No audio preview with video

New to Vegas Movie Studio 4. My problem is when I drag the .avi files into the timeline I cannot hear the audio when I play them in preview mode. I know my soundcard is working and the .avi's are ok because they work in other DVD editing programs and windows media player etc. Also I have checked that the mute button is not depressed. I am really frustrated. Any one know what is going on?

Do you see the audio waveforms on the timeline, or are audio events a straight line?

What soundcard do you have? What are the settings in the audio preferences? Make sure the audio fader isn't set to a very low volume.

Do other files (WAV, WMV, WMA, MP3, etc.) play just fine? If so then it is probably an audio codec issue. You can check the audio codec by looking at File | Properties when you play it in the Windows Media Player.

thanks for the response

ah when I play a WMVfile I see it adds voice as its own track and I can here it when I press play. With my AVI file it does not add the voice track hence no sound, but the strange thing is in other DVD authoring software and in windows media player I get audio just fine. Does this mean I a missing a codec specifically for Vegas?

According to Windows Media Player the video codec I am using is: DV Video Decoder. The audio codec is: WMplug

Sound Card -- I have a SoundBlaster Audigy 2

Just to make sure we're clear on the issue -- where do you your files originate from?

If they're files you've captured from a camcorder, is the cam DV, analogue or DVD?

The files are from my DV camcorder using miniDV tapes.

I believe I originally imported the video using Windows Movie Maker (at least I think I did). Unfortunately I cannot capture the video again since I have erased the tape.

Just as an experiment, download a freeware program called Virtual Dub.

Open your AVI in Virtual Dub. Assuming it plays just fine (which it very likely will), choose Save As and save over your file.

Any time I've had a compatibility issue with an AVI, Virtual Dub has automatically transformed it into something I could use.

I'd recommend saving to a new file, just in case something goes wrong. Disk space is cheap these days. Since you've already erased your tape, you won't be able to recapture.

I downloaded Virtual Dub and tried to open the file and it gives me an error. It says "Virtual Dub requires Video for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Play are not suitable."

Ahh this is frustrating.

But at least there's a way forward. Get hold of GSpot and see what codec you need to deal with your avis. I haven't used GSpot in a while, but I think it will tell you where to find the codecs as well as identifying what's missing.
