"Sound XZ is missing" alert

[Tonyleila]

Hey, I'm currently working much with my AddOn Sound Pack. It adds many new sounds to your Shared Media Library.

Now I woud like to have a chat print warning or something like this if I registered a sound file wong. Currently the file is showing up but there is no error it just won't play. Woud make it much more easy than to test all 350 files ingame.

http://wow.gamepedia.com/API_PlaySoundFile

There does not appear to be a bad error if the file is missing - it just won't play. There is a return status, which is 1 if the sound was OK and nil if it couldn't be found.

Current code:

local LSM = LibStub("LibSharedMedia-3.0")
LSM:Register("sound", "SoundPack: Alarm_01", [[Interface\Addons\SoundPack\01_Alarms+Bells\Alarm_01.ogg]])

local LSM3 = LibStub("LibSharedMedia-3.0", true)
local LSM2 = LibStub("LibSharedMedia-2.0", true)
local SML = LibStub("SharedMedia-1.0", true)
 
SoundPack = {}
SoundPack.revision = tonumber(string.sub("$Revision$", 12, -3)) or 1
 
function SoundPack:Register(mediatype, key, data, langmask)
    if LSM3 then
        LSM3:Register(mediatype, key, data, langmask)
    end
    if LSM2 then
        LSM2:Register(mediatype, key, data)
    end
    if SML then
        SML:Register(mediatype, key, data)
    end
    if not SoundPack.registry[mediatype] then
        SoundPack.registry[mediatype] = {}
    end
    table.insert(SoundPack.registry[mediatype], { key, data, langmask})
end
 
function SoundPack.OnEvent(this, event, ...)
    if not LSM3 then
        LSM3 = LibStub("LibSharedMedia-3.0", true)
        if LSM3 then
            for m,t in pairs(SoundPack.registry) do
                for _,v in ipairs(t) do
                    LSM3:Register(m, v[1], v[2], v[3])
                end
            end
        end
    end
    if not LSM2 then
        LSM2 = LibStub("LibSharedMedia-2.0", true)
        if LSM2 then
            for m,t in pairs(SoundPack.registry) do
                for _,v in ipairs(t) do
                    LSM2:Register(m, v[1], v[2])
                end
            end
        end
    end
    if not SML then
        SML = LibStub("SharedMedia-1.0", true)
        if SML then
            for m,t in pairs(SoundPack.registry) do
                for _,v in ipairs(t) do
                    SML:Register(m, v[1], v[2])
                end
            end
        end
    end
end
 
SoundPack.frame = CreateFrame("Frame")
SoundPack.frame:SetScript("OnEvent", SoundPack.OnEvent)
SoundPack.frame:RegisterEvent("ADDON_LOADED")

Well, as far as I know the only way to "test" a sound in-game is to play it. If you wanted to do it automatically without audibly playing the sound, I'd try setting the "Ambience" sound volume to 0, playing the sound on the "Ambienc" channel and checking the return value, then restoring the "Ambience" volume to whatever it was before. You might need to use a slightly higher value than 0, but I'd try 0 first.

However, I'm pretty sure there's also a limit on the number of sounds that can be playing at once, so you'd also need to implement some kind of queue. It's probably not worth the effort, especially since there would be interference with other addons and/or the default UI playing sounds during the test. I'd suggest partly or completely automating the process (see the MyMedia instructions in SharedMedia) so you can't screw it up by typing a file name wrong.

Also, LibSharedMedia-2.0 has been deprecated for years (it uses Ace2, which was discontinued with the launch of WotLK, so it probably doesn't even work anymore) and there never was any such thing as LibSharedMedia-1.0 (the predecessor to 2.0 was called SurfaceLib, and won't work anymore either) so you can clean up your code quite a bit by removing those. There's also no point in delaying the registration of media. Just load LibSharedMedia-3.0 (typically embedded in your addon) and then register your media directly:

## Interface: 60000
## Title: Sound Pack
## OptionalDeps: LibSharedMedia-3.0

Libs\LibStub\LibStub.lua
Libs\CallbackHandler-1.0\CallbackHandler-1.0.lua
Libs\LibSharedMedia-3.0\LibSharedMedia-3.0.lua

SoundPack.lua

local ADDON = ...
local PATH = "Interface\\AddOns\\"..ADDON.."\\SoundFiles\\"
local M = LibStub("LibSharedMedia-3.0")

M:Register(TYPE, "A Sound",       PATH.."filename_a.ogg")
M:Register(TYPE, "Another Sound", PATH.."filename_b.ogg")
M:Register(TYPE, "Weird Sound",   PATH.."weird.ogg")
-- more sounds here

That's all you need.

Edit:
Actually it looks like you're already doing this, based on the first code you posted. I don't know what that second block is for, and it should be throwing an error anyway; you can just get rid of it.

I see thank you! Do I realy need CallbackHandler-1.0.lua and LibSharedMedia-3.0.lua inside my libs folder? Because currently its working without

If you want your addon to work no matter what other addons someone is using, yes, and LibStub too. Otherwise you're depending on some other addon to load them first, but without setting a hard dependency on some specific addon (bad because your addon doesn't actually depend on another addon) or writing more code to delay everything until some other addon loads the libraries, you can't guarantee that things will happen in the right order. While you can delay for some other addon, it's better practice just to have your addon include all the things it needs.

You could use StopSound with the sound handle returned by PlaySoundFile to stop the file immediately after playing it during the testing phase.
