Ok so I have uploaded the original source for the SGH-T939 to my old website since it's better than using them stupid free services. I'll keep it there for a few weeks so you guys can download it. I guess what your looking for is in the kernel source folder under sound (maybe). To give you an idea of what is included here is some ls snapshots.
In ./kernel/sound
Code:
ac97_bus.c
aoa
arm
core
drivers
i2c

Kconfig
last.c
Makefile

oss
parisc
pci
pcmcia
ppc
sh
soc
sound_core.c
sound_firmware.c
sparc
spi
synth
usb
In ./kernel/drivers is this
Code:
accessibility

That is among a ton of other things included in the package (has the original cupcake build scripts as well).
Hopefully this helps, if I have more time I'll see what else I can do to help. For now, good luck!
