This chipset is a Sound Blaster Pro 2. If you have any question, please contact us via E-mail or Trademanager. I don’t know if this is the correct name. ZIP, and you must remember to move those patch files into C: OPTi chips were used on off-brand cards that are anything but rare.

The GUS Classic does that by default.

There is no driver for AD Some sound cards can use the same IRQ for native mode as for Sound Blaster emulation without a conflict.

Added jumper J6 and pin header P2, functions unknown.

I have tested examples of the latter two. If you boot Windows and install this 3-floppy package available at ftp: I don’t know if this is the correct name.

Discrete sound cards based on these chips are not as common as Sound Blasters and OPTi-based cards but they are gettable. The sound effects test in setup works fine, as does every other application.

Cleaning those cruddy contacts didn’t help. Wait, stop the presses: If the items are defective, please notify us within 3 days of delivery.

The synth device is exposed by ALSA, but nq can only play silence because there is no patchloader. The module is snd-opl3sa2. If you have any question, please contact us via E-mail or Trademanager. A similar, but less detailed, listing of devices can be obtained via aplay —l. Fortunately, ALSA does have a driver for this variant. The bass and treble controls even work.

This fix was applied in kernel 3. Utopia provided both 8 MiB and 16 MiB replacements. Please contact us directly and we will use your preferred ways. Maybe it’s a feature to avoid the old “stupid user set the volume to zero” problem.

Not exactly what you want? The control labelled “FM” in alsamixer adjusts the volume of both synths, but FM is intrinsically louder. This problem is resolved by pressing the reset button. I tested two of these that came in the as-is EBay lot. Is it a sin to sharpie on a legend?

Crystal audio chips in the series from CS through CS appear frequently as the integrated audio on motherboards, where they provide Sound Blaster Pro 2.


We are not responsible for any accidents, delays or other issues caused by the forwarder. The only thing left for the audio hardware to do is the digital-to-analog conversion. ESS quit supporting their legacy products some time between and The sound tests in DN3D setup sounded right but in the game itself the music was fs4235.


EXE, that only runs under Windows. Code for the microcontroller has to be uploaded at boot time. Yet another case of Ce4235 drivers buried within a Windows executable. DN3D sound effects come only through the right speaker. DOS setup for this card is infamous if not epic and deserves its own page.
