Why Can’t I Hear Audio When OBS Is Open? 

If you are using more than one output device, have installed multiple audio drivers like Realtek and NVIDIA, are using the audio monitoring feature, or your default audio is not selected, then OBS will detect more than one device and, as a result, your PC won’t be able to play any sound.

Audio Monitoring: This feature allows you to use headphones to listen to your audio while recording. This feature could cause hurdles between the input and output devices and may disable the sound of all other devices.

More than One Output Device: If you are using more than one output device like speakers, headphones, or Bluetooth speakers, then you might have to use only one device.

Administrative Permissions: OBS requires administrative power to control many features, including audio devices. If its unable to get permission, it is more likely to restrict many functions, including audio from other devices.

Bluetooth Interference: Some Bluetooth devices can be connected to more than one place. It can cause interference and may disable the sound from your devices.

Turn Off Audio Monitoring

The audio monitoring feature allows you to hear your audio while recording. If audio monitoring is turned on, then it might disable all other devices to interfere with the audio. It may result in no sound or low-quality audio. You can access the Audio Monitoring option by going to OBS Settings.

Disable Other Global Audio Devices

OBS has a feature that has two desktops and four auxiliary or microphone devices at the same time. This feature makes it easy to broadcast or screen share with your friends. It also enables you to connect studio microphones and headphones at the same time. 

The global audio devices feature interferes with the audio from other devices. It could lead to no sound from your speakers or headphones. You can disable all global audio devices in OBS to see whether the issue is resolved. Here’s how to disable it,

How do you identify which one is your audio device to select the right one in OBS to avoid this audio restriction issue? To determine your windows default device, you have to go to windows audio settings. Let’s first find the default device,

  • Right-click on the “Speaker icon” on the Windows taskbar and then click on “Sound” to access sound settings.

  • Now open OBS and go to “Settings,” then go to “Audio” settings. 
  • Select the global audio device, which one is the default device. 

Change Stereo to Mono

Stereo and mono are two types of audio channels. Mono has a single channel, while stereo audio has two separate channels for input and output. Stereo sound is usually preferred over the mono sound. That is why the default audio is set to stereo in OBS Studio. 

But this could be the root of your No Audio issue. If you are using a mono speaker and the settings in OBS are set to stereo, then it might disable all output devices and restrict audio coming from all other Windows programs. Here’s how you can disable your audio,

  • Open OBS settings and go to “Audio” from the left option bar.

Run OBS as Administrator

Like many other applications, OBS requires administrative resources to collaborate with system applications and programs. If you don’t allow these resources, OBS will not be able to access the Windows audio devices and may restrict them. So, when you open OBS, other apps’ audio will stop.

  • Right-click on OBS studio’s icon and select “Run as administrator.”
