HaloMods "Classic" Read-only Archive

For my recent mod, i wanted the ambient swamp sounds from 343 GS.
Ifound what i needed, put them in, but how do i swap it for the birds?

I tried [ssce] and changing the lsnd there, but it still is the birds. Any ideas?

For what level is this?
Just open up the existing [lsnd] tag and swap the sound depedencies.
