HP Envy x360 has made a siren like noise, while I was on a zoom meet and google classroom.

I had to recently recently fixed my audio issues with this laptop.  I was having issues of no audio.  I troubleshooted and fixed it using this site.  However, since I did this, I have issues with my laptop making a terrible siren noise in the middle of a google meet or zoom meet.  I am not able to reset the computer,  as it isn't responsive to the ctrl alt delete method, so I had to turn off the laptop by using the on/off button.  Why is this happening?  Anything I can do to fix this?
