HP Laptop 17-by4xxx crackling sound

[An6elOfMercy]

I keep getting a crackling sound from my laptop. Don't think it's coming from the speakers. I updated all of the HP and Windows software but it still crackles. Could it be hardware and which hardware could it be? Thanks.

Hi @An6elOfMercy,

Welcome to HP Support Community. 
Thank you for posting your query, I will be glad to help you.

I see that you are facing crackling sound issues with your HP Laptop PC 17-By4000 (18B35AV).

Please follow the steps listed below:

Step1: Disable Sound Enhancement:

Some sound drivers use enhancements to improve sound quality on your PC. But if enhancements aren’t working well, crackling sound issue could occur. To disable it:  
1) Right-click the sound icon at the bottom right corner of your desktop and select Playback devices.  
2) Highlight your default audio device, which should have a green tick on its icon, then click Properties. 
3) Go to Enhancements tab. Check the box for Disable all enhancements. Then click Apply and OK to save the change.

Note: This option is not a universal one, since not all software drivers include such a function. You may also see a similar tab named Sound Blaster and similar effects. Or you may not see the option the disable enhancements at all.

Step 2. Change Power Settings:
1) On your keyboard, press Windows logo key and then type control in the search box. Select Control Panel from the list. 
2) View by Large icons and then select Power Options. 
3) Select Change plan settings of whichever plan that you’re using now. 
4) Now click Change advanced power settings. 
5) Locate and click the + button to expand Processor power management. Then expand Minimum processor state as well. Change the Setting (%) to 100. Then click Apply and OK to save the change.

I hope this helps.
Take care and have a good day.
