Why does audio cut out randomly during matches?

Audio dropouts in UE5 games are usually caused by the audio buffer being overwhelmed during high CPU load (large maps, many players). Lowering the audio quality setting or increasing the audio buffer size in Windows resolves most cases.

Is this a Bluetooth audio issue?

Bluetooth headsets are prone to audio cutouts because the HFP (Hands-Free Profile) bandwidth is limited. If using Bluetooth, switch to the A2DP (Stereo) profile or use a wired headset for stable audio.

Audio dropouts during gameplay break immersion and can cost you a round. The sound cutting out is typically caused by audio buffer underruns (the CPU cannot feed audio data fast enough), Bluetooth bandwidth limitations, or driver conflicts. This guide addresses every layer of the audio stack.

Detailed Step-by-Step Fixes

1. Increase Audio Buffer Size

A small buffer causes crackling and dropouts when the CPU is under load.

Right-click the speaker icon → Sound settings.
Click Device properties under your output device.
Click Additional device properties → Advanced tab.
Set Default Format to 24 bit, 48000 Hz or 16 bit, 44100 Hz.
Uncheck Allow applications to take exclusive control.
Click Apply → restart the game.

2. Switch Bluetooth to A2DP Profile

HFP (Hands-Free Profile) limits bandwidth to ~64 kbps, causing audio to cut out when the mic is active.

Open Bluetooth & devices settings.
Click the three dots next to your Bluetooth headset → Device properties.
If available, switch to Stereo (A2DP) mode.
If the option is not available, install the manufacturer’s Bluetooth driver (not the Windows generic driver).

3. Disable Audio Enhancements

Audio enhancements (bass boost, spatial sound) can cause conflicts with UE5’s audio engine.

Open Sound settings → Device properties → Additional device properties.
Go to the Enhancements tab.
Check Disable all enhancements.
Go to the Spatial sound tab and set it to Off.
Click Apply and restart the game.

4. Update Audio Drivers

Outdated Realtek, Conexant, or USB audio drivers can cause buffer underruns.

Open Device Manager.
Expand Sound, video and game controllers.
Right-click your audio device → Update driver.
If Windows Update does not find a newer version, visit your PC/motherboard manufacturer’s website for the latest driver.

Platform-Specific Solutions

Steam Deck

Steam Deck uses a built-in audio codec that is generally stable. If audio cuts out, go to Desktop Mode → KDE System Settings → Audio and verify the output device is set correctly. Switch between the internal speaker and headphone jack to reset the audio pipeline.

Mac (CrossOver / Wine)

CrossOver’s audio translation (via pulseaudio or ALSA) can introduce latency and dropouts. Use the Wine PulseAudio driver in your CrossOver bottle settings. Avoid using macOS Bluetooth audio with CrossOver — use a wired USB headset instead.

Advanced Troubleshooting

If audio cuts out only on specific maps, the map’s audio assets may be corrupted or too large for your system. Verify game files via Steam (right-click → Properties → Installed Files → Verify integrity). For persistent issues across all games, see Audio Stuttering Bluetooth.
