After setting the attack speed to 20, the 2nd attack sound is not heard when performing a forced attack

A sound is heard during a forced jump attack.

If the attack speed exceeds 7 frames per second, the 2nd attack sound will not be heard. This seems to be because the frame count of attack1-2 is set to 6.

jump attack(action.attack3) sounded normal because the frame count was 8.
