So quick update - I received the following in the mail:
Sound Blaster 32 (CT3930) w/ 2x256KB SIMMS
GeForce Ti4600 AGP
Sound Blaster Live! Platinum w/ Live drive and original accessories
After installing everything, I installed the AWE32 drivers from the Vogons drivers library. Tried some games, and at first in games like Doom and Doom 2 the music is so soft that I basically can't hear it. I tried the SB16 utility to set mixer levels and it seemed to help a bit, but I wonder if there are updated files for the SB32 that would be better.
Next, I tried Tie Fighter, set the FX and music to AWE32 and wow - I can't believe how good the music sounds now. So much more symphonic and vibrant than the SB Pro 2.0. With XWing CD though I can't get any music unless I set the sound to SB16, and even then it's not as good as Tie Fighter.
I noticed that my DOS games run so smooth in VESA modes with the Ti4600. The card is pretty silent too, as I was worried about reading reviews on it. But I scrubbed the old dried thermal gunk off (ultimately resorting to using a hefty razor on the heatsink) and applied fresh MX4 which I think made a difference.
All-in-all I am impressed with the jump to the SB32, and plan on upgrading the RAM to 32MB and try loading a soundfont in DOS, then perhaps Win 98. Is it better to run this card in GM or GS mode, and in extended midi or general midi? It seemed that general midi worked a bit better.
Oh, and now I can play Day of the Tentacle again without buzzing or lockups. Sounds great too, but I have to set the sound buffers to 8 for it to work.
Unfortunately I have to reinstall Win98 because when installing the AWE32 drivers I also did the windows drivers, not thinking that they were for Win 3.1, which hosed my install. Oh well. I really want to get through it and start trying some Win98 games with the Ti4600 though. I hope Undying works better.
I should post a picture of the Live! This thing came practically brand new, and with full Descent and Thief discs (which I didn't expect) in a seemingly unopened accessories bag! Really excited about that. Question - if I use some kind of y cable to put both sound cards to output to my speakers, will there be feedback? I want to have sound in DOS (SB32) and Win98 (Live!) without switching the cable out every time.
