Fix Bandicam Audio Not Working (Quick Fixes)

Recording videos without audio can be frustrating, especially when you've captured gameplay, tutorials, or important meetings. If you notice that Bandicam isn't recording sound properly, the issue usually comes down to simple settings adjustments.

Solution 1: Verify the Record Sound Option

1. On Bandicam, select the Video option. Navigate to the Recorder section and click Settings to open the Record Settings window.

2. Inside the Sound tab, check the Record sound option. Then, select Default Sound Device under Primary Sound Device. Click Save to apply the changes.

Solution 2: Correct Primary and Secondary Sound Device Selection (WASAPI vs. Default)

1. In the Bandicam Record Settings window under the Sound tab, check your Primary Sound Device. Look at Primary Sound Device and Secondary Sound Device options.

2. For system sounds, choose Default Sound Device to have Bandicam follow Windows' default output. However, choose WASAPI for direct sound capture. WASAPI is recommended for higher-quality audio and ensures no echo.

Solution 3: Check Two Sound Mixing Settings (Microphone + System Audio)

1. In the Sound tab, set Primary Sound Device to (Default Output Device). Then, disable Secondary Sound Device (Microphone). Click Save to apply the changes.

2. Right-click Speaker in the system tray, then select Sounds. Proceed to Recording, right-click your Microphone, and choose Properties. Open the Listen tab, check Listen to this device, and click Apply.

This method is useful when direct microphone capture does not work properly, allowing Bandicam to record both audio sources through the system output. (Check here the full guide to record audio in Bandicam along with a microphone.)

Fix Bandicam Audio Not Working (Advanced Windows & System-Level Troubleshooting)

If the basic fixes do not solve the problem, the issue may be related to deeper Windows audio settings or system-level configurations. Sometimes Windows turns off certain recording devices or routes sound in a way that prevents recording software from capturing it properly.

Solution 4: Windows Sound Mixer & Volume Check (Common Muting)

1. Right-click Speaker in your system tray, then select Sounds. Go to the Playback tab and check the status of your devices:

1. Right-click the Speaker in the system tray to open the Windows Sound settings window. In the Sound window, go to the Recording tab.

2. Look for Stereo Mix in the list of recording devices. Right-click Stereo Mix and select Enable. Optionally, right-click it again and select Set as Default Device for compatibility with recording software.

After enabling Stereo Mix, start Bandicam and try recording again. After configuring correctly, Bandicam should now capture your system audio without any issues.

Solution 6: Review Microphone Privacy Settings (Windows 10/11)

1. On Windows, open the Settings and navigate to Privacy (or Privacy & Security in Windows 11). In the left panel, scroll down to the App permissions section and click Microphone.

2. Turn on the Microphone access for this device option. Enable Allow apps to access your microphone. Scroll down and confirm that Bandicam is allowed to use the microphone.

After enabling these settings, restart Bandicam and try recording again. Your microphone should now work properly during screen recordings.
