I've run into this problem twice now, I have flyers on a ground map and have ALL the other sounds added correctly and working except that I can't seem to get the 2nd position Y-Wing turret to make any noise (no turret swivel, no warm-up, no firing)...and nothing remaining in the space sfx file looks at all related to Ywing chain guns...does anyone know for sure which lines are for the chain gun, or if it's even possible to get those sounds working?

The same sound works fine in CW era (well, I think its the same sound, anyway; droid trifighter's main cannon/atte rear cannon?)

When I was working on my conversions, I ran into this problem too. I don't remember how I got it working, I think Pandemic misspelled the sound name.

I had the same problem also, with my Dune Sea Sunset conversion, so in the end I just took the Y-Wing out. I tried severel different .sfx sounds to no avail.
