Does the S2 have a power or activity LED btw? Any sign that it is getting power?

I don't recall ever seeing a power LED on any of my wavetable cards on any computer.

Nope.

X2GS has a LED, that's why I asked. Did you try toggling the joystick option in the BIOS?

Yes, I tried it with joystick option enabled and disabled. Also tried with midi option enabled/disabled.

I was told that the latest revision of the Chil 'n Phil has an LED activity indicator, but I don't have this unit.

Opti MAD16 82C928 that is kinda on the horrible category when it comes to compatibility.
It is just another SBPRO and WSS compatible chip, like the majority of 3rd party chips.

My Yamaha SW20-PC has an Opti 82C928 and I never had any trouble with compatibility. It just worked with every game I played, in FM or MIDI.

The issue is usually with digital sound, not FM..

The TeleVideo Multimedia: Telesound Pro16. Never heard of it but it has what appears to be IDE headers for certain brands of CD-Drives (and a Sony floppy header?). I assume it's a Soundblaster 16 clone anyway.

Driver package for this card shows files named "Snd929p.vxd" etc. which is associated with the Opti 82C929 MAD16 Pro chipset. You should find this chipset under the sticker. This chipset does 16-bit audio and is SBPro/WSS/MPU-401 compatible.

Where did you find the drivers for this card? I came across this card and would like to test it out. Wayback machine shows the website but driver link for win 3.x/dos is dead.

I've been testing the on-board CMI8330 of my PC Chips M571 motherboard and I noticed something unusual. It seems that this particular (integrated) version of the card has no filter for digital audio. Not the SBPro style low-pass filter, nor the SB16 style brick-wall filter. Just nothing. If I were to compare it to another sound card, it resembles the unfiltered output of a Yamaha YMF 724/744.

I'm curious if this is something unique to the integrated version of the CMI8330 on my motherboard, or if the chip was simply designed like that. Anyone else noticed this?

Dunno yet, have to do some more tests. 20something yrs ago I had a PCChips M726 (or was it M729?) with SoundPro aka CMI8330 onboard. Back then I was not impressed.
But yesterday I tested an ISA card with same chipset, which gave me trouble in the systems I tried it long time ago; hangons, compatibility problems with games, etc.
Now I tested it on a 440BX mobo (ABIT BH6) with a Pentium III 600 and Unisound instead of CMI initializer. I was amazed... Very good channel separation, noise so low that I did not hear it and SB Pro and SB16 compatibility with every game I tried so far. Only bad I can think about is the lack of an internal DB header.

It's a certainly good card in terms of SB16/SBPro compatibility and FM synth faithfulness.

My only complaint is the aforementioned lack of filtering on my particular version, which makes digital audio sound overly harsh.

@Joseph_Joestar
I'm having the same problem with MK8330 sound card.
Using SPDIF_IN for digital CD-Audio sounds terrible. Kind of too loud/distorted.
I have to use analogue CD-Audio and always wondered why digital CD-Audio is not working with that card.
So maybe it's indeed a CMI8330 issue.

Just to clarify, when I say digital audio I mean sound effects and speech in games like Duke3D or Doom. Not just the SPDIF_IN for digital CD audio, though that is affected as well.

Speaking of which, I found SPDIF_IN for digital CD audio to be very hit and miss on my integrated CMI8330. More details here.

CMI8330 doesn't synchronize itself to SDPIF input's sample rate, it just nearest-neighbors the samples it receives to its internal sample rate, which is not exactly 44100 based due to its 14.318... MHz master clock. So it is no wonder it sounds dirty and poor. Similarly the SPDIF output is nearest-neighbored from whatever SB/WSS side rate is chosen, into close to 44100Hz derived from that 14MHz clock it uses.

Alright, I indeed messed up "digital" sound effects with digital CD-Audio.
But then I know this is not a problem of my individual card and leave it with analogue CD-Audio connection.
