This is WHQL driver I modded/modified to work with Asus P5B MB ( AD1988A ). Diver works on Windows Vista and Windows 7, 32bit and 64bit. Because driver is modified to works with AD1988A chip, when you run driver setup Windows warns you that driver is not certified. This is not true! Driver is WHQL signed and you can check this in device manager driver tab, after you install it. In Windows Vista was possible to load unsigned driver but on Windows 7 drivers that are not signed does not load. Because driver binaries of this driver are not modified they are WHQL signed and after driver is installed it loads as any other signed driver, without any problems. This SoundMAX BlackHawk driver works much better than latest original SoundMAX driver for Windows 7 (SoundMAX ver. 610X6585), because sound quality of BlackHawk driver is much better and also BlackHawk have not problems with sound of front panel headphones when it is configured as 5.1/7.1 and you paly 6 channels or stereo sound There are one thing you must know when you install SoundMAX BlackHawk audio driver on Windows Vista or Windows 7. When driver is installed all other channels volume except volume of left and right front speakers are set to 0 and after you configure it as 5.1/7.1 channel sound system you should set volume for all channels in order to listen sound from them. You can adjust each channel volume level from Windows sound settings or from SoundMAZ BlackHawk panel options. From SoundMAX BlackHawk panel options you can do that by opening speakers section and then to click on Regroup button to set all channels to same sound volume level To get clear sound you may need to lower sound level by lowering equalizer sliders for preset you use. To have sound play of all of your speakers on 4.1 / 5.2 / 7.1 sound systems, when you play stereo sound, you need to enable sonic focus effects with this button
