The Ensoniq Soundscape S-2000 is know for electrolytic capacitor failure. If a game like Warcraft 2 correctly detects the card, it is very likely that you don't have a software problem. As long as the mixer levels are set correctly (you can verify them using SSINIT), Warcraft 2 should just work (TM). In Warcraft 2, the card should be able to play music using the "General MIDI" choice, and digitized sound using the "Ensoniq Soundscape" choice. If both fail to reproduce sound, the failure has to be in the analog section of the card. The digital part generating MIDI music is completely separate from the AD1848 SoundPort chip used by Warcraft 2 for digital sound playback.

By the way: The card you show is not an Ensoniq Soundscape S-2000, but an Ensoniq Soundscape Elite. The Elite has the pin-header connectors for the add-on effect processor board. The original S-2000 has no support for the effect processor upgrade. It shouldn't matter, though, as the Ensoniq Soundscape software packages you can find on the Internet are new enough to support both the S-2000 and the Elite.

If the problem is in the analog part, then where should I start repairing, with capacitors?
As you can see, there is no sound in either GM or FM in Warcraft2.

FM emulation of the Soundscape is awful, and implemented in the MIDI chip, that tries to guess proper MIDI parameters from the FM values programmed by the application. I am not sure what firmware versions support FM emulation at all, but you mostly don't want to use it anyway.

Start repairing with the metal cans around the AD1848 chip. First inspect for mechanically damaged caps, before blindly replacing all capacitors. Your picture looks like C57 might be ripped from the board at the right side.

Based on your photo, the lack of audible MIDI music playback is potentially due to a pair of missing jumpers.

The Soundscape Elite has a small daughterboard or ESP board attached to it. This board is connected by means of 2 - 26 pin connectors. The Soundscape Rev. 2 has no ESP board, so the 26 pin connectors are exposed. These connectors are labeled on the Soundscape board as J12 and J13. J12 is closer to the CD-ROM interface connections, and J13 is closer to the silver edge of the card. If the ESP board is disconnected from the Elite, the first two pairs of pins (1-2, 3-4) on J12 must be connected to bridge signal flow. Two jumpers are needed for this. Pins 1-2 and 3-4 on J12 are the two pairs closest to the "J12" imprint on the board. The Soundscape Rev. 2 should always have the first two pairs of pins on J12 connected.

Tip: If the two pairs of pins on J12 are not connected, MIDI will not work. Although It will appear to be playing on your computer, you will not hear any sound.

Concerning digital audio playback, it looks like your card is configured to use the F44H address. Try jumpering it to use the default, 534H CODEC address instead.

... which also explains the lack of audible music for "FM" playback, because FM emulation is also handled by the MIDI part. Good catch!

Thank you, your hints helped and soundcard works.
