I recently installed ubuntu 18.04 LTS ,and my laptop is dell vostro 14 3468. But since i updated to 18.04 i can't really use pulse audio equaliser. When i start pulse audio in terminal it says

E: [pulseaudio] pid.c: Daemon already running.

E: [pulseaudio] main.c: pa_pid_file_create() failed.

And also my touch pad now sucks, it jumb over frequently, that is annoying.
why is ubuntu 18.04 like this.
please help.

This is how I fixed that on my 18.04 LTS:

I cloned a newer version of pulseaudio-equalizer from github and did the configuration. The way to do that is as follows:

$ cd ~/Desktop && mkdir tmp && cd tmp

$ git clone https://github.com/kernelOfTruth/pulseaudio-equalizer.git

$ cd pulseaudio-equalizer

$ cp -R share/pulseaudio-equalizer/presets/ ~/.config/pulse/

$ cp equalizerrc ~/.config/pulse

$ sudo cp -R share/applications/ share/pulseaudio-equalizer/ /usr/share/

$ sudo cp bin/pulseaudio-equalizer bin/pulseaudio-equalizer-gtk /bin/

$ cd ~/.config/pulse

$ touch ~/.config/pulse/equalizerrc.availablepresets

$ sudo chmod +x /usr/share/pulseaudio-equalizer/pulseaudio-equalizer.py

$ python /usr/share/pulseaudio-equalizer/pulseaudio-equalizer.py

Then at this point just enable the equalizer and apply the settings.

UPDATE: After a while (messing up with audio settings), I discovered that the equalizer never persists (enabling it misbehaved). That took me back to square 1.
To resolve that I downloaded pulseeffects and used it to trick pulseaudio-equalizer like this:

$ wget https://launchpad.net/~yunnxx/+archive/ubuntu/gnome3/+files/pulseeffects_1.313entornosgnulinuxenial-1ubuntu1_amd64.deb

$ sudo dpkg -i pulseeffects_1.313entornosgnulinuxenial-1ubuntu1_amd64.deb

Then I:

1. Launched and enabled equalizer on pulseeffects,


2. Launched and enabled pulseaudio-equalizer


3. Exited pulseeffects

NOTE: Pulseeffects doesn't persist. I have no idea how, but it tricks pulseaudio-equalizer to persist. Beats me.

None of the above solutions worked for me, so here is what I found helpful in my case:

cleanup the previous mess:

sudo apt purge pulseaudio-equalizer

sudo add-apt-repository --remove ppa:nilarimogard/webupd8

Install the pulseeffects (equalizer included):

sudo add-apt-repository ppa:mikhailnov/pulseeffects -y

sudo apt update

sudo apt install pulseeffects

Pulseeffects comes with equalizer so there is no need to install the equalizer separately. The above solution works perfectly in case of Ubuntu 18.04 and I found it here https://github.com/wwmm/pulseeffects/wiki/Package-Repositories

I recently found out that pulseaudio-equalizer is part of the universe repository since Ubuntu 17.04 and the only thing you have to do is to enable the universe repository and you can install the equalizer as sudo apt install pulseaudio-equalizer.

You can install from Webupd8 PPA repo with following commands for Ubuntu 18.04 based distros. Pref file for priority of PPA's package.

First remove main repo's package.

sudo apt purge pulseaudio-equalizer

After install from PPA

sudo add-apt-repository ppa:nilarimogard/webupd8





echo -e 'Package: pulseaudio-equalizernPin: release o=LP-PPA-nilarimogard-webupd8nPin-Priority: 700' | sudo tee /etc/apt/preferences.d/webupd8.pref





sudo apt-get update





sudo apt-get install pulseaudio-equalizer
