(4 points)
The first sentence "Alberto oyó la música de la fiesta y salió de casa" means that Alberto heard the music of the party and then left the house. It implies that hearing the music was the trigger for him leaving.
The second sentence "Alberto oía la música de la fiesta cuando salió de casa" means that Alberto was hearing the music of the party when he left the house. It implies that he was already hearing the music before he left, and it doesn't necessarily mean that hearing the music was the reason for him leaving.
