Yes, I am mostly interested in the OPL sound. And the info about ALS100 not supporting all the OPL channels surprises me. I need to check this with the good old ALS007 (the card I have is equipped with some YMF262 clone, but now that I have few dozens of genuine YMF-s I can upgrade all these cards I have).
We're little bit off topic, but... Long story short:
I've bought ALS100 based card because it had external OPL3 clone, not their custom synthesizer.
The card played PCM just fine (although, a little too quiet), but FM was a complete scratch and hiss.
I suspected broken OPL3 clone. No, it was broken 74LS245 - which I've changed to 74HCT245...
However, because I had genuine YMF262 I decided to replace it. And what turned out ?
There is no audible difference between the two ! Well, at least for me.
Than I started to analyze schematics of the card, and figured out that only half of the outputs are connected to ALS100 chip.
I may start separate thread about this card.
Also my last purchase - SB Vibra 16s (CT2800) with real OPL3, behaves the same - only OPL2, not OPL3.
