AlliedModders - [ANY] PrecacheSound not working properly.

PHP Code:

		
			
public OnMapStart(){

AddFileToDownloadsTable("sound/asdf/c1.wav");

  AddFileToDownloadsTable("sound/asdf/c2.wav");

  AddFileToDownloadsTable("sound/asdf/c3.wav");

  AddFileToDownloadsTable("sound/asdf/c4.wav");

  AddFileToDownloadsTable("sound/asdf/c5.wav");

  AddFileToDownloadsTable("sound/asdf/c6.wav");

  AddFileToDownloadsTable("sound/asdf/c7.wav");

  AddFileToDownloadsTable("sound/asdf/c8.wav");

  AddFileToDownloadsTable("sound/asdf/c9.wav");

   AddFileToDownloadsTable("sound/asdf/c10.wav");

    AddFileToDownloadsTable("sound/asdf/c11.wav");

    AddFileToDownloadsTable("sound/asdf/c12.wav");

    AddFileToDownloadsTable("sound/asdf/c22.wav");    

    AddFileToDownloadsTable("sound/asdf/c23.wav");

    AddFileToDownloadsTable("sound/asdf/c24.wav");

    AddFileToDownloadsTable("materials/asdf/c1.vtf");

    AddFileToDownloadsTable("materials/asdf/c1.vmt");

    AddFileToDownloadsTable("materials/asdf/c2.vtf");

    AddFileToDownloadsTable("materials/asdf/c2.vmt");

    AddFileToDownloadsTable("materials/asdf/c3.vtf");

    AddFileToDownloadsTable("materials/asdf/c3.vmt");

    AddFileToDownloadsTable("materials/asdf/c4.vtf");

    AddFileToDownloadsTable("materials/asdf/c4.vmt");

    

    PrecacheSound("/asdf/c1.wav");

    PrecacheSound("/asdf/c2.wav");

    PrecacheSound("/asdf/c8.wav");

    PrecacheSound("/asdf/c9.wav");

    PrecacheSound("/asdf/c10.wav");

    PrecacheSound("/asdf/c11.wav");

    PrecacheSound("/asdf/c12.wav");

    PrecacheSound("/asdf/c13.wav");

    PrecacheSound("/asdf/c14.wav");

    PrecacheSound("/asdf/c15.wav");

    PrecacheSound("/asdf/c16.wav");

    PrecacheSound("/asdf/c17.wav");

    PrecacheSound("/asdf/c18.wav");

    PrecacheSound("/asdf/c19.wav");

    PrecacheSound("/asdf/c20.wav");

    PrecacheSound("/asdf/c21.wav");    

    PrecacheSound("/asdf/c22.wav");    

    PrecacheSound("/asdf/c23.wav");

    PrecacheSound("/asdf/c24.wav");

}
It works fine when I first put the plugin in, but after changing the map it outputs SV_StartSound: not precached (0).

I wonder what could be the cause.
