Looks like another question. How do I add a sound signal about the start of an event that notifies 5 minutes before the start of the event?

local addonName, addon = ...
local Backdrop = {
    bgFile = "Interface\\DialogFrame\\UI-DialogBox-Background",
}
 
local frame_x = 0     
local frame_y = -200    
f = CreateFrame("Button", "ZAMROTimer", UIParent, "BackdropTemplate")
f:SetWidth(255)                                          
f:SetHeight(30)
f:SetBackdrop(Backdrop)
f.text = f:CreateFontString(nil,"OVERLAY","GameTooltipText")
f.text:SetTextHeight(15)
f.text:SetPoint("CENTER")
f:SetClampedToScreen(true)
f:SetPoint("CENTER",UIParent,"CENTER",frame_x,frame_y)
f:EnableMouse(true)
f:SetMovable(true)
f:RegisterForDrag("LeftButton")
f:RegisterForClicks("AnyUp")
f:Show()
f:RegisterEvent("PLAYER_ENTERING_WORLD")
f:SetScript("OnDragStart",function(this) 
    this:StartMoving()
end)
f:SetScript("OnDragStop",function(this)  
    this:StopMovingOrSizing()
    frame_x,frame_y = this:GetCenter()
    frame_x = frame_x - GetScreenWidth() / 2
    frame_y = frame_y - GetScreenHeight() / 2
    this:ClearAllPoints()
    this:SetPoint("CENTER",UIParent,"CENTER",frame_x,frame_y)
end)
 
local Localizations = {
    enUS = {
        Waiting = "|c1C7BCEFFCommunity Feast:\nbefore the start: %s|r",
        Running = "|cFF35BE21Community Feast:\n%s until completion|r",
    },
    deDE = {
        Waiting = "|c1C7BCEFFGemeinschaftliches Festmahl:\nNächste Veranstaltung ist in: %s|r",
        Running = "|cFF35BE21Gemeinschaftliches Festmahl:\n%s bis zum Ende der Veranstaltung|r",
    },
}
 
local locale = GetLocale()
local L = Localizations[locale] or Localizations.enUS -- Default to enUS if locale doesn't exist in the table
 
local function printTime(timetotrun, inevent)
    local hideSeconds = timetotrun >= 120
    local msg = L.Waiting
    if inevent then
        msg = L.Running
    end
    f.text:SetText(format(msg, SecondsToTime(timetotrun, hideSeconds)))
end
 
 
regionEventStartTime = {
    [1] = { -- eu
        starttime = 1670331660,
        eventDuration = 900,
        eventIntervalInSeconds = 5400,
        enable = true,
        datablock = {}
    },
}
local inEvent, timeToRun
local eventTime = regionEventStartTime[1].eventDuration -- Time the event runs in seconds(15 mins)
local waitTime = regionEventStartTime[1].eventIntervalInSeconds -- Time between events in seconds (90 mins)
local startTime = regionEventStartTime[1].starttime -- Start time from the table
local serverTime = GetServerTime()
local timeToEvent = (startTime - serverTime) % waitTime -- Remaining time before next event starts
 
if timeToEvent > (waitTime - eventTime) then -- Is there between 1:15 and 1:30 to go? If so, we're in the event
    inEvent = true
    timeToRun = eventTime - (waitTime - timeToEvent)
else                    -- Otherwise, set the ticker timer to time to next event
    inEvent = false
    timeToRun = timeToEvent
end
local ticker = C_Timer.NewTicker(1, function() 
    if timeToRun > 0 then
        timeToRun = timeToRun - 1
        printTime(timeToRun, inEvent)
        return
    end
    if inEvent then -- The event just finished
        inEvent = false
        timeToRun = waitTime - eventTime -- Reset ticker timer to 90 minutes wait time minus 15 mins event time
    else  -- Waiting for the next event just expired
        inEvent = true
        timeToRun = eventTime -- And the event is running
    end
    printTime(timeToRun, inEvent)
end)
printTime(timeToRun, inEvent)

I've written the code here (but it doesn't seem to be quite right)

local showedTime = startTime and timeToEvent or waitTime
        
        if showedTime < 3600 then
            self.timer:SetText(date("%M:%S", showedTime))
        else
            self.timer:SetText(date("%H", showedTime)-1 .. date("h%M", showedTime))
        end
 
if not startTime then
            if showedTime < 300 then
                if not self.soundPlayed then
                    PlaySound(32585, "Master")
                    self.glow:SetVertexColor(0, 1, 0)
                    self.soundPlayed = true
                end
            elseif self.soundPlayed then
                self.glow:SetVertexColor(0, 0, 0)
                self.soundPlayed = false
            end
        end
