Fix OBS Audio Sync Issues

In some cases, when you test your stream, the audio and video may be out of sync. When this happens, the video is usually a few milliseconds behind the audio. So you have to adjust the audio delay to match. This takes some testing to get it exact, but you only have to do this once.
It's usually trial and error, increasing and decreasing the delay increments to find the exact time. Using an on-screen "CLAP" is a great way to time it up.
It's also easier to detect if the clap (video) came before the clap noise (sound) by recording and loading the video into a video editor like Final Cut or Premier. This way you can see where the audio spike is in reference to frame when the clap happened and adjust accordingly.
