Kevin, sorry for the bad news so far.

That device came in very early during the first analog support for the
global tda8275a, but all involved tried their best.

So, we don't have the gpio settings it uses with the other driver yet
and there might be a slight chance to come something further with that.

Unfortunately this one comes only with some Asus OEM mobos, which
decreases the user base hacking on it, and another eventually related
problem is the WIFI wireless stuff on it.

These days we have multiple chip configurations, where likely every
single one can do substantially needed switching for another one later
in the row.

Asus in common keeps tracks quite well, but we have also some very
different devices with the same PCI subsystem ID already we must come
over by eeprom detection, not that easy if you don't know what is
encoded exactly where, the chip vendor is ignored with his suggestions,
even this is not public and a puzzle, and all are having fun ;)

Some seem to think right now it is only bad history these days ...

Cheers,
Hermann
