No sound is output.

[Booooom]

Background music is normal.
However, no sound effects are output. Symptoms are the same after you reinstall the game. Celceta also has the same symptoms.

However, Felghana and ys 6 are output normally.

OS: Windows 10 Home

Please help me.

Run the game in windowed mode, and check the volume mixer. If the master volume and game volume are both turned up, and it shows sound from the game, I’d say check your audio settings in your control panel.

If you play the .wav file in the se folder in the path where the game is installed, you will not hear any sound. I do not know what's wrong.

If background music is normal, did you check the audio settings in-game (didn’t read that the first time around)?

If that’s all good, do you have any other programs running at the time? For example, mouse/keyboard/headphone software, those can interfere.

Finally, are you playing in fullscreen, or windowed mode. Try whichever one you’re not currently in. See if that does something.
