Hi all, I'm a little behind Mike and Leonard here. I'm trying to install the sample src/audio/sysfx APO in the WDK 5600, running on Vista RC1. I've built the DLLs, but right-clicking on sysfx.inf gives the error: "The INF file you selected does not support this method of installation" I've also tried navigating to the Intel HD audio driver in the control panel and updating this, but it doesn't detect a valid driver. So how do you install the sample APO driver? Thanks, Roger Butler. ____________________________________________________ Do you Yahoo!?
