Actually same issue for me - as a bonus for installing CS3! Never ocurred under 1,5 - 2 (Integrated sound chip + when needed digidesign m-box) but it should be mentioned that I then worked almost only with SD.
I have just started to look into this but -issue still not resolved. My speculations goes in direction of ram-shortage ( 2gb) when the hdv projects exceeds some undefined limits ??
Let us know if You come to a solution.
I get the exact same problem only when previewing in High Quality. Drop it down to Draft and the problem will go away. (Weird)
This seems to be a bit of a bug.
Premiere 2.0 never did this.
There is a change is CS3 that allows audio playback in nested sequences without rendering the audio first. Perhaps this change has affected playback elsewhere?
Might be worth a bug report - have any of you filed?
Noy yet, maybe more people should try confirm it...?
If your "built-in" audio chip is a Realtek HD audio, you may be having problems due to that. Run a few google searches for your audio chip and you may find the same problem is widely experienced. That was my problem, and after hours of jacking around with drivers and patches, I broke down and just bought a $29 soundblaster PCI Audig card and all stuttering ceased in all applications, including native HDV.
I don't use the "built-in" audio chip mystroh. I just used it to test the problem to see if it is hardware or software. Since all three hardware devices I tried, demonstrated the problem, I was assuming it was a software issue.
I can't duplicate it "on demand" and I've only seen it happen twice. I'll try Howard's work around next time it happens.
Howards "draft mode" solution helps a bit but not completely.
(I'll buy a separate sound card)
I can confirm that I have this issue with CS3. I have a seperate sound card (Creative SB XFi).
Switching to draft mode doesn't help much either.
The problem starts when one does some editing (but I thought PPro was an editing application). I have to shut down PPro and re-start it to get rid of the problem. After this happens a few more times and eventually just re-boot.
The first time this happened, I was thrown for a loop (I'm new to PPro) and spent a good hour trying to figure out what I migt have done to screw things up.
By the way Just so I know, how many people does it take to confirm a problem?
I have an on board sound card and the problem exists only when editing native HDV.
I always use my Creative Audigy 2 ZS Platinum Pro and the problem persists. With the same project in Premiere 2.0 I never experienced this problem.
EDIT. Hmmm Creative pops up a lot here, perhaps it is a conflict between Creative and Premiere?
If more people who
b don't own a Creative card
can reproduce this, then we must post a bug report.
I *don't* have this problem and I use an M-Audio card.
EDIT: Never mind, I also don't edit HDV.
Has anyone noticed a pattern as to what "triggers" this problem to start manifesting itself? It seems to just start happening for no apparent reason.
Howard, now that you mention it, I've only seen it happen with native HDV as well and I've logged a lot of hours with different formats.
It happens whether I start the session using firewire hardware (the Digi002), a PCI-X card (the Xena) or the built-in sound chip. I can even switch between the audio hardware once it happens and still have the problem. Oh yeah, I'm at least one person who doesn't have a Creative card.
I do have an M-Audio card that I could put in the machine and try if I thought it would help w/ the troubleshooting.
I found it happened only when on High Quality and when I increased the amount of video & audio layers.
Yes it only happens with native HDV.
From what I see, it happens the moment you start moving clips around. Either shifting them or drag dropping them.
Currently my project (HDV) has 7 video layers and two audio layers, however, even when my project had just two video layer and an audio it would happen.
I don't know what native HDV is. I'm capturing my footage using firewire and PPro CS3.
Shiv, the reference to native HDV means, the file you capture as a "native HDV transport stream" from an HDV camera through the firewire. This sounds like what you are doing.
Some people capture their HDV into an intermediate codec like Cineform and edit that. In that case you aren't really editing HDV.
Thank you for the clarification/explanation.
I have found that when your computer system is maxed processing your HD footage, it drops the audio on playback. if you hit "ctrl" "alt" and "delete" one time together, it brings up the Windows Task Manager window. Simply select the "performance" tab or watch the icon down by your clock as you do your HD playback and see if it happens to you as well.
Premiere Pro has behaved like that for several versions now, all the way back to when DV was king. If your CPU is maxed out playing video, then there's no processing power left for the audio.
PPro defaults to dropping the audio during playback if it means it can keep the video going.
This evening I was doing som minor, but repetitive, rendering of a HDV project. ( 10 sec's clip part of a 5 min proj). ppro3 *the only running program *,no bacground tasking. Then suddenly " Premiere is running low on system memory - please save and exit".
Naturally I bended and did what I was told to - no damage done.
But ..... wonder if this could lead us in some particular direction with respect to the origin of the sound troubles recently described here and in other postings
(2 gb ram , good standing machine elsewhere)
Has anyone solved this problem? I saw that one person bought a Sound Blaster card for $29 that seemed to solve his problem but other people are reporting that external sound cards don't help them.
I still have it even with the 3.1 update. I still can't figure out what "triggers" it. Shutting down PPro and starting it again is the only way I can get it to stop.
Since it seems that the audio driver has been ruled out as the culprit, I'm thinking it might have to do with hard drive performance.
Where do you folks typically keep your conformed audio? (This is under preferences - scratch disks - Audio Previews) Usually, by default, this is set to 'same as project'.
Here's one theory: if this happens to be your c: drive, there's a good chance that your Windows swap file is on the same drive. What might be the trigger for the dropouts is that Windows starts using the swap file in order to acquire more memory, and the extra drive seeking is enough to cause the audio being played back from the same location to jag.
So, I'd check if moving the conformed audio path to a dedicated drive helps (I also strongly advocate that your Windows swap file should always be on a partition separate from your media as general good practice).
See my remark to your duplicate post on the other thread.
Oh yeah, I commented on that duplicate thread too...
