My problem took a bit more effort to uncover than a basic restart, so if you want to know exactly how to try the above solutions or what else could be causing the problem, keep reading. First, restart your computer if that doesn’t fix the problem, try updating your settings, audio drivers, or changing your default sound device, among other solutions.
It could be your computer setting, a recent update, or a driver update. So, why are the speakers still playing when you plug in your headphones? What the heck?! Obviously, I went into problem-solver mode, and it seems this is quite a common issue. A strange thing happened to me the other day, I plugged in my headphones, and the sound continued to stream from my speakers.
