I re-purposed an SAS 5/IR RAID card status cable to link my pentium II motherboard speaker connection to the AWE64 - Might and Magic 3 sounds so much better, and the speech is pretty decent.
Need to check the CD audio cable is working tonight, and then that's pretty much a completed build, case will be staying on. p2 300MHz, 384MB, Intel NIC, Geforce MX400, Voodoo 2, Musicquest MIDI card, AWE64, an SSD, and HxC floppy/SD card. The XP/Windows 8 gaming box is also in what is likely to be its final state, so it's only the 486 that now needs building (underclock a DX2-66 to a DX2-40, stick in a Reelmagic card, SB16, and a 5.25" floppy).
Also tried playing Sam and Max, and found the same hanging issues as everyone else when trying to have SoundBlaster sound and General MIDI music. If run under OS/2 it prints out a stack trace before hanging.
I'm sure I have had it working, may well try getting it working on the 486.
