I've tried to open different videos and audio files but I can hear no sound at all, what must I do?

Just a guess, but start by looking at this setup window to make sure that you have Premiere Pro pointing to the correct audio device.
I am having the same problem I have windows 64 bit, windows 8, premiere cs6. I have done the updates, I only have 1 item in the audio device. The audio is saved as a mp3.
