Please visit ALSA and OSS (Open Sound System) project webpages. aplay
is a user space application which calls the alsa library functions to
play the wav files. You should not use the raw interface /dev/dsp, as
was the case in OSS. Both are different projects, and you will see 
Open Sound System as deprecated (but still OMAP drivers are available)
in the menuconfig. 

I would suggest you to try OSS first. So you can easily test
with #cat test.wav > /dev/dsp :). 

In Menuconfig

Device Drivers -> Sound -> Sound Card Support -> Open Sound System ->
Open Sound System (Deprecated) -> OMAP Sound Driver -> AIC23 Stereo
codec

and build.
