Method 2: Select the Correct Desktop Audio Device in OBS

🔍User case: Useful when your audio settings don't match your output device (headphones, speakers).

If OBS is set to an inactive or incorrect device, it won't capture audio.

🚩How to select the correct audio device in OBS:

Step 1. Open OBS and go to "Settings" > "Audio".

Step 2. Under the "Global Audio Devices" section, choose your active playback device for "Desktop Audio."

Step 3. Click "Apply" and restart OBS.

Method 3: Make Sure Audio Monitoring Isn't Set to Monitor Only

🔍User case: Applies if you can hear the audio live but it's missing from the recorded file.

The "Monitor Only" setting plays audio locally but doesn't include it in recordings or streams.

🚩How to change monitoring settings in OBS:

Step 1. In OBS, go to the "Audio Mixer" and click the "gear" icon next to your audio source.

Step 2. Select "Advanced Audio Properties."

Step 3. Change the "Audio Monitoring" option to "Monitor and Output."

Method 4: Match OBS Sample Rate and Adjust Output Settings

🔍User case: Applies when you see the mixer level move, but still no sound in playback.

Mismatch in sample rate or improper bitrate settings can disrupt audio encoding.

🚩How to match sample rate and fix output settings in OBS:

Step 1. Go to "Settings" > "Audio", then ensure Sample Rate is set to "44.1 kHz" or "48 kHz".

Step 2. Navigate to "Settings" > "Output". Set "Output Mode" to "Simple."

Step 3. Set "Audio Bitrate" to "128" and "Recording Quality" to "Same as stream." Click "Apply" to save changes

Method 5: Update or Reinstall Your Audio Drivers

🔍User case: Best for systems that recently updated OS or hardware.

Outdated or corrupted drivers can block OBS from accessing the system's audio feed.

🚩How to update audio drivers in Windows 10 or 11:

Step 1. Press "Win + X" and select "Device Manager."

Step 2. Expand "Audio inputs and outputs," right-click your audio device, and select "Update driver."

Step 3. Choose "Search automatically for drivers."

Method 6: Restart or Reinstall OBS Studio

🔍User case: Applicable when other fixes don't solve the issue.

Sometimes, a glitch or incomplete update can cause OBS to misbehave.

🚩How to restart/reinstall OBS:

Step 1. Firstly, launch the "Control Panel" and hit "Uninstall a Program under the "Programs" section." You will see a new window for "Programs and Features."

Step 2. Now, search for the "OBS Studio" to checkmark and right-click the program to uninstall.

Step 3. Later, open the official website of OBS to download & install the program again. Make sure the problem is resolved or not.

Resetting OBS clears misconfigurations and reverts all settings to default.
