Ok, so finally got around to testing on my Tyan S1854.

I am using the modified for VIA chipsets SETUPDS.

Here is how to make it work.

1. Run "SETUPDS /s" from DOS. This will initialize the card so you can actually change stuff in the configuration.
2. Run "SETUPDS" from DOS. This will bring up the configuration/test part of the program.
3. Change the DMA mode from PC-PCI to D-DMA.
4. You can try testing the sound now. All modes should show up. When testing Sound Blaster 8-bit, it will most likely say it can't find DMA at 1. Change it to 0 and try again. It should work.
5. Save and exit. This will not update the SET BLASTER setting in Autoexec.bat. You will need to change "D1" to "D0" as well as any other settings you changed such as the I/O and IRQ.

I have had to do nothing else to make it work at least in the test portion of SETUPDS.

Is AK4544A any good? Toshiba Tecra 8200 comes with YMF754-R and AK4544A. There is also this chip called ALPS 3DA3DT336B which i have no idea what it is.

Generally I like Asahi Kasai stuff, but the AK4544A doesn't appear to be very strong from a specifications point of view.

If i were to replace it with a greater quality one, are these things usually pin compatible?
For example, rip the STAC9708(11) from an SB Live and replace it with the toshiba one.

The AC'97 bus is standardized as is the codec package, pinout, and certain performance requirements, but comparing the AKM with another stereo AC'97 codec (CS4205), it seems some pins can be used differently (GPIO for example). Beyond that, do check the application notes to make sure the requirements for output passives are the same for both chips.
