Description:

Hello. I'm not quite sure when it started to happen but I can hear rain sounds and footsteps, stuff like that okay. But there was no ambience. Everything was quiet. When I was flying over the world, i could hear the wave and bird sounds that should be present when down on the ground. It's like the ambience sounds have been reversed. (Not hearable closely, but hearable further away).

Any ideas?

Main mods I was using was Terrarium (earth generation)
Optifine
Sildur's Shaders
Realistic Road Mod
Traffic Control
World Edit
B3M (Time-scale)
Better Builders Wands
Instant Massive Structures
MoarSigns
OreLib
RailsOfWar

I don't think it has anything to do with the amount of mods, since it has worked well with similar amounts of mods. It may be one of the mods (new mods added were Terrarium, B3M)

Thank you!!

It seems like it might be terrarium that is causing the problem, as when I went on a normal generated world, the sounds worked fine. Yet, when I made another 'Earth' replica world it wasn't working properly. But, I don't see why this would be causing a problem. If you watch this video (How to turn Minecraft into a Real Life Simulator). He combined terrarium with Dynamic Surroundings mod and it worked fine for him. My graphics card is a NVIDIA GeForce GTX 750 Ti.

I think I manged to fix the problem. It was terrarium that was causing it. I managed to keep terrarium though by setting the world generation preset to the one meant for survival, but I still managed to play in creative mode. No worries, I'm not using terrarium right now but Dynamic Surroundings makes Minecraft more realistic and relaxing.
