You need a driver for the AC97 controller your system is using (for most
ARM systems this is part of the CPU). Since AC97 provides a standard
register interface for CODECs Linux does not require specific support
for individual AC97 CODECs in order to get core functionality working.
You can check if there's any specific CODEC support in sound/pci/ac97.
