Fix OBS Audio Popping When Switching Scenes

Audio popping or clicking sounds when switching scenes in OBS Studio can ruin the professional quality of your live stream or recording. This issue typically occurs due to sample rate mismatches, abrupt audio cutting from media sources loading or unloading, or hardware buffering lags during transitions. This article provides a straightforward guide to diagnosing and resolving these audio popping issues by adjusting your scene transition settings, configuring media source properties, and aligning your system’s audio configurations.

Match Audio Sample Rates

The most common cause of audio popping in OBS Studio is a mismatch between the sample rates of your hardware devices, operating system, and OBS itself. When OBS switches scenes and initializes a new audio source at a different rate, a digital click or pop occurs.

  1. Check OBS Sample Rate: Go to Settings > Audio. Note the sample rate (usually 44.1 kHz or 48 kHz).
  2. Check Windows/macOS Sample Rate:
    • On Windows, right-click the speaker icon in your system tray, select Sound settings > More sound settings (or Sound Control Panel). Go to the Playback and Recording tabs, right-click your active devices, select Properties > Advanced, and set the Default Format to match your OBS sample rate (e.g., 24-bit, 48000 Hz).
    • On macOS, open Audio MIDI Setup and ensure your input and output devices are set to the same format (e.g., 48,000 Hz) as OBS.

Use Global Audio Sources Instead of Scene-Specific Sources

If a media source or microphone is only added to specific scenes, OBS will completely shut down and restart the audio driver for that source when you transition. This sudden state change causes an audible pop.

To fix this, configure the audio device as a Global Audio Device: 1. Go to Settings > Audio. 2. Add your microphone or desktop audio device under the Global Audio Devices section. 3. Remove the individual audio input/output sources from your specific scenes. 4. Use the Audio Mixer to mute or unmute sources as needed, or use the Source Dock to control visibility.

Adjust Media Source Transition Settings

For video clips and background music tracks embedded directly in scenes as “Media Sources,” the abrupt start and stop of the file can cause audio artifacts.

  1. Double-click the problematic Media Source in your Sources list.
  2. Uncheck Close file when inactive. Keeping the file loaded in the background prevents the audio engine from abruptly initializing the file when you switch to the scene.
  3. Look for the Show transition behavior dropdown and set it to Fade In instead of “Cut” or “None”.
  4. Ensure Speed is set correctly, and test if checking or unchecking Use hardware decoding stabilizes the audio processing during transitions.

Apply a Fade Transition to Audio

If you are using standard scene transitions (like Cut or Fade), the audio transition might be too sharp. You can adjust how OBS handles audio crossfades during scene changes.

  1. In the Scene Transitions dock, click the gear icon next to your active transition (e.g., Fade) and select Properties.
  2. If available, adjust the transition duration to at least 300ms or 500ms. A longer transition allows OBS to smoothly crossfade the audio levels between the outgoing and incoming scenes, eliminating abrupt digital clicks.
  3. Alternatively, install the Transition Audio Overrides plugin for OBS, which gives you dedicated control over how individual source volume levels fade in and out during transitions.
