Please help me, I was using Realtek HD sound effect manager in the control panel and tried to change the equalizer. But when i played some music, it already sounded weird and i don't know what to do with it. It has no any undo button. It can't be returned to the way it sounded like before. What can i do about it? Answers will be very much appreciated !
If there are any equalizer presets, you can try using those, otherwise the best you can do is try and remember what you changed and change it back until things sound better. A "safe" default usually is to just set all the bars in the exact middle. It's a flat, but neutral, sound.
