I am using windows 7 64 bit pro and have a rather great build of a computer. 4GB of ram, AMD II X3 3.0gHz, 500GB HDD, realtek HD audio with up to date drivers on everything.
Our problem (my mom and I) started after I plugged in a set of cheap wireless headphones supposed to be good for chatting online. Well they are sort of good, paid low, got low quality. However we chatted before on windows live, before the headphones, things worked fine. Now they go fuzzy real quick and I don't hear her voice then I hear crackle like sound and I hear her again. She hears me fine. I plugged in my regular speakers that work great on all the rest of my software including games, movies...etc., and still no change.
I have tried reinstalling audio drivers up to date and even reinstalling my web cam. Could the problem be her old web cam, hardware issue on my end or having a conflict between her windows xp media 2005 sp2 HP Pavilion a1133w. that can not be updated to SP3?
