Ordered a new Dell 8400 for a friend, opened it up and found the dvdrom drive with just the power connection and ide connection. No audio cables connected to it. Now, it's been awhile since I got a new system. Is this normal? I haven't started it up since I was just going to inspect for damage and if all is fine, drop it off at his home. Is sound routed through the ide cable or did Dell screw up? If I remember correctly, I have an audio cable from my dvd-rw drive to my sound card. Is one not needed in the Dell?
