China DOS Union

I downloaded the official driver for DOS,
but it has to be installed under 98.
After installing it, if I run the configuration program under DOS, it can produce sound and adjust volume and other settings.

But when running pqv252 and mpxplay, they still say they can't find the sound card or something like that.

What's going on here~

I used a Yamaha 724 sound card before. For it to produce sound correctly under DOS, it also needs an SB-LINK cable connected to the motherboard's SB-LINK port, to occupy a DMA channel that a DOS sound card must have. The problem is that on current motherboards you can't find an SB-LINK port anymore.

I remember that in a 98 window, pqv could produce sound. Is that because it was using the 98 driver?
My board is relatively old, maybe it still has that interface.

Let me ask, what kind of connector is it, and how do you connect it?
Thanks

The connector is double-row, 12 pins or 14 pins total, with one pin missing. The Gigabyte 686LX3 motherboard I used before had this connector.
