Re: Adding an Audio Track in DVD A

it is as simple as dragging it from the explorer window into the timeline, below the main audio track. Just did it now, so am not sure why your audio isn't working.

once done, can select audio during preview, to make sure all is working.

try dragging something from your music folder, i.e. mp3 or similar, to exclude any audio you have rendered yourself (eliminate variables)

you could also use the '+' button on the timeline toolbar to add an extra audio track, then click TRACK MEDIA in top right properties window, and then REPLACE the audio for that new track.
