Windows 10: mild screen flickering with a low crackle noise from pc speakers

my pc screen randomly flickers by small lines flashing on screen each second or so. i can perfectly see everything on screen but just with a mild disturbance with those small lines as if the cable is not well connected. these flicker lines also join with a low crackling noise from my default audio device output, but not out of my headphones though. note that my speakers are connected to the back sound ports of the pc through RCA and my headphones are connected through the front ports. that too the noise and the flickers come together.I recently updated my graphic drivers so i thought that upda

Crackling noise

Hi,

To better assist you regarding your concern, we would like to ask some questions:

• Is the crackling noise affecting the performance of your computer?

There are many reasons why your computer is having a noise. It can be that your computer's fan or air vent is covered with dust. Cleaning it can help you resolve your concern. It can be that your BIOS is not updated, you can update your BIOS with the help
of your computer's manufacturer.

We're looking forward to your response.

 

Laptop speaker crackling noise problem

Hello,

My laptop has developed a very annoying crackling noise in the right speaker as of late. I started noticing it as I was listening to some music on it, and then it gradually got worse and worse to the point that I couldn't bear it any more. I do not get this problem when I wear headphones, it's just the right speaker acting up. The laptop is new (less than two months old) and still under warranty. At the moment I have turned the speaker off and I am only running off the left one when not using headphones. If anyone has any suggestions I would appreciate it. Also, I don't think it's driver related because the left speaker works flawlessly and I don't get the same annoying crackling sounds when using headphones.

 

Audio from laptop speaker crackles

I have a Dell Inspiron 15 laptop that starting making crackling noises in it's built in speakers last week. It makes the noise when playing any kind of sound. I ran the audio troubleshooter and nothing was found. I rolled back a display
driver update I got a few days before hand but it was still making the noise. I then uninstalled the audio driver and restarted my laptop. When it came back on, the driver came back by itself and it stopped making the crackling noises. But tonight it started
doing it again. I ran the troubleshooter again and it suggested turning off audio enhancements but nothing is checkmarked except "immediate mode". I removed the checkmark but the sound is still crackling.
