Is there a audio equalizer that actually works?

Postby reconditedave » Sun Jan 29, 2017 6:44 pm

I have a bluetooth speaker, which normally works great, but by default it sounds terrible using Linux Mint.

There are a bunch of sites, like this one: http://askubuntu.com/questions/72679/is-there-any-sound-enhancers-equalizer that detail how to install the pulseaudio equalizer.

This is the one I used:

Code: Select all

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install pulseaudio-equalizer

I can then select an audio profile that enhances the bass and treble and viola, I am getting great sound out of the speaker.

That is, until I reboot and Linux Mint no longer sees *any* sound devices. Before pulseaudio-equalizer was installed I had HDMI and S/PDIF (by default), then using the Bluetooth tool, I added my speaker.

After, I when I open my sound settings I see this:

There appears to be no way to add in the sound devices afterwards, and removing pulseaudio-equalizer did not go well.

So I had to reinstall Linux Mint - which I probably had to do anyway since I have been upgrading for the past few versions, so a clean install sounded like a good idea. Just for giggles, I decided to do the same pulseaudio-equalizer install on a *clean* 18.1 installation.

I got exactly the same problem.

After install #2, the question is now, what audio equalizer can I install that will not destroy sound capabilities under Linux Mint?

After installing PulseAudio Equalizer open System Settings> Multimedia> and click on Audio and Video to the left. When the options open click on "LADSPA Plugin Multiband EQ on Built-in Audio Analog Stereo" and click the Prefer button at the bottom. Do this for all sections for Audio that you wish to use the equalizer and PulseAudio Equalizer will automatically load when you start programs using audio that you have set it as the "preferred audio plugin". If you don't it will fall back to the default audio settings but you can load PulseAudio Equalizer at anytime you chose to by starting it from Multimedia in Menu/Launcher. I have been using it for years now and understand that it can be somewhat confusing at first.

This is a Linux Mint Forum. There is no System Settings > Multimedia

BTW: Anyone else having problems with pulseaudio, and finding there is NO sound after a you restart, there is a simple fix. Run this command:

Code: Select all

rm -rf ~/.config/pulse


reboot, and you are good to go.

If you ever open the pulseaudio mixer, you will have to blow away the pulse directory again.

FWIW, the installation worked fine for me. Just as the OP, I did:

Code: Select all

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install pulseaudio-equalizer


Mint 18.1 XFCE 64 bit

Also installed and worked on laptop running 17.? XFCE 64 bit

There's also

Code: Select all

libasound2-plugin-equal

"equalizer plugin for ALSA"

Set it with alsamixer(gui) or, far better, qasmixer.
Mint 18.2 Xfce/fluxbox/pulse-less - Xubuntu 16.10/fluxbox/pulse-less
Please edit your original post title to include [SOLVED] if/when it is solved!

Perhaps the bluetooth element is adding a wrinkle I'm not familiar with but I know there is one aspect many people, myself included, overlook at first. The box for "Keep settings" needs to be check for your current settings to survive a reboot.

As for removing it, if you just remove "pulseaudio-equalizer" you are only removing the GUI tool. What the GUI controls is one part of the Swh-plugins so if you uninstall the GUI tool and don't remove the "Keep settings" checkbox you will need to remove the plugins also.

Flemur, I have tried that approach on 17, 17.2 and LMDE2 and it has never worked. I have seen the EQ in qasmixer only once before but adjusting it did nothing and the other times it just wasn't there. Is there something I might have missed or is it possible that some hardware just doesn't get along with it? I know I never spent more than 5 minutes trying to get it to work since I've known about the Swh-plugins version since my first ever Linux install so I'm thinking it may be me.

I'm not so sure EQ is the problem or solution. Can you try going to Sound Settings and enabling A2DP?

Same problem here. It shows up in qasmixer but doesn't work(doesn't change the sound at all).

This is in Linux Mint 18.1 KDE. From menu I select Settings > System Settings> Multimedia >Audio and Sound. I installed PulseAudio Equalizer in 18 and have just installed the point update to 18.1 without making any other changes to the system settings. I have the equalizer in my list of Start at Start Up and sometimes forget that it is even loaded. It just works that well for me.

I successfully installed pulseeffects on Ubuntu 17.10 from the source today (2017-10-27). Repository: https://github.com/wwmm/pulseeffects Installation from source: https://github.com/wwmm/pulseeffects/wi ... rom-Source

The utility works ok. Modifying some parameters can cause it to crash. For what I've been able to see at moment, pulse-audio always resumes working normally upon pulseeffect exit.

I particularly like pulseeffect equalizer including input and output volume control. The frequencies of the equalizer can be arbitrarily set. The effect range of each frequency bar can be set as well using the "Quality factor": A higher quality factor means an effect on a narrower range of frequencies, while a lower quality factor means an effect on a wider range of frequencies.

Overall, I warmly recommend pulseeffects.

I hope that it will be made available as a service in the future. I'd also like to be able to use it as a desktop applet.

I've been reading about this on ubuntu and mint and other Linux support sites for years. I've come to the conclusion that there isn't a reliable system wide EQ available unfortunately.

The fact that it always seems to require a ppa to install it is a clue that it's unreliable.

Fortunately for me, I go in the opposite direction and almost never use EQ.
