Issues with audio cutting out in preview

I have not had this happen often before, but recently I was simply playing a video project (VEG file, using an MXF file in 1920x1080 format). The audio cut out for several seconds, came back, cut out again, repeatedly.

I lowered the preview to Draft quality; while the display was affected, I still had the audio dropouts.

I checked that my antivirus program was not doing a full-disk scan -- and it was not.

I'm playing back from a local drive on a very new Dell quad core with 3 GB of RAM.

Suggestions?

Had this happen too along with it getting WAY out of sync.
Hit stop and then play will kick it along. Remove any unused audio FXs. Bypass / remove any non realtime audio FXs like WaveHammer seems to reduce the incidence. Glad to hear even on a fast PC this happens, I thought it was just my old 486 :)

So you upgraded and didn't tell anyone? ;>)

I don't think I (inadvertently) applied any audio effects. Except, I did these 2 things:
- The recording was recorded only on the left channel (using a wireless mic), so I made it two channels/mono by selecting Left Only.
- I Normalized the audio. In Sony training materials, this is recommended procedure.

But as far as other audio effects, I did not apply any.

I just went into Properties and changed audio sampling from 44kHz to 22kHz, and it appears my problem is gone. For voice recording (which is what I'm mostly doing), I'm sure this is fine.

Does it make sense to others that cutting the sampling down like this in Vegas would have the effect of eliminating audio dropouts during editing/playback?

Of course, what's still puzzling is that it seems that it *ought* to be possible to play back with the full 44kHz, too.
