Odd sounds

[nward]

I created an issue on the Stratis repo, but I figure I should probably create it here as this gets more traffic, and I imagine it happens on Altis as well (though, I can't 100% confirm easily as I'm not running an Altis server, but if it doesn't happen with others' servers I'll run one up to check).

Anyway, when base parts spawn in, there's a loud reloading sound, like a tank or a lynx/m320 reloading sort of thing, really, really loud. Freaks people out, obviously.

Does this happen to others?

I've experienced this a couple times... No matter where I went, I heard the sound of an M2 machine gun constantly reloading in the background, like if it was just behind me. I'm pretty sure it's related to this issue, but with the simulation manager disabling armed Offroads, while they emit sounds even with no passenger: http://feedback.arma3.com/view.php?id=17398

That issue sounds similar. The sounds in my case are not just behind me, they're always directional somewhere - sometimes in front and you can only just hear them, sometimes left/right/wherever and close, etc.

I find this happens when missions start running that have base parts. I haven't noticed this happening on missions that don't, but, I haven't kept an eye out much - I will do so thought and report back.

This also happens randomly, I assume as the mission spawns in new objects (I think just base parts?) in towns.

It happens for ~20s after starting the mission as new objects (again, I think just base parts?) go through their initial spawn in.

Vehicle spawning, actually. Indeed, the direction of the sound changes from time to time, but once the sound starts playing, it seems frozen into place, even if you move away or turn the camera around.

That's odd, because I'm sure I've noticed it happening in outpost missions.

I'll keep an eye out some more.

Or maybe it's a basepart... I don't know if's the armed offroad, but it did play with one of those close to me; Another guess would be the stop-sign boom barrier, but I'm not sure.

[AgentRev]

Nevermind, it's not the boom barrier.

I concur, it is the armed offroad; if you go in the editor and place one with the following init and stay close to it, it's gonna make the exact same sound after about 10 sec:

this removeMagazines "100Rnd_127x99_mag_Tracer_Yellow";
this addMagazine "100Rnd_127x99_mag_Tracer_Yellow";
reload this;

I guess we hear the sounds louder online because the reloading is done on the server and the sound is broadcast over the network, but when it arrives on the client, the offroad has simulation disabled, which confuses the engine and produces what we hear.

It's possible to hear them at random times, because armed offroads do respawn, and their magazine loadout is changed every time.
