No, sound transmitted through a laser beam and sound transmitted through an electromagnetic wave do not travel at the same speed.
In general, sound travels through a medium, such as air or water, as a mechanical wave. Its speed depends on the properties of the medium it is propagating through. In air at room temperature, for example, sound travels at approximately 343 meters per second (or about 1,125 feet per second).
On the other hand, electromagnetic waves, including laser beams, travel at the speed of light in a vacuum, which is approximately 299,792,458 meters per second (or about 186,282 miles per second). The speed of light in a medium, such as air or glass, is slightly slower than its speed in a vacuum, but still significantly faster than the speed of sound.
Therefore, the speed of sound transmitted through a laser beam would be limited by the speed of sound in the medium in which the laser beam is propagating, whereas the speed of electromagnetic waves, including laser beams, would be limited by the speed of light in that medium.
