Audio Bizarro

[Kelly Griffin]

I’ve got the same problem as Dale, and I’ve had it happen putting a music clip on a brand new, empty timeline. Typically plays to the end of the clip, then instead of the last few notes I’ll hear part of a VO from somewhere.

Yes, no such luck as underlying music events. I have tried many workaround possibilities, but the phantom sound continues to appear intermittently and randomly (within the same unchanged project).

I am talking to Sony about this and hopefully they will be able to reproduce the audio error and provide advice.

Let us know what it is when you find out. Good luck,

I seem to have narrowed my “phantom sound” problems to the use of my new USB 3.0 external drives. Copying the problem project to an internal drive or a USB 2.0 external drive does not produce the same problem.

I have tried these tests many times and the problem is fairly consistent when using the WD USB 3.0 external drives (even through the USB 2.0 ports). I have not been able to reproduce the problem on non-USB 3.0 drives.

So, in my case, this does not appear to be a Vegas issue—which is very good news. I’ll miss my fast USB 3.0 drives, though.

Kelly, if you have your source material on any external drives, you may want to run similar tests. Seems like you had mentioned that you are not using USB 3.0, but I would test any external drive, since you describe a similar phantom sound problem.

Dale: I disabled my USB 3 the same day you mentioned you had it. I haven’t done a thorough troubleshoot, but I tend to think I haven’t noticed the problem since doing that. I’ll keep my fingers crossed that that was the culprit.

Wow, I would have never thought that USB 3.0 could be the culprit. Please keep us updated as you find out more.

Changing to USB 3.0 ext source drives was the only change I did (that I could think of) other than the update to 10c, that preceeded the problem. SonyTech had responded initially to my phantom sound problem, but haven’t replied yet to the additional info that I sent them. I am curious if they are able to reproduce the problem and comment on it.

Anyway, my tests continue to support USB 3.0 as the culprit. So, I am back to my USB 2.0s again and all is well. I have not yet experienced these phantom sounds with USB 2.0 source drives.

Kelly, have you concluded the the problem was with your USB 3.0 drive?

I still have no “phantom sound” problems when using USB 2.0. But, when I return to USB 3.0, the audio anomalies return.

Sony states that there is no known problem, but I hope that 10d magically makes “my” audio/USB3 problem go away. I like my USB3 drives.

Dale– I’m not sure what to “conclude” about this, because I haven’t had a lot of consistent time on Vegas lately to know for sure. But, the last few times I’ve worked on stuff I don’t recall having any of the phantom audio anomalies I was having before I disabled the USB3 port.
