PandaBoard HIL, Having problem with audio pipe via simulink. Can run script remotely?

Attempting to run a simple audio loop through the pandaboard support package. Downloaded, installed package, network setup, host has successfully assembled my executable and placed it in the specified directory, except the program doesn't work.

Pandaboard with Ubuntu 12.04 LTS desktop. Simulink: ALSA audio in --->>> ALSA audio out (simple pipe)

When typing ps -e, the "PandaAudioMod"(my test) process is running, but the audio is not coming through. Using default device settings in the alsa blocks, 44100hz. Host computer sending signal via headphones to the mic in the panda, want to listen in on headphones on pandaboard.

Instead, is it possible to run a script I have created remotely on the board?
