I am using the SONY Vegas Pro 17 and recently I was having trouble with my audio importation after I downloaded the Windows update version that is available in my license software. Do you have any upgrade solution using my Sony Vegas Pero 17 video editing software so that everything wil go back to NORMAL after having the windows update version? The audio that my daughter is experiencing in her ASUS Gaming laptop seems to have a a very inaudible sound using the mp4 music audio after importing and using it as my sound effects and background music in my video project as a Film Making student. Please let me know the solution/s to this problem. THANKs !!
