I have just bought a new computer, i want to play fsx. But it has no sound. I played it on an other computer and on that computer was sound for fsx.I only hear something in the cockpit views, but no voices in atc or missions. What do i need to do?

Does your new computer have speakers?Is the volume on in the audio manager?Are all the FS sound settings on?

Have you chosen right sound card in FSX setup, if you have both on-board and additional sound card?
