I'm not going to start throwing insults at anybody. And you can squirt and do all you wish but SB16 issues in some old SBpro-only games exist. There is no doubt about it.

I can say that in my AUTOEXEC.BAT file there is SET BLASTER T4 and these issues are still same. If I choose in PoP setup my SP Pro clone card (EWS64, Crystal 4236B) I can switch "Sound Blaster" or "ADLib" mode and sounds really play as 8-bit digital or FM. If I choose in PoP setup my SB16 card (AWE64) I can switch it too but in game I hear only FM sounds like ADLib mode.

I’m not sure what that proves, probably nothing. In any case the digital part of the AWE64 isn’t the same as an SB16.It has a less buggy DSP

If you mean hanging notes bug it's MPU part and isn't relevant to 8-bit SB Pro mode issues. What do you really mean "less buggy" if not MPU part?

To the OP, you have a powerful dos machine and I would try to get the AWE64 working as its a great stand alone card with bug free midi.....

The CQM on my soundblaster 32 is pretty much identical to the real thing, unless your a purist wanker I wouldn't bother trying to get the authentic thing because I never noticed anything unusual going back and playing games from my childhood, they sound exactly as I remembered!

All sorts of things exist. The other way as well. For instance, I have games (like Commander Keen, Bio Menace, some versions of Jill of the Jungle) that frequently fail to detect the audio card when I use an SBPro clone (like Audician 32, and I recall having similar problems with an ESS688 when I had one a long time ago), but never once fail when an SB16/AWE64 is used. In fact, I recall that this was one of the reasons I wanted to ditch that ESS688 for a 'genuine' Creative in the first place. Go figure.

Then I have to conclude that it's something specific to your system or to some class of systems. When I choose Adlib in PoP, the sound effects are distinctly different. In fact, they sound like PC Speaker sounds, not FM sounds at all. When I choose Sound Blaster, I get digital audio just fine both with AWE64 and Audician 32.

You can choose to believe me or not, but for myself I feel that I got to the bottom of it. If you continue saying that SB16/AWE64 generally cannot play digital sounds in PoP 1.3, I will continue pointing out that you are wrong.

I actually have a suspicion that the problem you experience have to do not with the AWE64, but with your dual-card setup (assuming you were running your tests on the system that has the two sound cards).

Nothing to do with MPU or hanging notes, buggy DSP with single cycle DMA

Dr_st 😀 No, I did it with single AWE64. Suspicion is false unfortunately. And if it could be so simple solution I would know about it already.
No, I pulled out all devices to check it truly a long time ago.

Ivader, OK, I'll check it today/tomorrow with my 2940, 4520, 3900 and 4390 cards once again. And with T4/T6 parameters.

DSP 4.0x to 4.13 are affected.

OK. I've repeated several SB16/AWE cards PoP running on a few systems.
Duron-1200 --- FM
Pentium II-266 --- SFX!!!
Core2Duo downclocked to 1,33GHz --- FM
Core2Duo downclocked to 166MHz --- SFX!!!
It depends to system speed. It not depends to T4/T6 values.
It is possible to recheck it on P3-500, P3-1000, P4-1600, P4 downclocked to 200MHz. But I think everything became clear.

My system where it works with SFX is a K6-II @500MHz. This might give an idea of where things start breaking.
