AEO-Light on mac (not generating file with audio)

[neelyre]

Hi.

novice to the AEO-light software, but have followed instructions pretty thoroughly so not sure what I am missing.

Transferred sample of an old 16mm sound film, both image and optical sound waves. Exported out a 1080p quicktime. Imported into AEO, assigned soundtrack frame borders properly as well as picture strip. 

However, when I try to create a sample or even just export the whole quicktime, it generates a .wav with NO audio. Not even a weak signal, NOTHING. I know this film has audio, but for what it's worth, I even downloaded a sample clip from the AEO website to be certain that it isn't my captured file. Again, no actual audio created in resultant audio file.

My computer is an older Mac pro (early 2008 model) w/2.8 quad core intel xeon, ATI Radeon HD2600XT 256 mb. I believe this model by spec has Open GL 3.3 according to apple's website. Not sure if I have to activate it(?). It is running El Capitan.

Any help would be great in resolving this. Thank You.
