Context
Whilst testing mods for my modpack I replaced my arms within the cyber surgeon and had the equipping sound constantly playing. I decide to test this within and environment without other mods and found that it was caused by this

Expected behavior
Items held should be dropped in survival and ignored in creative without arms
Cyber arms should do the same as well while not powered
Actual behavior
Whenever holding an item (none or cyber arms) in creative the sound plays in inventories or the cybersurgeon (powered arms yielded the same results as unpowered)
In survival holding an item (cyber arms) the same happens

Steps to reproduce

1. Turn up the Players sounds
2. Remove Arms (Add cyberarms to test in survival)
3. Hold any item in your hotbar
4. Open your inventory or the cybersurgeon
5. Let your ears bleed with the equipping sound

Your environment
Version used: cyberware-1.12.2-0.2.10.19
Operating system: Windows 10 64-bit

Already fixed in dev. You can disable the custom render for now.
