Importing ANY audio file (even audio files that used to work) into unreal engine 5.4 project makes them have 0 seconds duration

When im trying to import audio file that work everywhere else, they play, work in blender, in davinci resolve, audacity, you name it, but when importing into unreal engine 5.4, the audio file is imported with a 0 second duration, and doesnt play, there is a waveform thumbnail generated for it, but its just the 0 second duration that stops it from playing at all. How do i fix my audio file importing, i have tried clearing the deriveddatacache, still dont work, changing the default audio output on windows, still wont work, ive tried recording the audio using obs and transcoding it to audio, and it still wont work.

Hey there @maxi74x1234! Are you using WAV files with 16-bit encoding? 24/32 don’t seem to work. That seems to be a common issue with sound files being unable to be read appropriately.

wav files, mp3 files, flac files, are ALL imported with 0.00 duration, even mp4 recodings of the audio transcoded to mp3 dont work

That’s interesting. Any Errors/Warnings in the logs upon import? Does this apply to other 5.4 projects or just this one? Does this apply to any other engine version you have on hand to test? If it’s only 5.4, I can’t recreate it so it could be something wrong with the engine installation. If it’s all versions, there’s a different environmental issue at play.

Heres output logs i see that are relevant, bottom 2 lines are where i imported an audio and attempted to play it, the import info says its duration is “0.00” seconds, when the file is definitely not 0 seconds
