I noticed a sizzling sound first when I entered Angeline's Aromatics in Solitude, still does it every time.
But now I also hear the sizzle (or "fizzle") when I enter Honeyside or load a game saved there.
Does anybody know what this might indicate? Any ideas? I'm just curious, I wonder what it means.

Happens to me in Breezehome, because of the enchanted weapons on display. That might be the cause. It's a little bug.

I have that, too. I thought it was a suddenly properly playing effect of a potion, that just keeps restarting, or something.
