Presence of sound physics significantly increases the volume of UI sounds

[deli73]

When the mod is installed, the menu clicks and seemingly any other UI-related sounds appear to increase.

Steps to reproduce:

1. Observe the volume of the menu clicks without the mod installed.
2. Install the mod, observe the increased volume of the menu clicks.

This is especially an issue because the other sounds in the game actually get quieter by comparison, due to the way the mod works. This makes it impossible to lower the menu clicks to regular volume without making othe rest of the game near-inaudible. There doesn't seem to be a config option for menu sounds, either, and they're on the master channel.
