Momentary pause in Sound when using Flash Player AND Flash CS4

Question

Hello,
When ever I play something in Adobe Flash Player (a flash movie, for example) and there is an absence of sound, the flash player will momentarily pause (for about 1 second) RIGHT BEFORE an incoming sound is made.
Imagine in the movie someone swings a hammer towards a plank. The animation will pause RIGHT BEFORE the hammer makes an impact and thus creates the hitting sound. The sound and animation will time up correctly, but there is that brief pause before, as if the internet browser, or flash player, or my sound card has to 'load' something before executing the sound.
I tried experimenting with my sound output via the bottom-right hand control properties on the desktop, and when I choose "Digital Output Device (SPDIF)" and disable my "SigmaTel High Definition Audio CODEC," there is absolutely NO sound at all, yet there is also NO lag prior to where a sound would play in the movie. This leads me to believe it may be a problem with my sound card.
As I said before, if the Flash player is playing a continuous sound, a background song, for instance, there is no momentary pause when the introduction of new sounds happens.
I've tried uninstalling and reinstalling the player - no luck. Obviously i'm currently running the player at the newest version.
OS: Windows Vista Home Basic
