League of Legends Sound Not Working? 8 Fixes for No Audio

If League of Legends sound is not working but other apps still play audio, the cause is usually a muted app channel, the wrong Windows output device, disabled in-game audio, or a driver/service problem. Work through these fixes in order and stop when sound returns.

Riot's current troubleshooting guidance focuses on the playback device, in-game audio settings, drivers, and surround sound. Microsoft also recommends checking per-app volume, output routing, Windows Audio services, and drivers when one application is silent.

1. Check League of Legends in the Windows Volume Mixer

League can be muted independently from the rest of Windows. Launch League and enter a game so the game process is active, then:

Right-click the speaker icon on the taskbar and open Volume mixer.
Find League of Legends or the active game process.
Make sure it is not muted and raise its app volume.

Windows Volume Mixer with League of Legends volume turned up — Make sure League of Legends is not muted or set much lower than other apps in the Windows Volume Mixer.

Microsoft lists per-app volume as a first-line fix when system sounds work but one app does not: Fix app audio not working while system sounds work.

2. Select the correct Windows output device

If you switch between speakers, a monitor, Bluetooth audio, USB headsets, or a dock, Windows may send League audio somewhere else. Open Settings > System > Sound and choose the device you are actually using. If app-specific routing is available in Volume Mixer, verify League is not assigned to another output.

Windows Sound settings with a USB headset selected as the output device — Confirm Windows is sending League audio to the headset or speakers you are actually using.

3. Check the headset, speakers, and hardware controls

Turn up the headset or speaker volume, reconnect USB or 3.5 mm plugs, and try another port if available. If a headset has separate game/chat balance controls, center them temporarily. For Bluetooth devices, confirm Windows is using the normal playback device you expect.

Gaming headset with a physical volume wheel and microphone mute button — Check hardware volume controls as well as the playback connection; a microphone-mute button affects voice chat, not game sound.

4. Check League's in-game Sound settings

Open a game, press Esc, and select Sound. Make sure Master Volume and the sound categories you need are above zero, and confirm Disable All Sound is not selected.

League of Legends Sound options with volume sliders above zero and Disable All Sound unchecked — Keep the master and individual sound sliders above zero and leave Disable All Sound unchecked.

Riot recommends these checks in its official League of Legends Sound Issues guide.

5. Disable surround sound and audio enhancements as a test

Riot notes that surround sound can route effects to rear speakers that are not actually present, making some sounds seem missing. Windows audio enhancements can also interfere with playback on some devices.

Open the playback device's properties and temporarily disable enhancements, spatial sound, or virtual surround. Restart League and test again. If sound returns, re-enable features one at a time.

Windows speaker properties with audio enhancements disabled and spatial sound turned off — Disable audio enhancements or virtual surround temporarily if some League sounds are missing or routed incorrectly.

6. Restart Windows Audio services

If League is still silent, restart the Windows audio stack:

Press Windows + R, type services.msc, and press Enter.
Right-click Windows Audio and choose Restart.
Restart Windows Audio Endpoint Builder too, then reopen League.

Windows Services console with Windows Audio selected and the Restart command visible — Restart Windows Audio if the audio service appears stuck while League continues to run.

7. Update or reinstall the audio driver

Avoid old instructions that assume every PC uses a Realtek device. In Device Manager, expand Sound, video and game controllers, choose the audio device your PC actually uses, and select Update driver.

Microsoft recommends Windows Update first for current audio drivers. If updating does not help, uninstalling the audio device and restarting Windows can reinstall its driver automatically.

Windows Device Manager with an audio device selected for a driver update — Update or reinstall the audio device your PC actually uses rather than assuming every system has the same sound hardware.

See Microsoft's current Update audio drivers in Windows instructions.

8. Repair League files in the Riot Client

If Windows audio works normally and League alone remains silent, repair the game before reinstalling it:

Sign in to the Riot Client.
Open your profile menu and select Settings.
Select League of Legends.
Choose Repair and follow the prompts.

Riot Client settings showing the repair option for League of Legends game files — Riot's current client includes a Repair option that scans for missing or corrupted League files.

Riot documents this path in the Riot Client Full Repair Tool guide. If repair fails, use Riot's current uninstall and reinstall instructions instead of older Control Panel-only steps.

If only League voice chat is silent

If game music and effects work but party voice does not, verify the Windows playback device first, then check the League client's Voice settings. Riot notes that the client lets you choose the microphone input, while what you hear follows the system playback device.

For Windows compatibility, Riot currently lists Windows 10 build 19041 or newer and Windows 11, with Windows 11 recommended. The latest requirements are on Riot's League system requirements page.
