    2) Check Background apps

    Check if any apps are running in the background of your PC. Some sound might be coming out of these apps, causing the humming or buzzing sound from your PC.

    3) Check the Timing of The Buzzing

After being connected to the other device, if the speaker still doesn’t sound buzzy or humming, the PC has a problem. To avoid group looping issues, try using a laptop or smartphone that is not connected in.

    Troubleshooting Speaker Buzzing Sound

    Here is complete troubleshooting detail of how you can remove the buzzing sound from your computer speaker;

    Group Loop and AC Line Hums Troubleshooting

    A noticeable change in the group loop can be attributed to the use of a shared ground by two or more devices connected to separate AC outlets. Another issue arises if the connection uses signal cables. The solution to this problem is to use a single AC socket. You can fix these issues by;

    Use a Single AC Outlet

    Using a single AC outlet to power all the linked devices is one of the simplest and most popular ways to close the loop. You can also utilize power strips or surge protectors to eliminate the group loops.

    Use Interactive Line UPS

    One of the best ways to eliminate AC line hums is to use a line interactive UPS. The UPS converts AC to DC if you have an available AC source. DC turns to AC when an AC hum stops, then go through a filter to power your PC.

    Use a Group Isolator

    The easiest answer is to utilize a ground-loop isolator if you don’t have access to a single AC source to connect your gadgets. The audio will have one audio jack through the in-port, and you can plug the out-connector into a PC or other device to use the audio.

    Troubleshooting Radio Frequency and Other Interference

    One of the other significant reasons for the buzzing sound is the interference due to the RF signals. Multiple electronic devices in our home generate electromagnetic signals; they might be responsible for inducing sound to your speaker. If you cannot keep a sufficient distance between the interfering gadgets and your audio devices, keep your PC, speakers, and other audio equipment away from them. To fix this issue, you must update the audio driver. In that case, you can use proper shielded cables that will protect your device from interfering RF waves that might be a source for broadcasting stations or radio towers.

    There is also a possibility that your PC’s internal components are producing interference when you connect the speaker to the motherboard. EMI might have an issue due to components such as graphics cards. The best solution for this problem is to use headphones or DAC to get rid of this problem.

    Troubleshooting Amplifier/Speaker Problem

    There is a possibility that your speaker or amplifier is old, damaged, or low quality. In this case, you will have to replace the speaker. You might try cleaning your speakers and removing any dust causing the buzzing noise. To stop the cones from buzzing, you will need to remove them and clean them. Clean the woofer outer membrane, speaker, cone rubber, and tweeter dome membrane to fix the issue.

    Troubleshooting Software Issues and Updating Audio Driver

    There are many complaints about speakers buzzing when the computer is off. It might be due to some software seasons, such as an audio driver. You need to update the audio driver to remove this problem. To update your audio driver, you can update it by searching in the drivers and reinstalling them with an update. You can also disable the audio effects to remove the buzzing and humming sound.

    Why Is My Computer Speaker Static?

    Your computer speaker becomes static because of outdated and corrupted audio drivers; they can cause disruptions. You will have to update the audio drivers to remove any corrupted drivers.

    Why Do My Speakers Buzz When I Turn Them On?

    There are two leading causes of this problem. There might be a lousy audio cable connected to the amplifier causing it to buzz, or electrical noise passed through the amplifier cable causing this buzzing when I turn it on.
