OSMC Equalizer Setup

A Kodi addon simplifying the installation of pulseaudio equalizer on OSMC systems.

Tested on raspberry pi 3b.

It installs pulseaudio together with the required modules and the Linux Addon Repository. It further configures the system to run with pulseaudio.

Version 1.0.1

Installation

  • Download latest zip from releases.
  • In OSMC, select install from zip and install this addon.
  • Now it is possible to select different scripts in the OSMC Equalizer Setup settings.

Install from zip

settings -> Add-on browser -> Install from zip file

Prepare System

settings -> Add-on brower -> My add-ons -> Program add-ons -> Equalizer Setup -> Configure

Install -> Prepare System with Pulseaudio

Reboot

Reboot is important to start OSMC with pulseaudio.

Enable the Linux Addon Repository

settings -> Add-on browser -> My add-ons -> Add-on repository -> Linux Addon Repository -> enable

Install Pulseaudio Interface

settings -> Add-on browser -> Install from repository -> Linux Addon Repository -> Program add-ons -> Pulse Equalizer

Direct audio though pulseaudio

settings -> System -> Audio -> Audio output device -> Pulseaudio Sound Server

Bluetooth devices with Equalizer

Pulseaudio is in conflict with ALSA if it comes to bluetooth devices. Therefore alsa-bluetooth needs to be disabled, when bluetooth shall be used with pulseaudio equalizer.

settings -> Add-on browser -> My add-ons -> Program add-ons -> Equalizer Setup -> Configure

Install -> Disable Alsa Bluetooth

Revert everything

Remove Pulseaudio from the System

settings -> Add-on brower -> My add-ons -> Program add-ons -> Equalizer Setup -> Configure

Remove -> Remove Pulseaudio from System

Enable ALSA Bluetooth

settings -> Add-on brower -> My add-ons -> Program add-ons -> Equalizer Setup -> Configure

Remove -> Enable Alsa Bluetooth

Behind the Scenes

There are five shell scripts that also could be launched from command line. They are located in

./kodi/addons/script.equalizersetup.osmc/resources/lib/

install_equalizer: Install pulseaudio, pulseaudio-equalizer, swh-plugins,pulseaudio-module-bluetooth, alters the OSMC startup script, downloads and installs the Linux Addon Repository

remove_equalizer: removes pulseaudio, pulseaudio-equalizer, swh-plugins,pulseaudio-module-bluetooth from the system, recovers original OSMC startup script

disable_alsa_blue: stops and disables bluealsa.service

enable_alsa_blue: enables and starts bluealsa.service

restore_pa_setting: restores the pulseaudio settings to default

Those script are launched with sudo -u osmc, obviously they need root access to make the changes to the system. Currently there is no password request by osmc for sudo, this might change in the future. In this case this addon needs to be altered.
