OBS Not Capturing Game Audio? Fixes That Work

If OBS Studio is not capturing game audio, the cause is almost always a missing or misconfigured audio source in the Audio Mixer, an incorrect audio device selection, or a Windows audio routing issue. This guide walks you through the most common fixes, from checking the mixer to changing OBS’s audio settings, so you can get your recordings and streams sounding right again.

Why OBS Sometimes Misses Game Audio

OBS captures audio through two main routes: desktop audio (everything your PC plays) and application audio (specific programs via the Windows audio session). When game audio doesn’t appear, it usually means one of these routes is broken. Common culprits include:

• The game is set to a different audio device than the one OBS is listening to (e.g., your headset vs. your speakers).
• OBS’s desktop audio device is set to “Disabled” or the wrong output.
• The game uses exclusive mode, which can block OBS from hearing it.
• Windows audio enhancements or spatial sound are interfering.
• You’re using a capture card or a virtual audio cable incorrectly.

First Check: The Audio Mixer and Sources

Open OBS and look at the Audio Mixer dock (usually at the bottom). If you see a game source listed but the meter isn’t moving, the source is muted or its volume is at zero. If you don’t see the game at all, you’re missing a source.

1. Click the + under Sources and select Audio Output Capture (for a specific app) or Desktop Audio (for all system sounds).
2. For Audio Output Capture, choose the game’s process from the dropdown (e.g., “game.exe”).
3. For Desktop Audio, make sure the device matches your actual output device (e.g., “Speakers (Realtek)” or “Headphones”).
4. Check the speaker icon next to each source in the mixer to ensure it’s not muted.

Fix 1: Set the Correct Desktop Audio Device

OBS has a global setting for desktop audio. If it’s set to “Default” and Windows is sending audio to a different device, OBS will hear nothing.

1. Go to Settings > Audio.
2. Under Desktop Audio, select the exact device you’re using for game sound (not “Default”).
3. Under Global Audio Devices, do the same for the Desktop Audio entry.
4. Click Apply and OK. Restart OBS if the change doesn’t take effect immediately.

This is the most common fix for users who have multiple audio outputs (e.g., speakers and a headset) and Windows switches between them.

Fix 2: Disable Exclusive Mode in Windows

Windows allows apps to take exclusive control of an audio device. If a game enables this, OBS can’t capture the audio stream.

1. Right-click the speaker icon in the system tray and select Open Sound settings.
2. Click Sound Control Panel (on the right side).
3. Select your playback device (the one the game uses) and click Properties.
4. Go to the Advanced tab and uncheck Allow applications to take exclusive control of this device.
5. Click Apply and OK.

This is a reliable fix for games that use exclusive audio (many older titles and some newer ones do).

Fix 3: Use Application Audio Capture (Windows 10/11)

If desktop audio still fails, capture the game specifically. OBS’s Audio Output Capture source listens to a single app’s audio session.

1. Add a new Audio Output Capture source.
2. In the properties, select the game from the dropdown (if the game isn’t listed, start it first, then refresh the list).
3. If the game still doesn’t appear, try running OBS as administrator (right-click OBS > Run as administrator). This gives OBS permission to access protected audio sessions.

Fix 4: Check Windows Sound Settings and Enhancements

Windows audio enhancements can sometimes cause OBS to receive a silent or distorted signal.

1. In the Sound Control Panel (as above), go to the Enhancements tab (if present).
2. Check Disable all enhancements.
3. Also, go to Settings > System > Sound and scroll to Advanced sound options > App volume and device preferences. Make sure the game’s output device matches the one OBS is using.

Fix 5: Reset OBS Audio Settings

If nothing else works, reset OBS’s audio configuration to default.

1. Close OBS.
2. Press Win + R, type %appdata%\obs-studio and press Enter.
3. Rename the global.ini file to global.ini.bak (this stores audio settings).
4. Restart OBS. It will create a new config. You’ll need to re-add your sources, but this often clears hidden audio glitches.

Frequently Asked Questions

Why does OBS capture my mic but not game audio?

This usually means your desktop audio device is set incorrectly or the game is using a different output than the one OBS is monitoring. Follow Fix 1 and Fix 3 to ensure OBS is listening to the right device or app.

Why is my game audio quiet or distorted in OBS?

Check the volume levels in the Audio Mixer. If the game is too loud, it can clip. Lower the source volume in OBS or in the game itself. Also, disable audio enhancements (Fix 4) as they can alter the signal.

Does OBS capture game audio if I use a capture card?

Yes, but the audio comes through the capture card’s HDMI input, not your PC’s desktop audio. You need to add a Video Capture Device source and ensure its audio is set to “Capture audio” (in the properties). Then the audio will appear as a source in the mixer.

Why does OBS not capture audio from a specific game but works for others?

Some games use protected audio streams or exclusive mode. Try running OBS as administrator, and if that doesn’t work, use the Audio Output Capture source for that specific game. If the game still doesn’t show up, it may be using a driver that OBS can’t access.

Can I record game audio and my mic separately in OBS?

Yes. In OBS, add your mic as an Audio Input Capture source and your game as a Desktop Audio or Audio Output Capture source. In Settings > Output > Recording, set the audio tracks so that track 1 has both, and track 2 has only the mic (or vice versa). Then in your editor, you can mix them freely.

Why does OBS show “Audio device not found”?

This happens when the device you selected in OBS is no longer available (e.g., a USB headset was unplugged). Go to Settings > Audio and re-select the current device. If the device is missing entirely, check Windows Sound settings to ensure it’s enabled.
