All set to host a mind-blowing live stream on OBS? You prepare the perfect green screen setup and look into all the necessary technicalities beforehand so can ensure a smooth experience, but suddenly encounter issues with audio capturing?
Nothing can be more frustrating than this! But not to worry, it isn’t as big an issue as it may seem and we got you covered in this article, discussing each step clearly so you can knock off the issue for good. But before we troubleshoot the problem, let’s understand what the concern is.
Knowing the Problem
A capture card is supposed to record both the video and audio from the source device when used with OBS. However, occasionally you could come across a circumstance where the video is properly recorded but the audio is absent.
Hardware connections, programme configurations, or compatibility issues are only a few causes of this difficulty.
Steps for Troubleshooting
A capture card is a piece of hardware used with OBS that records and copies external audio and video sources before sending them to your computer for broadcasting, recording, or live streaming.
When incorporating external devices, such as gaming consoles, cameras, or other PCs, into their broadcasting or recording setups, content producers, gamers, and broadcasters frequently use capture cards.
Working on Capture Card
- External Source: An external source device that produces audio and video, such as a gaming console (such as the PlayStation or Xbox), a video camera, a Blu-ray player, or another computer, is connected to a capture card.
This external source often uses HDMI, component, composite, or other video output techniques to send out audio and video signals.
- Connection to the Capture Card: The external source’s output ports are matched by the capture card’s input ports. The HDMI output of your gaming console, for instance, would be connected to the HDMI input of the capture card using an HDMI cable.
Additionally, the capture card is linked to your computer using an appropriate interface like USB, PCIe, or another.
- Capturing of Video and Audio: The capture card accepts audio and video signals from an external source and transforms them into digital data that your computer can use. This procedure makes sure that the external source’s audio and video are concurrently recorded and delivered to your computer.
- Integration with OBS: In OBS, you may add the capture card as a source for both video and audio. This enables you to view and hear the external source’s content inside of OBS. Then, for purposes of live streaming or recording, you can incorporate this source into your OBS scenes.
Why is this Issue Happening
- Check that any wires connecting the capture card, an external source (such as a gaming console or camera), and your computer are safe and linked to the appropriate ports.
- Check the capture card’s compatibility with your computer’s operating system and make sure it can handle the video and audio formats of the external source.
- Install the most recent drivers for your capture card from the manufacturer’s website if you have any outdated drivers. Compatibility problems may result from outdated drivers.
- In OBS, double-check that the input source you’ve chosen for your capture card is the right one. Select the source you want to capture from any connected sources to the capture card.
- Verify that your capture card, the external source, and OBS all have the same audio sample rate settings. Audio synchronization difficulties can be caused by a mismatched sample rate.
- The operation of the capture card in OBS may be hampered by other software that is running in the background, such as video conferencing or screen recording programs. Any unneeded background programs should be closed.
- Some security programs could prevent or obstruct the use of capture cards. Verify that OBS or the capture card drivers are not being interfered with by your firewall or antivirus software.
- On occasion, OBS may not function properly with a certain driver version. Try several driver updates, or ask the manufacturer of your capture card what drivers they recommend.
8 Solutions to Fix Audio Not Capturing on Capture Card

- Then, on the right side of the window, there is ‘source’, click on it and select the option for ‘properties’.
- From here, try deactivating and reactivating the source.
Solution 7 – Check Your Hardware Connections
- A secure connection between your source device and the capture card should be made using the audio cords. To make sure the cable is connected properly, inspect both ends.
- Check that the capture card is correctly installed into the PCIe slot on your computer, and make sure that all of its connections are safe.
- Check the audio output options on your source device. Depending on your system, make sure the audio is set to the proper output source, such as HDMI or analog audio.
Solution 8 – Check Your Audio Sources
If you have access to different gaming consoles or cameras as sources, try using those instead of your capture card to see if the audio problem still exists. This will assist in determining whether the issue is unique to the source device.
