Problem to my custom rom for lg g pro lite

My rom can not read the ringtones ( messages / calls / alarms) , I discovered that the Rom the Law of (storage / emulated / 0) and 0 then inside there are various ringtones / alarms etc folders.
So I decided to create a folder that then during the installation of the Rom in the recovery I put it on 0 folder, but do not check me anything !!!! what do I have to do??? Now I put my update- script.... P.S (Sorry for my bad english)

ui_print("Mount System");
run_program("/sbin/busybox", "mount", "/system");
ui_print("Mount Storage");
run_program("/sbin/busybox", "mount", "/storage");
ui_print("Estract System");
package_extract_dir("system", "/system");
ui_print("Estract Audio Files");
package_extract_dir("audio", "/storage/emulated/0");
ui_print("Im finish to install rom");
