Play Audio Files on a Raspberry Pi with LXMusic

Learn how to install LXMusic on Raspberry Pi OS, add MP3 files to a playlist, control playback, and troubleshoot audio output.

Play local audio on Raspberry Pi

A Raspberry Pi running Raspberry Pi OS can play locally stored audio files, including MP3 files. This lesson uses LXMusic, a lightweight graphical music player for managing playlists and playing local audio.

The focus is desktop-based playback: you will use the Raspberry Pi desktop, Terminal, and LXMusic window. This is different from programming audio output with Python or another programming language.

Key terms

  • Raspberry Pi OS: The operating system environment that provides the desktop, Terminal, package manager, and media player.
  • LXMusic: A graphical music player that can play local audio files and manage playlists.
  • MP3: A common compressed digital audio file format.
  • Terminal: A command-line application used to install software and run system commands.
  • APT: The package-management system used to install software on Debian-based Raspberry Pi operating systems.
  • Playlist: An ordered list of audio tracks prepared for playback.
  • Audio output: The hardware route used to hear sound, such as HDMI, analog headphones, USB audio, or Bluetooth speakers.

Prerequisites

Before installing LXMusic, make sure the following conditions are met:

  • Raspberry Pi OS is running and you can access its desktop.
  • You can open a Terminal window.
  • An audio output is available and connected. Depending on the Raspberry Pi model and setup, this might be HDMI audio, a supported headphone jack, USB audio, or Bluetooth audio.
  • At least one readable audio file is stored on the Raspberry Pi or on storage accessible from it.

For a first test, use a standard MP3 file in a location that is easy to find, such as your home folder or a music folder.

Install LXMusic with APT

APT downloads and installs software packages and their required components. Install LXMusic from the Raspberry Pi desktop:

  1. Open the application menu and start Terminal.
  2. Enter the following command:
sudo apt-get install lxmusic
  1. When APT displays an installation confirmation prompt, type Y and press Enter to approve it.
  2. Wait for the package installation to finish. Do not launch LXMusic until the command has completed successfully and the Terminal prompt has returned.

The sudo part gives the command the administrative privileges needed to install software. You may be asked for the password of your user account.

Launch LXMusic from the desktop

After installation, open the desktop application menu and select:

Menu > Sound & Video > Music Player

LXMusic opens as a graphical music-player application. The exact appearance can vary slightly with the Raspberry Pi OS desktop version, but the application menu category and music-player entry provide the normal launch path.

If LXMusic does not appear, verify that the installation command completed without errors. Search for LXMusic in the application menu, then restart the desktop session or reboot if the menu has not refreshed.

Add audio files to a playlist

A playlist is the collection of tracks that LXMusic has queued for playback. To add music:

  1. Open LXMusic.
  2. Find the add-files control, represented by a plus icon.
  3. Use the file chooser to browse to the folder containing your audio files.
  4. Select one file or select multiple files, then confirm the selection.
  5. Verify that the selected files appear in the current playlist.

You can add a single MP3 for a quick test or add several files to create a queue. Select or arrange tracks in the playlist as needed before starting playback.

LXMusic controls

ControlPurpose
Add files buttonOpens a file chooser so you can add one or more audio files to the current playlist.
Play buttonStarts playback of the selected track or the next queued track.
Pause buttonTemporarily stops playback while keeping the current position. Use play or resume to continue.
Volume controlRaises or lowers the player volume. It may also be necessary to adjust the desktop system volume.
Playlist areaShows the tracks queued for playback and lets you select another track or manage multiple tracks.

Play an MP3 file

To play one local MP3 file:

  1. Open LXMusic from Menu > Sound & Video > Music Player.
  2. Press the plus-shaped add control.
  3. Choose an MP3 file in the file chooser and add it to the playlist.
  4. Select the track in the playlist.
  5. Press the play control.
  6. Use the pause control to stop temporarily, then use play again to resume.
  7. Adjust the LXMusic volume control to set a comfortable level.

To queue several tracks, add multiple files before pressing play. LXMusic can then play the tracks in sequence. Use the playlist area to select tracks and perform common playlist-management operations.

Verify the audio output

Successful playback requires both a playing track and a usable audio route. Check the following:

  1. Confirm that the selected track is progressing in LXMusic rather than remaining stopped.
  2. Check that the player volume is not muted or set too low.
  3. Listen for sound through the intended speakers, headphones, or other device.
  4. Check the Raspberry Pi desktop system volume.
  5. If sound is routed incorrectly, open the desktop audio settings and select the intended HDMI, analog, USB, or Bluetooth output.

For example, a monitor connected by HDMI may be selected when you expected USB speakers. Changing the desktop audio output device should route sound to the selected hardware.

Practical examples

Install a music player

  1. Open Terminal.
  2. Run sudo apt-get install lxmusic.
  3. Approve the installation if APT asks for confirmation.
  4. Wait until installation completes.

Expected result: LXMusic is installed and available from the Raspberry Pi desktop menu.

Play a single MP3

  1. Open LXMusic from the Sound & Video menu category.
  2. Use the plus-shaped add control to browse for an MP3.
  3. Add the file to the playlist.
  4. Select the track and press play.

Expected result: The MP3 plays through the configured Raspberry Pi audio device.

Queue several tracks

  1. Add multiple audio files to the playlist.
  2. Arrange or select tracks as needed.
  3. Start playback and adjust the volume.

Expected result: LXMusic plays the tracks from the playlist in sequence.

Troubleshoot common problems

LXMusic does not appear in the menu

  • Verify that the APT command completed without errors.
  • Search for LXMusic from the application menu.
  • Restart the desktop session or reboot if the menu has not refreshed.

The track is listed but no sound is heard

  • Confirm that playback has started and the LXMusic volume is not muted.
  • Check the Raspberry Pi system volume.
  • Verify that speakers or headphones are connected and powered.
  • Open system audio settings and select the intended HDMI, analog, USB, or Bluetooth output.

An audio file cannot be added or played

  • Confirm that the file still exists and is readable by your user account.
  • Try a standard MP3 file.
  • Check whether the file format is supported by the playback components installed on the system.

The package installation command fails

  • Confirm that the Raspberry Pi has network access if APT needs to download the package.
  • Check that the command was entered exactly as shown.
  • Refresh package information or resolve package-manager errors before retrying the installation.

Exam-relevant summary

  • Use sudo apt-get install lxmusic in Terminal to install LXMusic.
  • Launch it through Menu > Sound & Video > Music Player.
  • Use the plus icon to add audio files to the playlist.
  • Select a track and use play, pause, and volume controls for playback.
  • Verify both player progress and the selected desktop audio output when troubleshooting sound.
