I'm just posting this as an FYI for others (since I searched extensively and found nothing to help me with this specific issue).
I got myself a new Droid X, downloaded a bunch of stuff, got it set up how I wanted and a couple days later when I went to stream Pandora through my headphones I got no sound. When I unplugged the headphones, it played music through the speaker just fine, just not through my headphones. Playing with some more apps I found this to be the same with all apps including the default music player. However, I tried the FM Radio app (as I knew this app to be different as I NEEDED headphones plugged in to use it since it uses them as the FM antennae), and voila, I had sound. So it was clearly a software issue, not hardware. I knew I had the most up to date version of Android from Motorola, so I didn't know what else to do. I searched and searched but didn't find anyone else with a similar problem, but I did find a lot of posts from users with other brands/models of phones and it seems a Hard Reset might fix the problem. So that's what I did following the guide listed here:
Droid X Hard Reset (Just one addendum: You need to scroll down using the volume rocker to select factory reset after step 3, which the guide doesn't say explicitly.)
Anyway, after a hard reset and reprogramming of my phone, I tested the headphone connectivity with some music on my SD card and it worked!
So, short version:
Headphone problem --> Hard reset = fix (at least in my case)
Hope others find this useful. Now to go download all my apps again, /grumble.
