See Enchantments SE Frost Sound Fix

Update: 

This might work for other similar mods that cause the same problem as people have reported.

After installing See Enchantments SE and playing for a while, I started to notice a hissing noise permanently getting stuck on my character.

Background:

Done some research, seems like this has been a bug ever since LE. Reload, restart, sexchange, none of it worked. Only way to get around this was to load a previous save where it did not happen (risk of it happening again), or removing the specific sound from the game (replacing with a empty .wav).

After digging around the original SeeEnchs.esp, seems like the issue is that Author redirected an actor cloak fx onto the weapon (which does look awesome), and the corresponding ambient sound has bad interactions with weapons sheath/unsheathe mechanics.

Solution:

So this is a very simple plugin that edits a single vanilla record:

Effect Shader: FrostFXShader

Ambient Sound: MAGCloakFrostLP > MAGEnchantedUnsheatheFrost

One "downside" of this approach is that any and all other frost cloak effects (being hit by frost spells/frost rune traps) will have less noticeable presence. But do note that other sources can cause the same exact bug, so it actually prevents those as well.

Load Order:

Load Order Should not matter for most people, doesn't even need to be below the SeeEnchs.esp. In my heavily modded 300+ plugins game, not a single .esp edits the same record. But if it doesn't work for you, try to put it lower.

Hope this helps.
