Hi@User_13, Welcome to the HP Support Community!

As I understand the Audio is stuck at 100% and also creates a buzzing noise on your computer,

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 
 

What is the product number for your product? Use this link to find it: Click here (Edited)

Have you attempted any steps on your own before posting on the HP Forums?

When was the last time it worked without these issues? Have you attempted a system restore?

Does the issue occur with a headphone or earphone connected to the PC?

While you respond to the above, here are a few things you need to know:

• Try with an external speaker or earphones to identify the issue.
• Reinstall the audio drivers
• Update the drivers using the HP Website: Click here to access.
• Update the BIOS using the above link.

Hope this helps! Keep me posted.
