buzzing sound

I’m hearing a light buzzing sound in my earphones that only happens when any audio is playing. When there’s no sound, everything is completely silent.

The buzzing is coming from my earbuds/headphones. I tried multiple headphones and the same issue happens with all of them. For the first 2 years after buying my PC, there was no buzzing at all — it only started recently.

It began after I installed Nvidia Broadcast. I already uninstalled it, but the buzzing sound is still there.

My PC specs:

• RTX 4070
• i5 14400F
• 16GB RAM
• Bluetooth dongle
• Wireless mouse dongle

Has anyone faced this issue or knows what might be causing it?
