Speakers making Humming and Buzzing Sounds (Hiss and Hum) noise. Realtek on board Audio card not working properly. Solution

If you are having problem with audio on your computer, then it is not necessary that your speakers are not working properly; the problem could be in your Sound card. Yes, like a video card is needed to show visual contents a Sound card is also needed to play audio. You may not found a sound card on your motherboard because all the new motherboards (which supports Intel Pentium 4 processors and above) are having integrated sound cards. But this integrated sound card can also be get damaged even if everything else is working just fine.

Some of the Symptoms of sound card problems are-

1. Speakers making “Hiss and Hum” (Humming and buzzing) noise.


2. Audio skipping in between.

3. Audio not working properly (being cut in between) at higher volume.

4. There is “device unplugged” and “device plugged” notification pop repeatedly.

(These are not ALL the symptoms, you may be having some other trouble with audio and problem could be the same (sound card problem).

Solutions-

Okay, so we will begin from trying out basic solutions moving to the extreme one.

1. Check all the cables connecting your speakers and computer. The jack (mostly 3.5 mm jack) should be fitted in properly. Try twisting the jack while fitted in computer and it should not get twisted easily.

2. Connect different speakers (with low power). If the new one is working properly then it could be that your old one is not compatible.

3. Disable the front panel jack detection.


To do so-

1. Open “control Panel” from windows “Start” menu.

2. Open Hardware and sound.


3. Open “Realtek HD Audio Manager”
                                               

4. Open “connector settings” (The folder icon on the top-right corner)

5. Check “Disable Front panel jack detection” and click OK

4. Disable the front jack.

How to disable and enable Front Panel Audio jack.
For this open BIOS by pressing “F2 key” when the option appears. You can use left and right, up and down arrow key to navigate. Enter to select, Esc to go back. Now go to Advanced, then Peripheral configuration, you will see “High Definition Front Panel Audio” navigate down to it and press enter and select “Disable”. Press “F10 key” and select yes to save the changes and exit


5. The problem could be in software. Re-install or update your Sound card drivers. You can find them in the drivers CD you get with your motherboard. Or if you have lost it you can download them from internet. Just search the word “drivers” with the model number of you motherboard. For example if your Intel motherboard model is- DG41WV. Then search on Google- Intel DG41WV drivers. You will get official link of Intel website for the drivers. (Download only from official website). No need to download the complete board drivers. You can specifically download the Audio drivers.
Clean procedure to reinstall drivers.
1. Disable your Audio from BIOS. Steps are same as mentioned in method 3. This time just disable Audio.

2. Now uninstall Realtek Audio drivers from control panel.

3. Enable Audio again from BIOS.

4. Install the drivers.

6. If the above methods didn't work, check your SMPS PSU (Switched Mode power supply unit). If you are having an old SMPS then it could be the problem like in my case. Replace your SMPS with some other working SMPS from other computer and check if the audio is working properly. Sometimes SMPS gets old and do not supply power properly. If you have recently added a new component (example- a graphics card) which requires high power then insufficient power may be supplied to sound card and leads to improper functioning.

If none of the above solution worked then it can be that your on board Sound card has been damaged and will never work again. It is possible that only on board sound card get damaged and rest of the computer work perfectly. One of the reasons of sound card getting damaged is fluctuation voltage. So, if you have confirmed that your Sound card is damaged permanently, then do not worry you can install an internal PCI sound card. A good sound card will only cost $5 to $10 not more than that.

  1. Remote speakers work pretty much the same route as standard radios. At the point when the beneficiary plays the music, a gadget inside the speakers gets signals. These are then changed over to advanced signs and afterward transmitted to the speakers. read the article
