Stop sound commands dont work after repeating same action 2 times

Im making a huge html5 canvas project. I have noticed something. I have some sounds playing. One sound plays then when user clicks on the button another one plays. If i click back the second sound turns off and the first sound plays. If i repeat this 2 times the second sound dissappears for some reason. This occurs only when open the file locally. This is not happening when opening through Adobe Animate. Why? Should i provide which codes i use?
