ASUS P5B SoundMAX audio driver for Windows 7 32 / 64 bit
ADI1988A AD1988A ADI1988 AD1988 Sonic Focus Asus P5B Analog Devices driver for W7

This is latest original (unchanged) SOUNDMAX audio driver (version 610X6585) for W7 from ASUS for P5B MB. This Analog Devices soundMAX audio driver include sonic focus effects.
I added it here because asus does not update drivers for P5B MB



I recommend you to use SoundMAX BlackHawk driver I modded to support and AD1988A. It is also available for download in windows section of this site
