• I am thinking of the useful feature present in the MPUI video player (mplayer for windows) that can enable volume boost to impressive levels (not from the volume slider, but just from the mouse scroll). enter image description here

  • In L/ubuntu I use VLC for the same purpose - normally up to 200%.

enter image description here

  • I have found this and this related questions that imply overall volume boost and do not specify the desktop environment, which usually means they are Gnome-Unity specific. I think the answers related to using the volume properties in order to boost overall volume above 100% is useful in LXDE/Lubuntu too, as Pulseaudio Volume Control can be used in LXDE. enter image description here

But I would like to know if there's a way to do that with mplayer/smplayer - to get more boost.

I thought that maybe mplayer would do in Ubuntu/Lubuntu at least what it can do in Windows. But how?


Open SMPlayer, go to Options > Preferences. Under General, click the tab Audio.

There should be an option Use software volume control and next to it the maximum amplification. See this screenshot (my SMPlayer version is 0.8.3): enter image description here


This is more of a complement to the question but it can stand as a partial answer or workaround.

Pulseaudio Volume Control (not installed by default in Ubuntu, to install go to pavucontrol Install pavucontrol ) would display the audio player/module that is runing and increase that.

So, VLC, already playing at 200%, can get a supplementary boost

And from what I see the sound is not distorted.

Also while playing SMPlayer.

This involves directly the mplayer module.

I guess that this solution can be added to the other answer (that i'll set as the permanent to the question "how to boost audio in smplayer").

  • Ah, I like this, is pavucontrol installed by default on Lubuntu? For Ubuntu it is not... – Gerhard Burger Jan 11 '13 at 14:13
  • @Gerhard Burger: I do not think so but cannot tell for sure. But you can install it can't you? – user47206 Jan 11 '13 at 14:28
  • Yes, I know. I was just wondering why Ubuntu doesn't have it by default, it is way better! – Gerhard Burger Jan 11 '13 at 14:32
  • @Gerhard Burger: better than what app? what is the default in ubuntu unity? there's also xfce4-mixer that deserves maybe a look, but maybe pavucontrol is indeed the best. i thought in fact that it is default in ubuntu proper – user47206 Jan 11 '13 at 14:42

    @GerhardBurger, @cipricus, dpkg --get-selections doesn't show pavucontrol as installed in Lubuntu 12.10. – user25656 Jan 11 '13 at 16:39
