You must select the Profile, or encoding instructions in DVDFab, to match the capabilities of your playback device. What types of audio does your device accept? AC-3 (you got this probably if you used one of the profiles that says "audiocopy") MP3, AAC, all of which are available by choosing the correct profile. DVDFab has a tutorial. You can access it from the red link in my sig below, or at the DVDFab.com website: just click on the Tutorial link. You might want to look it over first to get the most out of your free trial period.
