Windows 10: Crackling sound in my speaker

I had no issues with my speaker sounds until today. Today I transferred an audio file from my phone to laptop, I haven't opened that audio file yet. I did record a sample directly with my laptop microphone to audio software I downloaded months ago called audacity. Now my speakers have a crackling sound when I listen to youtube. I never had that problem before. What could have gone wrong?

Realtek HD Audio latency leading to crackling sounds from the speakers

I have a problem with the Realtek HD Audio speakers driver. Everytime a sound is about to be play, the speakers of the laptop make a crackling sound, similar to the sound of static electricity.

I am using Windows 10 and have the latest version of the Realtek HD Audio driver.

I ran the Latencymon v 6.50 to check for latencies, and I get the following result:

"Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one problem appears to be network related. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates."

These results appear to be spot-on, however I'm surprised it mentions that at least one problem is network related, since I have the latest network drivers, and even when disabling the network adapters I still get the crackling sound.

I reckon the CPU throttling mentioned is related to the CPU exectution cap which I already set to 100%.

The other thing I need to mention is that this is a new laptop, and from the first day, even with the old drivers I noticed the crackling sound, and I assumed it would go away after I updated the drivers. I have all the newest drivers and I still get this problem.

The funny thing is that when I plug-in the laptop, it somehow does not give the crackling sound, but when I approach my ear to the speakers, I hear that they are on, even when nothing is playing ( I know because they emit some kind of barely distinguishable white noise). When the laptop is not plugged in however the speakers make the crackling noise before playing sound, and when they finish playing the sounds, the speakers go off ( when I approach my ear the white noise isn't heard anymore).

Notice that the crackling sound is heard only once: after I click on some audio to play; then the crackling disappears, only to appear when I got to the next song ( or audio file).

What do you suggest I do about it? In the beginning I thought it was a hardware problem, but given the fact that during playback the speakers do not exhibit any weird behavior, I am led to believe it is a drivers' problem.

 

Sound Crackles


NGB5, there are several possible causes, so this cure probably won't work for you. But it worked for me.

I had a crackling sound because my speakers were too high. By raising the volume through the Windows software, and lowering the volume by turning the knob on the back of the speaker, I got the same volume without the crackling.

 

Lumia 735 Crackling Speaker Sound

I have just purchased Lumia 735 phone. I am quite happy with it but have been seeing an issue I'd like to see if anyone else had.



It is the case when I have the phone on a speaker, no matter what volume. Mainly I have noticed it with an alarm as I use it the most with speaker. The sound is not always clear and sometimes it resonates. I.e. the sound is crackling, like from a bad speaker.
Anyone else has these issues?
