Ok heres a theory (bare with me)
Since windows 7 first came out, I have downloaded many driver updates and gradually the sound had gotten worse and worse.. however right before 2.32 came out I had just installed windows 7 rtm (night before). I wonder if realtek drivers are leaving old files behind and corrupting newer updates. only reason i say this is because 2.32 is working perfectly fine and i think if i had the rc still.. it would not. hope that makes sense. since the last 5 updates or so, my windows log on screen had been making ridiculous noises and now theres nothing but beautiful sounds
