Little trouble with some games

[coolzire]

I am a avid player of the fallout 3 and fallout new vegas and recently reinstalled window on a bigger hard drive on my laptop. I ran into issue where the in-game radio. Before the win7 codec i had no issue and after removing them the radio worked again. Both game are listed as dont use in ffdshow setting. The actual sound file appear to be mp3. I remember having no issue before while using an older version of win7 codec. The issue occur with or without the x64 component. I have win7 64 bit Professional and i mostly use the codec for thumbnail. Is there another codec that could potentially interfere with the games?
