Increasing Volume for Netmeeting in Regedit

I’ve been trying to figure out a way how to increase the volume of Netmeeting because I turn it up to the max. in the program and I still can barely hear the other person. I am forced to turn up and turn down the speaker everytime I have a netmeeting conversation, which is annoying. I know where to make these changes and they are in the registry editor at HKEY_CURRENT_USER > Software > Microsoft > Conferencing > Audio Control. I’m pretty sure its the value of “Speaker Volume”, and it says “ff ff 00 00”. I think this is in hexadecimal, but what do I change to increase the value?
