Sudden audio preview playback issue
I’m having a sudden issue in Sony Vegas that didn’t happen last time I used it today.
When I playback my project on the timeline, it cuts out a lot, and sounds as if there is a huge amount of ‘clicks’ when I play it back. The first second or so of playback is fine, but then it starts cutting out really badly. Some of the files are .wav, some are trimmed .mpg’s. Solo’ing a track does not fix it. Rendered .wmv’s also have the same issue. The trimmer plays video+audio fine. The audio files themselves play fine, and if I re-drag the same .wav’s into the timeline from my computer, they play fine. It seems as if the current files in the timeline are corrupt.
Based on a little bit of searching, I believe it could be an audio buffering issue.
My attempts at fixing this involved screwing with : Audio device type, playback buffering (seconds), track buffering (seconds) in the “Audio Devices” tab in properties. I’ve tried changing to draft preview mode. I’ve tried setting the settings to default.
Version : Pro 10
Thank you

You were very close to a possible solution. Disable (uncheck) audio track buffering under audio device

Thanks for the reply. It seemed to fix after I started it again this morning, but I didn’t make any changes. I’ll keep that in mind, though, if I have the problem again. Hopefully it’ll be helpful for someone else with the same problem, though. 🙂 Thanks again.

Certain plugins (like Neat Video because of its resource hogging “no lag mode” especially in a Best(full) preview) can start to mess with the audio outpu on a random basis having to do with the basic happiness of windows at the time. Your problem may reappear. Since I have had Vegas for a while (since before it was video) I still use Waves audio plugins and disabling the audio track buffer kills real time playback completely for some of them and stutters erupt for others. Depending on how much audio processing you have going on (in the future) continuing on without the audio buffer may not always be a viable option.
The one thing that struck me as odd though is that your problem transferred to rendering as well. All the audio stutters and pops I have encountered during playback never appeared in the render. This points to a much bigger problem than just internal resources becoming scarce for certain operations.
