и закидываешь его по адресу (для примера) ...\cstrike\cfg\mani_admin_plugin

Сами звуковые мр3-файлы должны лежать в папке по адресу ...\cstrike\sound\quake.

Далее в папке ...\cstrike\cfg нужно создать файл mani_quake_sounds.cfg следующего содержания:

mani_quake_sounds 1
mani_quake_kill_streak_mode 0
mani_quake_humiliation_mode 1
mani_quake_firstblood_mode 1
mani_quake_firstblood_reset_per_round 1
mani_quake_headshot_mode 3
mani_quake_prepare_to_fight_mode 1
mani_quake_multi_kill_mode 1
mani_quake_dominating_mode 3
mani_quake_dominating_trigger_count 4
mani_quake_rampage_mode 1
mani_quake_rampage_trigger_count 6
mani_quake_killing_spree_mode 3
mani_quake_killing_spree_trigger_count 8
mani_quake_monster_kill_mode 3
mani_quake_monster_kill_trigger_count 10
mani_quake_unstoppable_mode 1
mani_quake_unstoppable_trigger_count 12
mani_quake_ultra_kill_mode 1
mani_quake_ultra_kill_trigger_count 14
mani_quake_god_like_mode 1
mani_quake_god_like_trigger_count 16
mani_quake_wicked_sick_mode 1
mani_quake_wicked_sick_trigger_count 18
mani_quake_ludicrous_kill_mode 1
mani_quake_ludicrous_kill_trigger_count 20
mani_quake_holy_shit_mode 1
mani_quake_holy_shit_trigger_count 24
mani_player_settings_quake 1
mani_quake_auto_download 1

И последнее – нужно в файле autoexec.cfg лежащего по адресу ...\cstrike\cfg добавить строчку:

exec mani_quake_sounds.cfg - это финальный шаг.
