Google Keyboard Typing Sounds Issue

I use Google Keyboard, and I have an issue. When I type, I get vibration feedback for each of the keys I press. However, that's not the case for the sounds. I type fast, and I only get a keypress sound for some of the times I press the keys. For example, if I type HELLO, I hear 3 keypress sounds instead of 5. Anyone knows how to solve this?

Thanks :o
