Cracking sound

[ghost]

I get a cracking sound when any dialog whit an NPC is playing and when you scroll the toolbar fast it doesn't happen in the regular game or the moded 32 bit version just the 64 bit version and at first I thought my speakers were the problem but I tested it whit my headphones and the cracking was still there. I don't think any of my mods are causing this because when I was playing on the 32 bit version it didn't happen and started happening on the 64 bit version. I would attach some mp3 files where you can hear the difference between the 64 bit version and the non moded 32 bit game but I can't and don't know how to.
