Windows 7: Realtek HD Audio Manager

I have the Realktek HD Audio Manager.

Audio Driver Version: 6.0.1.5911

DirectX Version: 11.0

Audio Controller: HD Audio

Audio Codec: ALC885

This is my issue:

I use a program called ventrilo. Sometimes the audio comes through crystal clear perfect everything, then randomly it will become softer and quiet or like I am underwater and you can't understand what I am saying.

Ventrilo:
Version: 3.05 win-x64


Can anyone help me?

Thanks,
Anomaly

was this prog for xp or vista originally?? might want to check on the vendors sight for the info you need. if it's a "slim shady" version.. you might want to run it in compatability mode. right click it and go thru properties to make it so.
