All of my Sony software products have gone silent. I have Vegas, Cinescore and Screenblast SoundForge. I can still play music on Media Player so it isn't speakers or system related. All three products show the sound wave on the time line and if I click play the meters act like the music is playing. Recent .veg files that worked when I saved them don't have sound now. Mute is not turned on and I can't see any other obvious explanation. Any ideas what could make my Sony products mute?
Thanks,
David
