1. You are running an old version of OBS Studio (27.1.3). Please update to at least version 29.1.3 by going to Help -> Check for updates in OBS or by downloading the latest installer from the
downloads page and running it.
2. One of your audio devices has a sample rate that doesn't match the rest. This can result in audio drift over time or sound distortion. Check your audio devices in Windows settings (both Playback and Recording) and ensure the Default Format (under Advanced) is consistent. 48000 Hz is recommended.
OBS Sample Rate:
48000 Hz
Alto-falantes (2- High Definition Audio Device):
48000 Hz
Microphone (2- High Definition Audio Device):
44100 Hz
3. Run updated OBS as Administrator. Right click on the OBS shortcut, properties, advanced, check box, ok, apply, ok.
4. Multiple Game Capture sources are usually not needed (gameplays), and can sometimes interfere with each other. You can use the same Game Capture for all your games! If you change games often, try out the hotkey mode, which lets you press a key to select your active game. If you play games in fullscreen, use 'Capture any fullscreen application' mode.
5. One of the configured encoders is not recognised. This can result in failure to go live or to record. To fix this, go to Settings -> Output and change the 'Encoder' option. Select the QSV encoder. If you updated all the way to version 30 of OBS, you'll probably need to use the old Quick Sync Video DLL. See Replace the .dll from previous working version. See
