Got my card today. Working as intended based on limited tests on my SIS530 SS7 box.
Few observations:
- Officials drivers do set environment BLASTER value to T4 (SBPro). Impulse Tracker, XTC-Play, ... do detect card correctly SB16. I guess detection is done based on DSP version and env variable is ignored.
- Adlib Tracker II while detecting OPL3 capable card correctly is outputting random noise. RAD player is playing correctly. Games with FM music support are working correctly. Edit: looks like it's about timing issue. adt2play.exe command line player included with tracker works with /latency parameter.
- Fast tracker v2.12 seems to be detecting card correctly but refuses to start payback.
- Second Reality demo is in stereo, so this card sports poor SB16 emulation 😉 However I hear slight click's/breaks in music playback with 2-3 sec intervals.
I will over the weekend test it on my 486 and BX (P3) systems. Perhaps issues above is SIS530 chipset related.
btw. Are there any playback fidelity differences between SB16 and WSS implementation. If program supports both which should be preferred one? On paper both are 44khz/16bit capable. With my ears I could not hear clear differences. Tested with Cubic Player and Inertia Player.
