The SoundBlaster 32 and AWE32 use different chipsets; if you have a standard 32, don’t expect support for it from the AWE32 driver in R4. (Functionally, the only difference between a 32 and an AWE32 is that the AWE32 has 512K of on-board memory).
Fortunately, the 32 is supported by the SB16 driver. Download the SB16 driver from BeWare and you’ll be all set — you’ll even get MIDI support (which the SB16 doesn’t do).
