Recording iPhone game, Can't sync video to audio?

Hello I'm recording my iphone 4s screen with display recorded, there's no lag at all. I'm also using an aux jack to my computer to record the sound through audacity. I'm using Pinnacle HD Studio 15 for my video editing. The problem is i can't get the audio to sync to the video. Every time i play the preview the audio is quite far behind the video, Even though i'm pressing record on my iphone and comp at the same time.

  • Why doesn't the audio show up in my iOS 11 screen recording? I have the beta version of iOS 11 and have been using the screen recording function. However, the audio from what I'm doing on my phone doesn't always show up on the final video. I'm thinking it is just because of the length. I recorded a video about a minute long to test, but the video I tried to record is around 20 minutes. Is this on purpose or is it a glitch? And is there a way I can fix it?
  • IPhone 5 no audio on video recording? Whenever I record video on my iPhone 5 (back camera) the audio will play fine on the playback for about 3 seconds, and then just cut off. I have not yet tried putting the video files on a computer to see if this is the same as I do not have access to a computer.
