This article is about how to install and use PulseAudio sound server under Linux. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

PulseAudio is a sound server where a background process accepts sound input from one or more sound sources (processes or input devices) and redirects sound to one or more slots (sound cards, remote network PulseAudio services, or other processes).

Install Paprefs

The easiest way to enable audio playback from multiple sources is a simple graphical tool called "paprefs". It is the abbreviation of PulseAudio Preferences.

The software is included in the Ubuntu repository and can be installed directly with apt.

Sudo apt install paprefs

After installation, you can start this program.

Start dual audio playback

Although the tool is graphical, it's probably easier to start it as a normal user by typing paprefs on the command line.

The window that opens has tabs with settings that can be adjusted. We choose the last tab here, "Simultaneous Output."

There is nothing in this tab, just a check box to enable this setting.

Next, turn on the general sound preferences. This is located in different locations in different distributions. On Ubuntu, it is within the GNOME system setup.

After opening the sound preferences, select the "output" tab. Check the Simultaneous output radio button. Now it's your default output.

Test it

You can test with whatever you like, but it's always possible to play music. If you are as suggested earlier, there is no problem with testing with video.

If all goes well, you can hear a sound coming from all the connected devices.

That's all that needs to be done. This feature works best when there are multiple devices, such as HDMI ports and standard analog output. Of course, you can also try other configurations. You also need to note that there is only one volume controller, so you need to adjust the physical output device according to the actual situation.
