Without sound in Sony Vegas

[iGladozZ]

Hello to all. Always render correctly with YAMB video to read the Sony Vegas. When I put it on Sony Vegas 9 is not heard.
Before I had the problem that was not seen then install QuickTime 7.65 and now can be seen, but is not heard.
I have all the codecs installed, what can that be?

Thanks

Check if your file have 5.1 audio. Ticked "Allow multi-channel audio recording". If yes, turn it off next time.

I need you record the voice and the sound of the system for my videos...

Yes you do, but you don't really need a multi-channel audio recording. You can leave that box unticked. Just make sure you have selected Record system sounds and from the Microphone scrolling menu "Always record". Optionally you can check Record microphone into separate audio track if you need two audio paths. One for system sounds and one for your microphone.
