apt update
sudo apt install alsa-utils

Then, run the following command:

alsamixer

enter image description here

First, use the arrow keys (left and right) to navigate to Auto Mute and use the up or down arrow key to disable Auto Mute.

Then, press F5.

Next, use the Master, Speaker, or PCM volume to change your volume. If I'm not mistaken, I believe you can use the Master volume to attenuate PulseAudio volume in the background. However, sometimes PCM serves this function.

Additionally, if you use a separate sound card or if you use an external device for volume, you can press F6 to select a different sound device.

Please let me know if there are any problems or if this doesn't work.

  • I forgot to mention something. If any volume indicator shows MM at the bottom (to indicate Mute), you can press the M key to mute or unmute. When not on mute, it should show 00 in green. – mchid Jan 05 '22 at 18:52
  • I have changed the Alsamixer settings but nothing changed, the strange thing that I have a dual-boot Windows 10 and Ubuntu, I have tried the OVER-AMPLIFICATION for couple of seconds on Ubuntu and the speakers stuck in this mode, when I open the windows days ago I found the same issue, the speakers are not clear like before, I hope the speakers are not broken down :( @mchid – Mohamed Hesham Jan 05 '22 at 19:27
  • @MohamedHesham I would check to see if there is a setting in BIOS for HD sound or something. Also, check this method to reset your pulseaudio settings. If this works, I'll add it to my answer and close this as a duplicate of the other question. Another option would be to log into guest mode to see if the problem persists there. – mchid Jan 05 '22 at 20:45
  • @MohamedHesham As for the F5 key, it looks like the key is not recognized. Sometimes there is a Fn key or another keyboard setting that switches the function keys between functions (like volume and screen brightness). See if there is a Fn key lock. Also, there may be a key you need to press simultaneously to make the key work as F5. – mchid Jan 05 '22 at 20:49
  • I tried it but nothing changed unfortunately :(, I think my speakers are broke down (( – Mohamed Hesham Jan 06 '22 at 18:49
