After all of this time I finally realized this very annoying noise plays as soon as I advance to the Ready to Load page in the FCDU. It's irritating, and it's not just a white noise w/ a steady sound. It has some recurrent 'tick tick tick...tick tick....tick tick tick' sound that comes thru the white background noise. I thought it was something in Prepar3D all of this time and finally realized it's coming from FSCaptain. I tried testing the various .wav files in the Sounds folder in FSC and none of them create this sound. It persists and is heard over all other sounds in P3D. It stops when I close P3D. It does not start until I get to the Ready to Load page.
Any ideas what this might be, and how to eliminate it or reduce its volume? I'm using P3Dv4.5 and installed the latest FSCaptain from around March or so.
Thanks! I hope you can help with this it will be so nice to lose that!
