Alright I've played around with things some more but still have not got anymore progress.
The card does work in Windows (tested in 98 and XP), in terms of hardware... things are probably newer than they would ideally be. Specifically a Pentium 4 @ 3.2Ghz in a Gigabyte GA-8IPE1000 Pro2. I do have the options in the BIOS to set a specific IRQ to a PCI slot if that helps but i don't believe that is the problem as it looks like the driver detects the card when it loads.
I tried the driver Jo22 mentioned (found here PCI Sound card for Windows 3.11 & Dos 6.22?) in DOS with Windows 3.11 (the installer wanted Windows) but the install did not detect the card and refused to install.
I have tried ES1370 drivers that i found here DOS sound with Ensoniq ES1370 PCI but when APINIT.COM was called by AUTOEXEC.BAT i got the following error message.

error: PCI audio legacy device was not detected
If i run Wolfenstien 3D it does not detect any sound output methods except for PC speaker. So far i get the feeling its a driver issue and that i'm just doing something wrong...
