So I record videos with the display capture feature of Obs studio but sometimes the video comes out without any audio, which is very unfortunate. I always use the same notebook and I don't really change the setting. So I don't know why some videos don't have any audio when my other recordings comes out with normal audio, it just happens suddenly. So I'm not sure if the audio is not recorded at all or if there is something wrong. Does anyone have any idee why this keeps happening or how it can be fixed. And is it possible to recover the audios of the already recorded videos?
