Sound only plays from beginning of track

Steve672 wrote on 4/5/2003, 11:35 AM

I must be missing something simple but I am unable to play sound on a particular track unless I put the curser to just before where the sound was added and then it plays. If I try starting it in the middle of the song all I get is silence, the video seems to play with the original sound track but not with the sound I just added on another track.

BTW I have 2 sound tracks, the original with the video and a second one that has my added effects. It's the second one that does not seem to play unles I start at its beginning.

Almost sounds like a buffer problem to me. However I don't know enough about those things to really tell for sure.

What kind of sound card do you have and are you using the newest drivers?

Thanks JBJones. I am using a USB external sound card, SB Extigy. Interestingly enough the sound plays OK if the cursor is placed in the beginning of the clip but not in the middle so I am not sure if that's a buffer problem. Any other thoughts?

F.Y.I. I have an Extigy also and it works ok on both VV3 and V4.

I have increased the buffer but still no luck. Is there a setting that I am overlooking?

When I said it "Almost" sounds like a buffer problem I didn't really expect that changing the buffer size would help. Maybe the buffer isn't loading the sound clip for some reason. Seems like this might actually be a complicated problem.

Can you post the rest of your system specs?

Motherboard
Processor
O.S.

Is the Extigy plugged into an add on USB card or the standard MoBo ports? Anything else advanced plugged into the same USB's?

You know, whatever might be along the path between Vegas and the speakers.

I'm thinking it's a source media problem and not an output problem. Perhaps it's not "seeking" properly when played from the middle, but starting from the beginning works fine. I've never seen that, but I imagine it's possible. What format is the source audio, MP3, WMA, or some other compressed stream? Try rendering the sound to WAV and using that in your project; does it work right then? We might want a sample of the file if that's possible for testing. Also, try the 4.0b update (should be up Monday) to see if it works better, as there were audio engine improvements.

Got it to work!!!!
Thanks for all your help. I took Dennis's suggestion and converted the culprit MP3 file to a WAV file and seems to work as it should. (I also went from a 3.3K file to a 35K file). It seem that Vegas "couldn't see" the MP3 file when started part way through.

For those of you who had it working it would be interesting to find out what file format you had. At any rate I will update to 4.0b on Monday and report back to see if it made any difference when I will try again with the same MP3 file.

BTW I am running: Win XP PRO
ASUS P4B533 MB
dedicated 80 Gig HD for Video only
ATI 9700 PRO video card
1 Gig RAM
P4 2.4Gig CPU
SB Extigy USB sound card connected directly to m board and not a separate USB card (it is the only USB connected to that port - no hub)

Installed 4.0b and still no luck with the MP3.

Has anyone tried this with an MP3 file??? The WAV files works like it should.
