provide a starting point for writing clients and server modules.explain their underlying design and important implementation details.This document tries to fill the gap and provide an overview of the PulseAudio features, architecture, and internals. The learning curve for the module writer is high too. Advanced configuration looks mysterious because one need to understand what happens under the hood first. In result, the overall picture remains unclear. Unfortunately, the available documentation doesn’t give a bird-eye view and an explanation of PulseAudio features and design and doesn’t cover many implementation details. D-Bus API and C API are also documented well. Modules page contains a complete list of existing modules with parameters. PulseAudio has Documentation page covering many specific problems that may be encountered by user and developer. This led me to dig into PulseAudio internals and eventually to this document. Many Linux distros employ PulseAudio, and their users will be able to improve network service quality without changing the workflow. We decided to implement a set of PulseAudio modules that will allow PulseAudio to use Roc as a network transport. You can read more about the project in these two articles: 1, 2. The recording controls can be found on the Recording tab.I’m working on the Roc Toolkit open-source project, a development kit for realtime audio streaming over the network. You can control the sound while recording as well. When using VLC Media Player for instance, it will show up in the Playback tab : This can be done by using the corresponding slider. In the Playback tab, you have the possibility to control the sound for individual apps since any running media player application will show up in this tab. By default, Analog Stereo Duplex is the selected. Sound profiles can be changed as well from the Configuration tab. To display specific input devices in case you have several, use the Show drop down menu in the Input Devices tab. Similarly, two sliders will show up when you click on the Lock button : Other input devices (Microphone/Line In/Analog Input/Video) can be selected from the Port dropdown menu in the Input Devices tab. On the Input Devices tab, you can control the sound from the input devices using the slider as shown below : Clicking on the lock button in the Output Devices tab will display two sliders as shown in the snapshot below : PulseAudio allows you to control your speakers separately. To mute or unmute the sound, click on the toggle button as shown below in the Output Devices tab. On the Output Devices tab, you have the possibility to configure the sound output by dragging the slider to the left or to the right. Once you click on the Pavucontrol icon, you will see the following screen : To run Pavucontrol, open up the activities screen and type in ‘pulse’ in the input field as shown below : You can configure sound volume using PulseAudio graphical user interface or frontend which would need to be installed as well.

You can install PulseAudio with the following command:
Pulseaudio manager update#
Now close Software & Updates application and execute the command below in order to update the package repository list: Once you open the application, ensure the the marked checkboxes are ticked as shown in the snapshot below. In order to achieve this using a GUI, look up Software & Updates application by writing ‘software’ in the activities section as shown below. This is because some of the required packages that would need to be installed will be retrieved from software sources. Enabling different Software Sourcesīefore you start, you would need to ensure that main, universe, multiverse and restricted software sources are already enabled on your Ubuntu 18.04. In this tutorial, you will learn how to use PulseAudio in order to Manage Sounds on Ubuntu 18.04. It can alter the sound format, decrease or increase sound channels, send the sound of one machine to another one. PulseAudio has the ability to combine sounds from different sources (aka mixing). It works like a proxy or a sound server which can manipulate the sound before it reaches your ears. PulseAudio handles the sound that is emitted by your Linux application.
