P3D v5 Replacing default sound files

[DragonflightDesign]

I want to temporarily replace a default sound file during a check routine; specifically the autopilot disconnect sound. I have a suspicion that the default files may be locked while the sim is active because I don't seem to be able to do it. The absolute paths in the code are created at load time using GetModuleFilename to locate where the sim is running.

                // Silence the autopilot disconnect
                memset(ap_name, 0, 256);
                memset(ap_replace, 0, 256);
                strncpy(ap_name, globalSounds, strlen(globalSounds));   // globalSounds is the absolute path to the sim's \sound folder
                strncat(ap_name, "caapdis.wav\0", 12);
                strncpy(ap_replace, soundPath, strlen(soundPath));      // soundPath is the absolute path to the simobject's \sound folder
                strncat(ap_replace, "caapdis_s.wav\0", 14);
                if (findFile(ap_name) == TRUE)                          // findFile checks that the file does actually exist
                {
                    if (findFile(ap_replace) == TRUE)
                    {
                       // Both if these return -1 (failure)
                        chd = remove(ap_name);
                        chd = rename(ap_name,ap_replace);
                    }
                }

Yes, I am aware that this could cause a problem if there is a CTD while caapdis.wav has been replaced.

Is this for FS2020? If so, just one more reason to not develop for that mess... Yeesh!

Nah - P3D, Ed. Tag added.

Confirmed the files are locked. Just tried moving the caapdis.wav file when P3D was running and got 'The action cannot be completed because the file is open in Prepar3d exe'.

In the sound.cfg file there is an entry named AP_DISENGAGE_SOUND and you can add flags=1 to disable the sound so that your own disconnect sound is the only one that plays. This assumes you are developing for a specific aircraft.

Many, many thanks Ed. I know nothing about the sound.cfg file, so now that's one more thing on the list to learn.
