Envy24-based cards have two parts: (1) the codec, that's in charge of the analog to digital conversion and (2) the envy24 chip that does the interface between the codec and the PCI bus. There's a driver for the envy24 chip but the codecs of your card (wolfson 8776) are not supported yet. Codecs are well documented and simple to handle. The hard part is to figure out how codecs are connected to the envy chip. Unless you find the datasheet of your card, you can look at other operating system drivers. Let me know if you need further information. -- Alexandre
