SPO-15 in the MiG-29S (possibly other FC3 modules using SPO-15) is not producing an audible signal upon detection of missile launch/seeker active. SPO-15 shows the flashing red missile seeker visual, but no longer produces the audible missile signal despite the volume being on. Tried with AIM-54, R-27ER, AIM-7, and AIM-120 with same result. Same result in both single threaded exe and multi threaded exe. Have only tried with A2A missles, haven't tried with SAMs yet.
Attached two quick tracks from a testing configuration I set up.
