I was just thinking: I have heard clicks and pops when previewing a project in DVDA, BUT, when I play the DVD in regular set top or software player the audio is perfect. Are you talking about what you hear inside DVDA or normal post-burn playback? I believe the former is a known issue (someone correct me if I'm wrong).

JAB: Are you sure these pops are actually in the file? Can you see the pops in the waveform?

Can not see them in the waveform but playing repeatedly over the affected area produces the pops at the same spot. However, re-rendering will produce pops in different spots. Can't see them, but can hear them.

Hi JAB,
I went back to 4.0.
Hi Sonic EPM,
My symptoms were exactly like JABs' ("Can not see them in the waveform but playing repeatedly over the affected area produces the pops at the same spot. However, re-rendering will produce pops in different spots. Can't see them, but can hear them.") so I would think that eliminates the sound card (since the rendering process doesn't go through the sound card).
BTW, thanks for your concern Sonic EPM.

I re-rendered a 5 minute section without the reverb automation envelope and it is pop free. I really need that to work in this project. It is a musical with lots of narration. It needs the reverb during the music, but doesn't during the narration. Like I said earlier, I can ship the finished audio out the spdif spicket of the Audigy card to a DAT machine and turn it around and recapture. I really don't want to go back to 4.0 either. I have a shuttle pro and 4.b fixes scrubbing in the trimmer.

Randy:
Did your files have a lot of FX?

Thanks,
JAB

If you burn the files to CD, and play in a dedicated CD player, are the pops still present? (I want remove the soundcard completely from the test scenario...)

>>>Randy:

It was a 2 camera shoot and I had to do color correction on one track, but other than that just transitions. Audio track had nothing but normalization.

Ahhh...normalization. I too had normalize on. I removed all the effects and normalization and got a clean render. I will try to repro the problem this evening adding back the effects and normalization.

SonicEPM:
I have not tried to burn to a cd but will tonight to rule out the sound card.

Sonic EPM:

I did not burn the track to a cd, but did take the .wav file via network to another computer and the pops are embedded in the file. I ended up exporting the timeline to DAT via spdif and re-recording a .wav from the DAT via spdif and it plays fine. I will be rendering to mpeg2 for DVD tonight so it will be interesting to see what happens then. I suspect that it will be fine. After I get this project out the door, I will do some extensive trouble shooting to try to pinpoint the exact fx, or parameter change that is causing the problem. I sent Nick some files yesterday, .veg and a sample .wav with the pops in it. Let me know if you guys come up with anything.

Thanks,
JAB

FWIW, yesterday I uninstalled my other SoFo products (as some suggested) and then reinstalled 4b. Immediately the pops in renders were back even after burning DVD (in DVDA). I'm not bitching, 4.0 is working fine for me, but just thought Sonic EPM might want to know.

Was this issue ever resolved? I am having the same problem now. I have used Vegas 4.0 for a couple of months but Vegas user for over 2 years. Only new setup is I upgraded to new computer,(Boxx system) but I have completed other projects on this system prior to this problem. I am now having the audio pops. It plays fine within the timeline of Vegas but when it is rendered the audio is messed up.

Thanks,
