I've checked these forums and also searched the web and found similar problems to mine but not exactly the same. Thus my posting..
I am trying to edit an existing .mpg video. I import the video and drag it to the time line. The video and audio both sow in the timeline and the audio track has the wave form. However, when I play the video in Vegas the sound can not be heard. Also, on the Project Media tab, when I play the video, the volume levels don't raise or lower as the video is playing but they do in the Trimmer window.
I have opened the video in other programs such as DVD Architect, and Sound Forge and it works fine. I have checked the Preferences and the setting seem fine.
I also opened some other videos that previously worked fine in Vegas and the audio isn't playing in those either now.
It was working fine just two days ago and I haven't install anything new or anything else...
Any help is greatly appreciated.
