Sound distorted in short time only only with power supply connected

[darmax]

In a very short time that I listen to music, movies or otherwise when the internal speakers emit sound, this is reproduced distorted. I have done everything and more to fix it, but it remains.

HI@darmax, Welcome to the HP Support Community!

I understand that you are getting static issues while using the microphone.

Do not worry. I will try to fix the issue.

Have you tried to use the microphones on different computers or devices?

Please perform the below steps and check.

Hard Reset:

1) Shutdown the computer.  

2) Unplug all the Adapter and peripherals connected.  

3) Remove the Battery. ( not for Built-in Battery computer ) 

4) Press and hold down the power button for 15 to 20 seconds.  

5) Plug-in the Adapter and put the Battery back into the computer if it's a (removable battery)

6) Try to turn on the computer and check, If the issue persists continue next step

Here’s a few things you could attempt: 

By default, Windows automatically enables microphones and line-in ports. Use the following steps to set the microphone/line-in port to be the default port and to configure the recording levels: 

1. If the Recording tab in the sound window is not selected, open the Sound window and click the Recording tab using the instructions in Step 1. 

 NOTE: 

Your desktop or notebook PC configuration may include different components then shown here.

1. If multiple microphones or line-in ports are available, select the port that you want to use. Click Set Default to make this device the default audio input device. 

2. If the device you want to use contains a small circle with an arrow pointing down, the device is disabled. To enable the device, right-click the device name and select Enable. 

3. With the device selected, click Properties, and then click the Levels tab.

1. Adjust the slider to 75. 

2. If Mute is on, click the mute button to un-mate the device. The mute button should show as a blue speaker without a red circle. 

3. If Microphone Boost is available, adjust to +20.0 dB. 

4. Click OK to make the changes. 

5. Test the microphone using the instructions in Step 1 to determine if Windows is able to detect a signal for the microphone or line-in being used. If you have performed all the steps and the microphone or source device still does not work, the audio ports or sound hardware on the computer might be bad.
