If it is just a simple audio loopback you are looking for than you could try running 'cat /dev/dsp > /dev/dsp' which should have the audio driver copy the incoming audio to the output.

The DM644x currently uses an OSS driver, the source to this can be found within your LSP kernel source tree at sound\oss\dm644x. I do not know of any good audio loopback examples within the DVSDK package, though you may be able to find something using OSS on the net.
