Sometimes the audio is delayed or move ahead from the video as a result, and the output is annoying and hard to understand or engage the viewer.

  • Open the OBS Audio Mixer click on the gear icon on the source audio file.
  • Select the Advanced Audio Properties from the drop-down menu next to the Properties option.
  • After that, enter the delay time in milliseconds under the Sync Offset option. Then, please change the time according to your video (it may take some time to enter the correct millisecond).

It is one of the common issues, and there may be a technical reason behind the issue, but the issue can be fixed from the setting to the sound devices to 48 kHz, or 44.1kHZ is the only sample rate that OBS supports.

  • Open Settings in OBS software under the control section.
  • Now click on the Audio from the settings menu.
  • Then go to the general to change the sample rate to 44.1 kHz and then check the output and if somehow it won’t work, then change the sample rate to 48 kHz.
  • After the change is made, move to your system’s control panel and then click on Sounds Settings.
  • Then scroll down and click on More Sound Settings under the Advanced section.
  • Next, select the audio device you are using and click on properties.
  • Under the Properties section,¬† navigate and click on the Advanced Tab and change the default rate to 24 bit 48000Hz (Studio Quality).
  • Repeat the above step to all installed audio devices. However, if the 48000 Hz sample rate is not available in the list, then switch it to 44.1 kHz.
