Make sure you haven't restricted the functions you want to use for the admins, here's what they are:
// ADDING FLAGS MEANS YOUR ARE STOPPING ADMINS FROM USING
// THOSE OPTIONS UNLESS YOU HAVE mani_reverse_admin_flags set to 1
// in your autoexec.cfg
//
// Restriction options are :-
//
// k = restrict admin from kicking players
// r = restrict admin from executing rcon commands via ma_rcon
// q = restrict admin from executing rcon commands from the menu
// e = restrict admin from the adminexplode command
// m = restrict admin from slaying players
// b = restrict admin from banning players
// s = restrict admin from running ma_say
// o = restrict admin from running ma_chat
// a = restrict admin from running ma_psay
// c = restrict admin from changing maps
// p = restrict admin from playing sounds
// w = restrict admin from restricting weapons
// z = restrict admin from plug-in config menu
// x = restrict admin from running admincexec commands
// y = restrict admin from running admincexec from the menu
// i = restrict admin from running blind commands
// l = restrict admin from running slap commands
// f = restrict admin from running freeze commands
// t = restrict admin from running teleport commands
// d = restrict admin from running drug commands
// g = restrict admin from running ma_teamswap and ma_balance commands

//
// STEAM_0:0:2388333 rp // Admin can't rcon and play sound !!
//
// Another example
