Fix OBS Studio Audio Popping When Switching Scenes

Sudden audio popping or clicking when transitioning between scenes in OBS Studio is a common issue often caused by media source configurations, sample rate mismatches, or transition settings. This guide provides step-by-step solutions to eliminate these distracting audio artifacts, focusing on optimizing media element behaviors, aligning system audio sample rates, and adjusting transition properties for seamless, professional-sounding stream transitions.

Match Audio Sample Rates

Mismatched sample rates between your operating system, audio hardware, and OBS Studio are the leading cause of pops and clicks during scene changes. When OBS transitions to a scene with active media, a mismatch forces the system to quickly resample the audio, causing a noticeable artifact.

  1. Open OBS Studio and go to Settings > Audio.
  2. Note the Sample Rate (typically 44.1 kHz or 48 kHz).
  3. On Windows, right-click the speaker icon in your system tray and select Sounds (or open the Sound Control Panel).
  4. Under the Playback and Recording tabs, right-click your active audio devices and select Properties.
  5. Go to the Advanced tab and ensure the Default Format matches the sample rate set in OBS (preferably 48 kHz for modern video streaming).

Configure Media Source Behavior

When a scene switches, OBS immediately loads or restarts media sources. If a video or audio file starts at a high volume instantly, it creates a sudden audio spike.

  1. Double-click the problematic Media Source in your Sources dock to open its properties.
  2. Uncheck Restart playback when source becomes active if you want the media to run continuously in the background, which prevents a hard audio start upon switching.
  3. If you must restart the media on switch, ensure Close file when inactive is checked. This forces OBS to clean up the source’s memory allocation, reducing buffer-induced pops when the scene is reloaded.

Implement Audio Crossfades in Transitions

Using a “Cut” transition cuts off the audio of the previous scene instantly, causing a square-wave drop-off that sounds like a pop. Smooth transitions allow OBS to fade the audio naturally.

  1. Locate the Scene Transitions dock in the OBS main interface.
  2. Change the transition type from Cut to Fade or Swipe.
  3. Set the duration to at least 300ms. This duration allows OBS to apply a brief crossfade to the audio sources of both the outgoing and incoming scenes, smoothing out the transition.

Disable Exclusive Device Control

If another application is sharing your audio device, it may temporarily drop its connection when OBS switches active audio channels, resulting in a popping sound.

  1. Open the Windows Sound Control Panel.
  2. Right-click your primary playback device and select Properties.
  3. Navigate to the Advanced tab.
  4. Under the Exclusive Mode section, uncheck Allow applications to take exclusive control of this device.
  5. Click Apply and OK, then restart OBS Studio.
