Macro low SD

[Navinter]

Hi i want to know if there is a way to make a macro that sound an alert when i have low sd's but without the alert sound, i want to hear another sound how i can when i place a protector (there u can choose from many sounds if u placed the file on the correct folder).

i'm using this macro:
1100 {Alert if item} itemID:=3155 min:=10 Misc.ItemCountEx(!itemID!)<!min! Misc.Alert(LOW ITEM)

But i dont know how to hear another sound than the default alert.

Thanks in advance.
