This is really embarassing. I've used other basic video editing programs for awhile now...so you'd think I wouldn't have a problem w/Vegas.
I load up a piece of captured DV that I KNOW has audio b/c I've already worked with it before. When I click "play" it plays in the preview window at the bottom-right, but there's no sound. None of the "mute" buttons are pressed. What gives?
Thanks!

*EDIT 5 APR 07* THE FOLLOWING EDIT IS REALLY LENGTHY. IF YOU WANT DETAILS (and I think you should!) PLEASE READ IT ALL. If someone could explain the TECHNICAL reason behind this, I'd really appreciate it. As I explained below, I wasn't getting any audio in known-good DV video clips. I emailed Sony. I must admit; they replied within TWO HOURS. That is exceptional customer service speed, to say the least. However, the quality/knowledge base that I connected with left much to be desired. THE BOTTOM LINE IS THAT VEGAS MOVIE STUDIO WON'T FULLY (i.e. with sound) PLAY BACK ANY VIDEO YOU CAPTURED TO .AVI WITH SOME OTHER PROGRAM. YOU MUST RECAPTURE IT WITH VEGAS!
For those that want all the details; here's a cut and paste with no edits (save for my and the guy's name) of the email traffic that transpired b/t myself and Sony. I'm very disappointed and pretty much pissed off. I've been working on this problem for three days now. I think I provided MORE than enough detail in order that my problem be accurate assesed. The technician obviously didn't thoroughly read my original question...I wound up with a "Tier 1" type reply.

I'm so glad I figured it out...MYSELF...but I'd still like to know WHY it is this way.

I have no sound when previewing a clip (raw DV). I have not changed anything in Vegas; I loaded the program and began trying to use it. I Import a DV clip. I hit play. It plays (video) in the preview window, but I have no sound.
My computer works just fine. I have sound in every other program. Games, playing CDs/MP3s. When I play the video clips in Windows Media Player, Windows Movie Maker or Nero Vision I have sound. Just no sound in Vegas. It's driving me nuts. I've checked everything and nothing is muted. PLEASE help. I want to start learning the program, but this is a major stumbling block.
Greetings Michael!
Thank you for contacting Sony Media Software Support.
How are you connecting from camera to the computer? Vegas cannot capture through a USB connection. You would have to connect the camera to the computer via Firewire, which is sometimes called iLink or "DV".
If the information provided does not completely answer your question, please update your incident so I may further assist you.
Have a great day.
Customer 04/05/2007 02:16 PM I have not tried capturing any video from a DV camera yet. This is with DV clips that are already saved on my hard drive. As I stated earlier, ALL the clips play just fine in every other application except Vegas. The video plays, but there is no sound.
Greetings Michael!
Thank you for replying.
Most still image digital cameras that can capture short clips of video use a Motion JPEG (Joint Pictures Experts Group) codec for file compression. A directshow Motion JPEG codec must be installed on your PC in order for these clips to be imported into a Sony Media Software timeline. The following manufacturers produce Motion JPEG codecs:

I hope this information is helpful. If you have followed up questions or need further assistance with this issue, please update this incident.
Have a great day.
Thanks for the replies. The video clips I am trying to play were not captured with a digital still camera. They were captured to DV Tape on a Canon Elura 100 Mini DV cam.
The video was transferred via Firewire to my hard drive in Windows Movie Maker. It is .avi raw DV video.
Why do I have no sound in Vegas, but sound in every other application when I play the clips?

If this doesn't fix the issue you are facing then please attach a small portion of the file about 15-20 seconds and update this incident with the information so that we may further assist you with this issue.
Customer04/05/2007 04:27 PM I figured it out myself; you would be well-advised to add this fix to your list of "Solutions to problems."
I don't know what the technical reason is, but the solution was to RECAPTURE the video using Vegas. I used a small (30-minute) clip as a test and it worked fine.
This is a FLAW in the Sony Vegas program!!! Raw DV is raw DV. It doesn't matter what program you use to capture it with! Just like an MP3 is an MP3. The 100GB of video I previously captured using Windows Movie Maker and Nero Vision should be able to be used in Vegas; they were captured as .avi files; ordinary DV video. It has NOTHING to do with some JPEG codec like you linked me to in two of your replies.
JPEG? That would be a STILL PHOTO file format, not a full motion with sound video format.
Why should I have to pay extra OR go through any extra steps in order to play back ordinary .avi video on Vegas? I paid good money for the Vegas software; it should play back any type of video without any problems.
I really wish I knew the technical explanation as to why video files saved to .avi with other programs won't play back in Vegas.
In summary: The answer to my question (though without a technical explanation) is to RECAPTURE WHATEVER VIDEO YOU WISH TO WORK WITH USING SONY VEGAS. Then it will work fine, Video & Audio together.
