a speaker problem on hp Pavilion 15

[Mahmoud__]

I'm having trouble with scratchy/distorted audio on hp Pavilion 15 ec00 and am wondering if this is just inherent to the design or if my machine has a hardware problem.

When my machine was brand new out of the box, it sounded like the speakers were blown out when playing certain frequencies such as the Windows 10 notification tone. I did the standard troubleshooting by the windows troubleshooter and checked my drivers if there is any driver update but the drivers are updated.

When audio plays I can feel the laptop vibrating and rattling it seems like the strange noise is coming from the right speaker more than the left one.I know this is a laptop and I'm not expecting the world's greatest sound, but the distortion is really annoying. Is this just inherent to the hp Pavilion 15 ec00 or am I just unlucky ? I've tried updating drivers and the problem persists. Headphones are fine. It's definitely the external speakers on this laptop that are vibrating around.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

1. Download the latest version of the HP PC Hardware Diagnostics for Windows, go to the HP Hardware Diagnostics website.

2. In the HP PC Hardware Diagnostics Windows section, click Download Diagnostics Windows, and then follow the on-screen instructions to download and install the software.

3. In Windows, search for HP PC Hardware Diagnostics Windows, right-click the app in the search results, and then select Run as administrator.

   

   The HP PC Hardware Diagnostics Main Menu displays.

   

4. Click Component Tests.

   

5. On the Component Tests menu window, click Audio, and then select Audio Playback Test.

   

6. Click Run once.

   

7. Click Next, and then select an audio playback device to begin the test.

   During the test, a few music notes play in sequence and repeatedly.

   

8. When the Audio Test completes, click Yes or No, depending on what you heard during the audio test.

   

   The audio test results display on the screen.

   

   • If the audio test result passes, click Finish, close the tool, and then restart the computer.

   • If the audio test fails, write down the failure ID (24-digit code) so you have it available when you contact HP Customer Support. This information is also available in Test Logs.
