Depends where you're asking

Sound is pressure waves in the air. So when you pluck a guitar string, you can see it wobbling back and forth - that's moving the air around it back and forth, which makes pressure waves, which your ear detects and your brain turns into the note that you hear.

If there's no air, there's no pressure waves, so no sound. So if you're in space, which is an almost total vacuum, and you pluck a guitar string, there's no air for the string to move, so there would be no sound.

Similarly the Sun is a very violent place - but stand off it and you will "hear" nothing because there's no air to vibrate.

Inside the Sun is a different matter altogether. There is a lot of gas and a lot of plasma which moves around very violently. If you're entirely impervious to the heat and pressure you will hear quite a lot of noise.

The Sun is actually quite fascinating to the nerdally encumbered. It's not all that dense, it takes a looooooong time to cook hydrogen into helium. It takes tens of thousands of years (at least) for a photon to get from the core to the surface of the Sun, but only eight minutes to get from the Sun to the Earth (ok I'm handwaving a bit there but in essence, that's completely true).
