 ffmpeg writes PCM_S24LE to MP4 as is but ipcm atom reports PCM_S16LE.
 As the result the audio stream is totally damaged.
 The same behavior for PCM_S24BE -> PCM_S16BE and 32-bit PCM audio.

 ffmpeg version: nightly build 20230507

 How to reproduce:
 {{{
 % ffmpeg -i input.mp4 -c:v copy -c:a pcm_s24le output.mp4
 }}}
