Chapter 3. Configuring sound in GNOME

You can configure sound volume and other sound options in GNOME.

3.1. Sound configuration tools in GNOME

In RHEL 9, the PipeWire sound server handles sound output and input. PipeWire lets programs output the audio using the pipewire daemon.

To configure sound, you can use one of the following graphical applications in GNOME:

System menu

The system menu is located in the top-right screen corner. It enables you only to set the intensity of the sound output or sound input through the sound bar. The sound bar for input sound is available only if you are running an application that is using an internal microphone (built-in audio), such as some teleconference tools.

System menu

Settings

Settings provides other general options to configure sound.

Tweaks

The Tweaks application enables you to configure only volume over-amplification.
