No, sound would not travel faster than light even if there was no air.
Sound is a mechanical wave that requires a medium, such as air, water, or solids, to propagate. In a given medium, sound travels at a certain speed, which depends on the properties of the medium. For example, in air at room temperature, sound travels at approximately 343 meters per second (about 767 miles per hour).
However, in a vacuum where there is no medium to transmit the sound waves, there would be no sound propagation. Since light can travel through a vacuum, it would still be able to propagate and travel at its constant speed, approximately 299,792,458 meters per second (or about 186,282 miles per second).
In summary, without a medium to transmit sound waves, there would be no sound propagation, while light would still be able to propagate through a vacuum at its constant speed.
