Are you sure you really really have actual 24p? Because 23.976 is often called 24p, though technically it is not.
24p is the frame rate for film (real film), which typically has matching audio at 48048Hz. This is because American TV shows film at 23.976, slightly slower like 29.97, so the audio can be played back at 48000Hz to match.
Note that with AssumeFPS it doesn't adjust the audio, so you'd either want to AssumeSampleRate(48000) if you have 48048Hz audio, or otherwise SSRC(48000) to sync up the audio. If you really want to do that.
