My composition frame rate is 24 and when I match my preview settings (playback) to 24 , it sounds low pitch and slowed down. But when I put my preview settings to 29.97 (while my comp is at 24 frame rate) , it sounds normal. So when I render my edit, it doesn’t matter what frame rate I render at, it is always low pitch and slow. How do I render my composition so it sounds normal?

It's a good idea create comps by dragging the footage onto the create composition icon in the Project Panel, this will make sure that composition inherets all the attributes of the footage. But...
