Odd blasts of noise in Vegas 12

Doug_Marshall wrote on 12/5/2013, 10:03 PM
I'm recently having an odd problem. In a project with audio files only, the sfk files that Vegas builds show nothing related to the actual material. Everything displayed is just intermittent blasts of noise. Vegas plays those blasts also along with an occasional blip from the actual sound of the file.

The sfk display files also display as blasts in Sound Forge but the audio does play correctly. If I delete the corrupted sfk files, Sound Forge rebuilds them properly. However, the problem in Vegas still persists.

Any ideas?

That is most unusual; I suspect some disk problem; reason is another DAW I've used for 20 years exhibits exact same symptoms when the hard drive is going bad.

Interesting. I'll copy the drive and see if the replacement does any better. Do you think the fact that the drive is connected via USB (2.0) could have any bearing? It's a 4 terabyte drive, btw.

The thing that has me most confused is that Sound Forge has no problem at all playing the files even though the corrupt sfk files display garbage patterns (until they are deleted and SF rebuilds them).

I copied the files in question from the external drive to one of my overcrowded internal drives and, from there, the files play just fine. From that I can't determine, however, whether the fault was with the disk or its USB (2.0) interface. In any case, the files did play fine from that disk in Sound Forge, just not in Vegas. Hmmm...

Therefore have to assume there's some difference between the SF and Vegas audio streaming playback engines - only SCS will know the answer to that; did you start a support ticket?
Unless you have some radical difference in the Audio Buffer size in both apps????

Hey, sorry I missed your response. Yes, I recently started a support ticket. Response takes a while, as you know...

I hadn't ever messed with the buffers, that is, until I had this problem. In any event, changing the settings didn't change the results at all.

I've been importing some older projects to this drive for backup purposes and have noticed that these older projects seem to play somewhat better (Vegas files as old as 2001): there is one short blast of noise upon starting followed by good playback.

Update: Tech support asked me to copy one of the problem projects from my 4 tb drive to a smaller one and play it. I did so, it played fine. They informed me that this is a known issue that will be addressed in a future update.
