sound drops out of certain clips intermittently but can still see wave

This is driving me crazy. I've searched and searched to no avail.

For some reason certain segments have no audio intermittantly. What I mean by that is usually one entire clip (say section2.mpg) will stop producing audio for any of the segments on the timeline that come from that clip. THe waveform is there and it seems that it should be fine. Since I assumed this might be a memory issue etc I tried rendering and still same thing. No audio in certain areas. So I took the file and imported it again with a different name and replaced the section2.mpg with a new one called section2b.mpg and it worked again. BUT then it stopped working again even with the new clip. AND then it worked again if I removed from the timeline and replaced and sometimes that works but sometimes it doesnt.... ahhhhhhh HELP!!!! 

I'm using Vegas 10 and I have used it on two different computers with the same exact problem. I even have used brand new installation files downloaded from Vegas on the brand new computer. Intel Core i7-6700k 4ghz - 24 gig memory. Both machines run windows 10 and are 64 bit.The clips are MPG 2 -  Audio: 48,000 Hz, Stereo, AC-3

thank you

The waveforms are drawn from a seperate file to the actual audio blah.wav (blah.sfk). I also get some dropouts and stutters on playback, but not on the render. If you're getting stutters on the render, try deleting your SFK file. Vegas will recreate it from the actual audio, and you can see if there is something really going on with that file. Otherwise, I just put up with it. Like low res previews, sometimes the PC is just doing too much and can't keep up.

Actually I had a bit of a win the other day. I used MSconfig.Exe to to disable all the Adobe Creative Cloud Services that launch on startup, just in case you're working in Photoshop today. They're pretty agressive memory / bandwidth hogs.

I don't understand why companies do that 'launch on startup' thing.

It's like - Today I am NOT using the Office suite, so don't waste my CPU cycles, Interrupts, bandwidth and memory. I don't want Skype always running, today I'm Vlogging. Oh now I AM tidying something up in Photoshop, but I really don't need the autocad launch assistant or Steam. Hell, If I need VPN, I'll wait 2 more seconds for the service to start - I don't need it on standby.

I would try converting the audio to a WAV file. AC3, although editors have been forced to use it, is really a delivery format. Not designed to be edited.

Berhaps there's a hidden volume envelope. Keyboard shortcut " V ".
