These days my desktop speakers are making some strange kind sound which is very disturbing and annoying. I have checked the jack and plugs and found accordingly. I just can't trace out the problem. Please help.
Which kind of sounds? Are they high frequency noise signals or low frequency (like bass) etc.?
If you can tell in detail the sounds, then it might be helpful to diagnose the problem.
Have you checked for any background program that might be running that is creating the noisy sounds. Check your speakers on another PC for confirmation of that. If noise is there too, it means there is problem in the hardware of the speakers and that will have to be looked at by some hardware expert. Do check the cables for any breakages too.
If the sound coming from your speakers connected to your computer is odd and annoying, the problem is probably not with the speakers but with the sound card installed on your computer. To properly check the cause of the problem, you need to check first if the speakers are working properly.
Disconnect the speakers from your computer then connect it to a different device like your Smartphone, maybe, if it supports 3.5-millimeter jack. Once it is connected to your phone, play some music to see how the sound goes and raise the volume as loud as possible. If the sound seems to be fine then you need to replace your sound card.
If your sound card is built-in and it is starting to create odd sounds, it can cause problems to your computer. The most common problem I’ve encountered with a faulty built-in sound card is sudden restarting and several system crashes. One temporary workaround if you don’t want to disable the sound card from the BIOS is to lower down its acceleration level.
Lowering this setting will reduce the risk of triggering a system crash which causes the computer to suddenly restart because you are not using the device at full capacity. This setting can be adjusted using the Microsoft DirectX Diagnostic Tool or the “dxdiag”. To adjust the setting, click “Start”, “All Programs”, “Accessories”, and then “Command Prompt”. In the command prompt window, type without quotes “dxdiag” then hit Enter.
In DirectX Diagnostic Tool window, select “Sound” tab. Under “DirectX Features”, in “Hardware Sound Acceleration Level”, move the slider one level to the left to reduce the acceleration level of the sound card.
After this, play a music on your computer to see how the sound goes. If you still hear some disturbing sound, adjust the acceleration level again one level to the left. Once you are comfortable with how the sound goes, click “Exit” in DirectX Diagnostic Tool. You need to keep the acceleration level at this level until you replace your sound card.
