I used the leaktest.com (btw it is from 2005) and my firewall allowed the connection to proceed. I used auditymypc and nothing could get in.  so I guess one of my settings lets things out but not in. 
but now my sound is messed up.  I can use the stereo and quadraphonic with no issues, but when I switch to surround sound I get a weird underwater like sound coming from the speakers.  trying removing sound card and reinstalling it, nothing.  I have a g35headset and all sound is normal in surround sound (it is usb).  only having problems with speakers.  any ideas?  
I had blocked universal plug and play service and problem didnt go away with firewall, so i put it back on.  
sound card is sb x-fi xtreme audio, speakers are logitech 540 5.1.
