Laptop makes a buzzing sound and freezes up when listening to music and watching videos

Hi, I have an Envy x360 convertible model 15m-cn0012 and my laptop will sometimes freeze up and make a buzzing sound when I play music, watch videos and play games. I've tried several things to keep it from doing this. Including updating the drivers, going to BIOS and checking to see if there were any updates avaiable for my laptop. I have already updated it to the most recent update and it stopped making the buzzing noise for a while but now it's back and I don't know what to do.
