Wall hit/use sound replacement?

[adelpha]

First of all, I love this port. It's awesome, and I can't imagine playing BS without it.

This isn't an issue, more of a general question but I didn't know where to ask.

I know you can turn off the wallhit sound in the switches, but that doesn't help with intentional use of the Interact key/button.

I'm running around wallbanging with the Interaction key to find secret areas and the constant noise is driving me mad. Is there a way of replacing the wall hit/failed interaction sound with something less awful?

I see several options:

• Toggle that sound like the wallhit one.
• Use external audio files like it's done in external textures.

External audio sounds like a good solution if it's easy enough to implement.
