No Sound in Editor and in Game

Hello, everyone:

I am developing in Unreal Engine 4.26 version, but today after packing work, the packing fails and than the sound cannot be played in the project. I also suspect that it was changed to something. I can’t hear any sound when playing any audio in editor and in game, nor does it appear in the Windows volume mixer.

But I can hear the sound normally after opening other projects. But I still can’t play any audio assets in my project. This is a very strange problem. I don’t know what went wrong, and the settings seems are all set correctly. If you can help me know what the problem might be, I would be very grateful.

Hello! I’m right now in the same scenario, after a packaging error I cannot play any sound in editor nor gameplay. It doesn’t even appear in the windows sound mixer.

Have you came out with a solution along this time?
