Noticable Click when looping Audio Waves in UE 5.4

We have quite a few looping engine and jet sounds in our game. They were all looping fine with UE 5.3, but with 5.4 many of them now have a clearly noticeable “click” when the loop happens.

It’s definitely not source file related. The WAVs are clean loops built with Adobe Audition and every other tool or source plays the loops fine. Only UE 5.4 makes them click.

It doesn’t matter if the WAV is set to “loop” or if the loop is defined in the CUE. There’s always a click and no matter what I do, I can’t get rid of it.

I know that this simple feature of letting sounds loop seamlessly has been an issue with UE ever since 5.0 (do a search for it on this forum), but after investing hours, I’ve always found some work-around. Not this time. The click remains no matter what I try to fix it. HELP!!!
