Noise coming from speakers - Please read.

[Jubair BD]

I built the PC in September 2022. Recently when I work on Photoshop and CPU usage is a bit high, suddenly there is a very loud analog CRT tv noise type of noise that comes out for around 10-15 seconds. Then I immediately need to mute all the background music volumes to stop the noise. After 10-15 seconds, this gets fixed. I want to know what is the probable cause of this issue. Please note I only notice this when there is something playing in the background. If there is nothing playing, then there is no noise for that 10-15 seconds period. I also noticed that the noise is proportional to the volume level. If the sound volume is set to high then the noise is higher. If the sound volume is at 0 then no noise is coming. But if I play something in that 10-15 seconds period then I can hear the loud noise again. It is now happening every day and it is super annoying.

You can start troubleshooting by disabling your monitors speakers in windows.  If the sound stops, one or more installed programs are causing the noise.  If it happens with the speakers disabled in windows, try cranking you volume to 0 in the monitor UI.  If this fixes it, there is likely some short in the monitor causing the issue.

 

Finally if you have the speakers disabled in windows, turned down to 0, and you are still getting noise it is electrical interference.  You might try removing the monitor from the UPS or adding it to it.

 

Just I have had a monitor next to a microwave, and on the same circuit do the same thing.  Even when we plugged the monitor into another circuit, same issue because the RF interference kicked up by the microwave oven.

Thank you very much for your response. My monitor does not have sound. I have an external 2.1 speaker. I have made sure the speaker is okay. It may cause by RF interference. But I noticed it only happens when there is a spike in the CPU usage, or high CPU usage when I am using Photoshop.

If its an external speaker, they can actually pick up RF worse than a monitor....because most of them are not RF shielded.  For a test move them away from your computer, like across the room or unplug them and see if the noise stops.  Next if moving the speakers away from your computer is not an option, stupid stuff like building a simple fairiday cage around a speaker have fixed them in the past.

 

Also the interference may be coming from your AMP or whatever the speakers are plugged into.  If they are plugged into your PC, make sure the wires are all the way plugged in (loose wires can hit a computer case and make noise).

 

And in the end you may want to get shielded speakers and a shielded amp as well, even if you are going to plug into the PC.  Just wifi and bluetooth and even your power supply can kick up enough RF to make an unshielded speaker sound off.
