Thanks for the replies; after reading your replies, I realized that in fact my mixer does say audigy 2, not zs, so I went to the creative support website and am downloading new drivers and software versions. I can't find any where to shut off record monitoring- there are no plus signs to click on and some of the menu choices like "analog mix" and there is no plus sign over the mixers volume control.
Also, in the soundcard calibration window of REW, I have selected audigy2 as input and output devices and line in and speaker as input and outputs- is that right, other than I might have been supplied the wrong driver type or may have old versions which I am now updating. My laptop has a realtek builtin sound device, so there aren''t 2 creative soundcards in the system.
