I take it, that when you say 'playingback the movie', you mean within FC.

Open one of the DV files in QuickTime player and do a Command-I on it to see the audio settings. Does it play back with audio in QuickTime Player? If I recall right, the audio codec should say "DV, Stereo, 48.000 kHz". I don't have a native dv file handy and had to create on to see that.

when you play the movie in QT, does it show a separate video AND audio file? For Final Cut to use the sound, the video needs to be demuxed (audio separated from the video)

Here are the details from one of my DV files as downloaded from the camera. I'm using NTSC.
DV, 720 x 480 (640 x 480), Millions
16-bit Integer (Big Endian), Stereo, 48.000 kHz
I think you have to convert your audio portion to be 48kHz.

If when you scrub through your material in FC you can hear audio, but you get a beeping sound when simply playing back, then I'm pretty sure this is the issue. There would be a red bar on the top of the timeline for affected clips when something needs rendering, which can include audio.

xstep is right - unless you match your comp to the DV settings of your movie, then it'll have a grey bar on the top of the track, so you can scrub freely. It's best to create a new comp with the movie's settings then trying to fix an existing one after the fact.
