Stop extremely loud screeching noise after I tried to increase the volume for UTube on my Notebook

[gree1718]

I was trying to increase the sound.  I clicked on something and made it 100 time worse.  The sound is a horrible excremely loud screeching noise that will only go off when the computer is totally turned off.  I tried to go back in and follow the troubleshooting but again it gave me a choice and I chose the wrong one and again the horrible sound started.  I could not shut the computer down fast enough.  Has that happened to anyone else?  If so I will be eternally grateful for any assistance.  Thank you

Welcome to HP Support Forums. 🙂

Thank you for posting on HP Forums, MKazi is at your service. 

I understand that you have an HP Envy TouchSmart 15 series laptop and it makes a loud screeching noise that will only go off when the computer is totally turned off. Not to worry, I'll be glad to assist you with this case.

I would like to know the following information to assist you better:

• What is the exact laptop model number. This link will help in finding the model number: https://support.hp.com/in-en/document/c00033108
• Did any hardware changes or updates happen on the notebook recently?
• Do you have external speakers to connect to the notebook and check if the audio is alright?
• Does the loud noise appear as soon as you power on the laptop or only when you play something?

While you respond to that. I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Power off the laptop.
• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop. 
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.
• Power ON the laptop.

Let us run a hardware test on the audio by following the below steps:

• Shutdown the laptop.

• Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

• On the main menu, click Component Tests.

Figure : Selecting Component Tests from the main menu

• The Component Tests menu displays. Your Component Tests menu might be different, depending on the components installed on your computer.

Figure : Sample list of Component Tests

• Audio Test - The Audio Playback Test checks your system to make sure the audio device is functioning properly. During the test, a few music notes are played in sequence and then repeated. This test takes 1 minute to complete.

  To run the test, click Audio, and then click Run once. Choose either the speakers or the headphones. When asked, enter the number of notes you heard.

I the loud noise appears while running the hardware test then it indicates towards a hardware issue. However, if the audio test passes then you may perform the steps from the HP troubleshooter guide which helps in fixing most of the audio issues.

I genuinely hope the issue gets resolved without hassles and the unit works great. Let me know how it goes. 

All the best! 🙂
