Hi there
Welcome back to the HP Support Forums! I understand that your are having audio issues. I am happy to give you a hand with this.
Please post the full product number of your computer. See the following, if you need help with that information. HP Desktop PCs - How Do I Find My Model Number, Serial Number or Product Number?
Are all of your drivers up to date? You can try using the HP Support Assistant for now to check for driver updates. HP PCs - Using HP Support Assistant (Windows 10, 8, 7)
Please let me know whether that works for you, and if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.
