Triggering sound after countdown.

[Kajuvra]

So ive created an addon that will trigger a sound file at the start of a race but the player aka racers who have the addon aren't hearing the sound file being played and i dunno why. any help would be greatly appreciated

GnomeRunner.soundFile = "Interface\\AddOns\\GnomeRunner\\Sounds\\GnomeMaleCharge03.ogg"

-- Function to trigger the sound for race start
GnomeRunner.PlayRaceStartSound = function()
    if IsInRaid() and UnitIsGroupLeader("player") then
        PlaySoundFile(GnomeRunner.soundFile)
        C_ChatInfo.SendAddonMessage(GnomeRunner.addonPrefix, "START_RACE_SOUND", "RAID")
    end
end

-- Inside the StartRace function
function GnomeRunner.StartRace()
    print("StartRace function called")

    if not GnomeRunner.raceInProgress then
        GnomeRunner.raceInProgress = true
        GnomeRunner.raceStartTime = GetServerTime()
        GnomeRunner.totalDeaths = 0
        GnomeRunner.totalRacers = 0
        GnomeRunner.totalGoldDistributed = 0

        local countdown = GnomeRunner.countdownSeconds
        local countTimer

        local DisplayCountdown = function(count)
            if count > 0 then
                SendChatMessage(count, "RAID_WARNING")
            else
                SendChatMessage("GO GO GO! " .. GnomeRunner.raceName .. " has just begun!", "RAID_WARNING")
                print("Sending addon message: START_RACE")  -- Add this line for debugging
                GnomeRunner.PlayRaceStartSound()  -- Trigger the sound here
            end
        end

        countTimer = C_Timer.NewTicker(1, function()
            if countdown == GnomeRunner.countdownSeconds then
                SendChatMessage("The Race: " .. GnomeRunner.raceName .. " is starting!", "RAID_WARNING")
            end

            DisplayCountdown(countdown)

            countdown = countdown - 1
            if countdown < 0 then
                countTimer:Cancel()
                GnomeRunner.frame:SetScript("OnUpdate", function(_, elapsed)
                    GnomeRunner.OnUpdate(elapsed)
                end)
            end
        end)
    else
        print("Race already in progress.")
    end
end

The Part of the code to recieve the message and play the sound.

function GnomeRunner.OnChatMsgAddon(prefix, message, channel, sender)
    if prefix == GnomeRunner.addonPrefix then
        print("Addon message received:", message)

        if message == "START_RACE" then
            print("Received START_RACE. Playing sound.")
            PlaySoundFile(GnomeRunner.soundFile)
        elseif message == "START_RACE_SOUND" then
            PlaySoundFile(GnomeRunner.soundFile)
        end
    end
end

Have you registered your addon chat messages to be received using C_ChatInfo.RegisterAddonMessagePrefix()?
This tells the Blizzard chat servers that you're available to receive messages marked with your addon message prefix.
