When resting I noticed that every few days I'll hear a clothes equipping sound, my assumption is that a mod is doing it but I'm not 100% sure, does anyone have an idea what it could be?

I'll upload my load order later

I experienced that too, but I always though that was the sound of an enchanted item recharging to full.

Maybe it's just the sound of you putting your hands in your pockets?

Pretty sure Miniamir nailed that one. I was puzzled by it myself for a long time: the sudden sound of a weapon being drawn when there were no enemies around, other odd noises at peculiar moments, etc. Ended up that all were related to enchanted items reaching a full charge.

Always thought it was a game glitch... but, the different sounds for different item types makes sense.
