Audio in SWF file works, but no audio in MP4
I am currently attempting to upload a video to YouTube, and I've been having a weird problem. I imported a voice line from OBS after allowing it to meet the necessary sample rate requirement (44.1 kHz) as a WAV file, and, in the SWF file, I can hear the audio. However, when I went to import the video, the MP4 doesn't play the audio at all. What's strange is that there are also some sound effects in there that do play. Everything works right except for that voice line. How can I fix this?
