Hey there isdabest,
Thanks for reaching out for assistance.
I will gladly assist you with your concerns on a buzzing sound while listening to music. There could be a few things that could be causing this to occur like an external device where the audio is being redirected, or it's also possible software problem or physical damage is causing the issue.
Remove any external devices:
1. Remove anything plugged into the headphone jack, including selfie sticks, charms, etc.
2. Remove any third-party cases, protective films, skins, adhesives, or any other accessory that usually comes in contact with your phone.
3. Disable Bluetooth by swiping down from the top of the screen to open Quick Settings. Tap the Bluetooth icon to turn off Bluetooth.
Dry your phone if it has gotten wet:
Audio problems can occur if there is water in the speaker.
If your device has gotten wet, dry it off right away and try to remove as much water as possible. Be sure to pat the earpiece (at the top front of the phone), the primary microphone (at the bottom of the phone), external speaker (also at the bottom of the phone), and the USB port with a clean, soft cloth.
Do not expose the phone to salt water or ionized water. If your phone is exposed to salt water, wash the phone with fresh water, and then dry it thoroughly with a clean, soft cloth. Otherwise, when it dries, salt may accumulate and block the primary microphone, earpiece, or external speaker.
Test the speaker:
Use the Volume keys while playing music to ensure the sound is not muted. If the sound quality is fine, then your speaker is working normally, and one of the external devices you removed was causing the problem.
If the symptoms still persist, I would recommend making sure your device is up-to-date to the latest software.
Next, let's boot the device in Safe Mode. This mode disables all third-party apps from running in the background.
Follow these steps below:
1. First, completely power off the phone.
2. Power on the device and when the Samsung logo appears, press and hold the Volume down key.
3. If done correctly, "Safe mode" will display in the bottom left corner of the screen. If "Safe mode" does not appear, repeat the steps above.
4. Once you're in Safe mode, you can remove the third-party app that is causing issues.
5. To exit Safe mode, simply restart your phone or tablet, and it will reboot normally.
Use the phone or tablet normally to see if the issue has been resolved. If the phone is operating normally, a recently installed app was most likely causing the issue.
If the issue is gone in Safe mode: One of your recently downloaded apps was likely the cause of the problem. I would recommend deleting each of your most recent apps until you are not experiencing the symptoms anymore.
If the issue still exists: Downloaded apps may not be the cause of the problem. You may need to reset the phone to the factory setting. I know this may not be the ideal step to take, but this will set the phone to its factory settings. Make sure you fully back up the device to ensure you don't lose any important data.
After you perform a factory reset and restore your device and still experiencing the buzzing sound while playing music, a service repair is recommended on your device.
