Is there any way to turn off (or down) certain interface sounds?

I think I've identified the sound you're talking about. Can you confirm that the attached wav is correct? The file is located in sound.pack. Specifically it's \sfx\hud\campaign\emp_hyb_campaign_popups_set_v1.00_gme.wav . It should be possible to edit the file to lower the volume and include it in a mod pack file. Haven't tried replacing UI sounds before.

edit: Whoops, just checked in game and that wasn't quite the right sound (very close though). I'll keep looking and post back.

edit: OK, found the correct sounds. There's actually 2 or 3 sounds for cycling/selecting items on the campaign map. The sound I believe you're talking about is for buildings. There's a separate sound for characters/armies which is less percussive (sounds like sticks) as well as a more subtle drum for simply mousing over a city. These could all be normalized, but it sounds like the buildings clip is the one giving you grief. I'll refrain from posting the clips since they're technically unedited CA originals, but if you'll confirm which ones are bothersome, I can either post a mod lowering them or instructions on how to do so.
