I used the CT-VOICE.DRV which comes with the AWE64 DOS driver (found in the C:\SB16\DRV directory).
I'm not too familiar with the different variations of this file though. If there's another version than I can try, let me know.
Yeah, there are a bit TOO many variations of this file, I've also had to search quite a bit to make it work...
I've attached the ones that work for me (for SB PRO and SB 16). I've just tested the SB16 version with the AWE64 and it works fine (once the speed gets below ~ Pentium 100 - 133 MHz).
So, in the meantime, I plugged the AWE64 (CT4520) in a VIA C3 Ezra-T/440BX build that I have on my desk.
When it comes to speed sensitivity, yeah, it's pretty much like I remember it. (i.e. in my case, on this platform, even Prince of Persia refuses to initialize both FM and digital sounds and reverts to PC Speaker sound, unless I get the speed below that of a Pentium 100 - 133 MHz). Furthermore, even when the CPU speed is lowered, the card (or its drivers) tends to behave erratically when launching multiple games in one session without rebooting (after running 5 - 10 games, I was experiencing weird issues with games like Duke3D, Lion King, Jazz Jackrabbit that were refusing to properly initialize the sound or simply crashing altogether; upon rebooting, the games ran fine). Here's a sample with this behavior when it occurred in Duke3D.
After testing almost 20 games (again), I would say that CQM can be tolerable in some games, while (for me) being unbearable in others. All in all, I would much rather have an OPL3 or ESFM card and enjoy all games with proper sound (FM synth). 😁
One thing I like about this card, though, is the fact that the PC speaker input works properly and sound can be heard in both the left and the right channels (as opposed to some cards like the ES1688 that for some reason redirect the PC speaker to the left channel only).
Just in case anyone is interested, here's some AWE64 Value CT4520 samples that I recorded in the following games (you can find the playlist here):
01. Prince of Persia (PC speaker - speed sensitivity behavior)
02. Prince of Persia (CQM)
03. Dyna Blaster (CQM)
04. Indiana Jones and the Fate of Atlantis (CQM)
05. Monkey Island (CQM)
06. Monkey Island 2 (CQM)
07. Titus the Fox (CQM - speed sensitivity issues/missing sound samples) - this game usually initializes the sound properly only with CPUs slower than 486-DX33. If CPU speed is greater than that, it's either missing quite a few sound samples (as shown here), or simply reverts to PC Speaker. I was actually surprised that, at this speed (~ Pentium 133 equivalent), with the AWE64, it was still able to detect the FM chip (albeit with missing sound samples).
08. Titus the Fox (CQM - proper speed ~ 486SX-25)
09. Super Nibbly (CQM)
10. Volfied (CQM)
11. Duke Nukem 3D (CQM)
12. Doom (CQM)
13. Lemmings (CQM)
14. Prehistorik (CQM)
15. Loom (CQM)
