I am currently using geforce experience to record video for runs, however sometimes it doesn't record audio for no reason. Does anyone have any recommendations for other software I could use?

OBS, and a plugin that can capture application audio (instead of just whole desktop)

thanks mate I will give that a go

OBS actually has application audio capture, it's currently in beta but I use it and haven't had any issues

that has worked a treat thanks a lot waffles
