[
this how-to was taken from a post from new user plzd--thanks!]
The procedure I found that has worked for me in different distros:
Code: Select all
wget http://cgit.freedesktop.org/pulseaudio/ ... tils/qpaeq -O /tmp/qpaeq
sudo install /tmp/qpaeq /usr/local/bin/
To be able to use the equalizer, you'll need to install some extra dependencies:
Code: Select all
sudo apt-get install python-dbus python-qt4 python-qt4-dbus pulseaudio-utils
Now restart Pulseaudio. Open a terminal and copy/paste the following commands:
Everything is ready now, but the equalizer needs two modules to be loaded to work, so open a terminal and copy/paste these two commands:
Code: Select all
pactl load-module module-equalizer-sink
pactl load-module module-dbus-protocol
Now iff you get an error and the module(s) can't be loaded, try the following commands, then restart Pulseaudio as explained under step 3:
Code: Select all
rm -rf ~/.config/pulse
rm -rf ~/.pulse
The modules loaded under aren't automatically loaded on system start. So if you want to be able to use the equalizer after a restart without having to run those two commands, you'll have to add those modules either to ~/.pulse/ for your user or /etc/pulse/default.pa for all users. Below, I'm going to add them to /etc/pulse/default.pa and for this, you'll need to open the file as root with a text editor:
Code: Select all
gksu leafpad /etc/pulse/default.pa
And at the bottom of the file, add this to load the integrated pulseaudio equalizer and dbus modules
Code: Select all
load-module module-equalizer-sink
load-module module-dbus-protocol
Save file, and reboot.
Execute by typing
in terminal, or manually make icon launcher (executable qpaeq found in user/local/bin)
