Is it possible to run ASUS Xonar STX on OS X system?

Question

ASUS

There is a computer with OS X Mavericks 10.9.4 installed on an ssd disk (hackintosh).
An ASUS Xonar Essence STX sound card is inserted into the PCI Express slot of this computer, which, as you know, is hopelessly incompatible with macos (because nothing is written for it to work under osx?).
The question of interest is whether it is possible by writing a certain kext to still make this card work in the osx system or is it in principle not compatible at the hardware level? Google has an example that this card is able to communicate with unix systems (using linux as an example) so I assume that theoretically this is real.
If this is possible, then the next question follows from this - is there a chance that someone will undertake to perform such a task (for example, on frinaslim.ru) and how much can it cost? The final result should be able to send sound to the card and manage it no worse than the windows driver can (control the surround, mixer, etc.).
PS - running the card inside a virtual machine (windows for example) running in osx via PCI forwarding (VT-d) is not interesting, you need the card *natively* to work inside the macos.

Answer 1

For 4 years, no one has written such a kext yet. In practice, this is real, but the question of cost, time and availability of documentation.
In my opinion, it is better to take ESI [email protected] XTe or a similar card with OS X support from the manufacturer. Most likely it will be cheaper than writing a driver.

Answer 2

Yes it exists for several years. I compiled it from the source I found on internet and created kext driver.
