You may see the video, but the audio stays silent. This problem leads many users to look for ways on how to repair capture card audio not working. Sound issues are common, but they can be fixed with simple steps.

Why Capture Card Audio Is Not Working?

Issues with audio can come from many places. Some problems are small and easy to fix. Others may come from system settings. A few may come from hardware or cables. Many users who face capture card audio not working problems find out later that the cause was simple.

The same happens to those who find their device showing capture card no sound or capture card sound not working. In many cases, the problem comes from just one part of the setup. The same applies to users facing HDMI capture card audio not working or HDMI video capture audio not working. Once you know what causes the problem, you can fix it faster.

Common Causes

• Loose or faulty HDMI cables If the HDMI cable is damaged, bent, or loose, it may block audio signals. Video may pass through while sound fails. Cheap cables also fail under pressure.
• Wrong audio input settings in the software If your capture software is set to the wrong input, sound will never pass through. Many recording tools change inputs after updates.
• Muted audio inside the capture software Some apps set the volume to zero without users noticing. If you mute the track by mistake, the issue shows up as capture card no sound.
• Outdated or damaged audio drivers Drivers help the system handle audio. If they are old or damaged, you may hear nothing. This leads to the capture card sound not working and even the HDMI capture card audio not working.
• Faulty USB ports or low power supply Weak USB ports fail under load. They may cut the sound while keeping the video. This is common on old laptops or cheap hubs.
• Conflicts with background apps Apps like mixers, voice tools, or sound enhancers may take control of your audio. This creates HDMI video capture audio not working issues.
• Capture card internal problems Some cards may develop hardware faults. These faults block audio even when the cables are fine. This problem can affect both USB and HDMI devices.
• Source device audio problems The device you record may have its sound turned off. It may have the wrong audio output settings. If the device does not send audio, the capture card gets nothing.

This can look like an HDMI video capture card audio not working.
