Worked when i tried it.

Before (on Auto):

After setting it to AC3:

Also, like gnattu mentioned JMP has it's own audio settings.  Go to settings then client settings, from there you can try to pass-through AC3, if your outputting via HDMI. (that shouldn't make a difference if your source is AAC, but wanted you to know about the options in that menu)
