Hello all I am a first time user of PAX drivers and hoping it can fix the crackling and popping I get after a few months use. When I re-install official drivers all is well for a random time frame and then the popping and crackling returns. What I need to know is how to install the PAX drivers AFTER I have installed the official ones. W7 seems to have been over looked but it also seems possible to just update the drivers from the PAX folder for both the SB audio controller and SB z devices in device manager. What I am thinking is correct: Select device in manager and "update from list" and the choose "have disk" for both devices and select the ONLY option available in that folder (Downlaods folder.....PAX\Audio\program files\Creative\Sound Blaster Z-Series\Program\Driver) which is "ctHda" I presume I do this for both devices in Windows 7 and then that is it right?
