I've been using OBS for some time now to record videos for YouTube. Everything was working just great. But recently (seemingly after I updated to Windows 10), ALL .mp4 videos won't work. Recording videos in an .mp4 format, no audio. Remuxing the .flv files to .mp4, no audio. I don't understand what the problem is, as I haven't had this problem before. But literally as soon as anything to do with .mp4 comes up, there's literally no audio at all. Before I uninstalled and reinstalled OBS Studio, not even the .flv files had audio. Once I did said uninstall/reinstall, the .flv files audio work again, but still no .mp4 audio. Is there some way I can fix this???? Please help.

Check your videos with VLC to make sure they really don't have audio and it's not just Windows being terrible.

OK, so I just did that and it has audio when I play it with VLC. But, when I load it into Windows Movie Maker (the only editing tool I know how to use/can afford), there is still no sound. Is it literally just anything Windows??? Is there a way to fix that, would you know? Thank you, by the way.

There are other free (and powerful) options for editing, if you wanted to go that way.

I am not 100% sure on this but it is possible that installing the CoreAudio toolkit (which will get you Apple's audio encoder instead of Microsoft's) may help with the problem. Alternatively, you could try changing your audio bitrate to 192kbps instead of the default 160kbps as that uses a different encoder as well. Again, I am not guaranteeing that this will work, but it might.

Thank you so much for helping me. I will definitely try changing the audio bitrate to see if that will help. I will also follow that link and see what else I could do. Thank you so much for being so helpful!! :D
