No sound in UE 4.7


I recently installed the latest preview update for UE 4.7 but have since then been unable to get any sort of audio working in the engine. Sounds won’t play in the content browser and there is no more audio in-game at all. I am also unable to modify the volume in the volume mixer because the program seems to have disappeared from the list. Here is a screenshot of the problem:

I don’t know if I messed something up somehow but I hope someone knows how to fix this.

Hi Legion91,

The 4.7 Preview 5 has a few known issues, which you can read about here:

Included among these is this:

UE-8875 - No audio playback in the editor

This has already been fixed internally, and should be working in the next preview build.

Hi there,

I’m having the same problem on my end. But just to clarify, it’s not just the sound in the editor that is missing - the in-game sound is gone as well. For me this happened when going from preview 4 to preview 5 of the 4.7 version.

Is there any way to go back to preview 4? I’m currently in the process of implementing sound, so it’s not very good timing for me to not have any sound in-game.

Hi Hejden,

Yes, the bug includes all audio from the editor, including during play.

There is no way to revert to an earlier version of the Preview binary. Preview 6 is not far off, though, so you won’t have long to wait. Generally it is not a good idea to do your main development in a Preview build; they are out so the community can get a feel for new features and give us feedback and bug reports, but they can be released with many bugs.

Thanks Ben,

Yes, I will certainly be more careful when installing preview builds in the future. I guess maybe you’re not in a position to give me an exact date for the next update, but would you say that we are talking days or is it rather weeks?

Things can change very quickly here as far as release dates are concerned, but probably days rather than weeks.

Got it guys.
You need to do:

  • first lounch it with a button in the editor


  • then you play a game in the editor
  • close it and open you project folder
  • lounch exe version and this is it. You should probably see that some files were added because you launched the game

this is it guys. Thanks!
