FS2 + SCP won't fix the issue; however, the debug log may shed some light on it. FS2 (you can get it from gog.com for 5.99) + SCP is one way to get a debug log, however, there are a few TCs you can get that also can create one. The Babylon Project is one, however, the download size is somewhat large (750MB for the smallest version). The BtRL demo is ~300MB. Problem is, both TBP and BtRL use old builds of FS2, so I'm not sure how that will go.
Actually, you could try just running FS2 Open on WCS's data, but I'm not sure what would result, as WCS made several changes to how FS2 Open normally operates. It may function well enough to give you a debug log, though.
You could try updating your sound card drivers, just in case that fixes it. I don't think it will, but if it did it would be silly to download all that stuff... well, at least you'd get more space combat sims to play around with, but you get my point.
