I was able to solve this myself. But, in case anyone else has a similar issue (which I doubt, lol) it was my own doing. I had a bad habit of right clicking on and audio track to then choose “Add Track” rather than “Add Track(s)”. The benefit for me was that it created another track right below the one I was on rather than bringing up a dialog box where I would have to decide on placement, tell it I didn’t want to add any video tracks, etc. The problem is that it would duplicate the settings of whatever track I was on. So if I happened to be on a mono track, I’d get a mono track. Now, it would be logical (to me) that Adobe show somewhere in the interface what type of audio track you have (and even give you the option to change it after your created it maybe?) but I’ll take the blame here and admit it was a bad habit on my part and resulted in a number of mono tracks that I was unaware were mono, figuring “standard” would be the default when creating tracks. So… my files were playing back in mono simply because they were dropped into a mono track.

The way I found this out was (as far as i know) the only way to see what kind of audio tracks you have in your sequence, by creating a new sequence File–>New Sequence, then clicking on Tracks, then choosing “Load from Sequence”, selecting the sequence you want and then it will show you all the tracks and track types. SMH. This is the only place I’ve found to see what type of audio tracks you have in a sequence after they’ve already been created.
