Some messages missing

[gi2k15]

A couple of days after 4.2 was alive, an addon started blocking a lot of annoucements, like some yells from bosses, the horn warnings from Shannox, some warnings during the boss fights and so on. But I really can't find the source of it! Can someone give me an idea of which addon may be causing it? I went to chat settings and every filter is turned on, so I guess it's not a configuration.

Thank you!

Hi there. I've had the same problem too. It happens randomly and even with all addons disabled, so I think it's a bug in patch 4.2.

Would be nice if someone else could confirm this, too.

[Verttex]

With the arrival of 4.0 many sounds changed and I think the way sounds are executed was updated. Correct me if I am wrong.

[SDPhantom]

There was a glitch in Cata Beta with the sound system when multiple sounds were playing at once. Sounds would get out of sync and then stop for a while. Later, it would run through the entire sound queue at once when nothing was happening. They supposedly fixed that in the official 4.0.6 release. I know that was a long time ago, but it could have resurfaced. Some glitches do.

I haven't had it come up yet in the official client, but that might explain it.

[Haleth]

I'm quite certain the OP isn't talking about sound, but chat messages, namely boss yells and boss ability warnings (the ones that produce a link to the ability used).

[SDPhantom]

If it's chat, you could try making a temporary addon to check if the related events are even firing. My first guess would be to watch for the following events.

CHAT_MSG_MONSTER_EMOTE
CHAT_MSG_MONSTER_SAY
CHAT_MSG_MONSTER_WHISPER
CHAT_MSG_MONSTER_PARTY
CHAT_MSG_MONSTER_YELL
CHAT_MSG_RAID_BOSS_EMOTE
CHAT_MSG_RAID_BOSS_WHISPER

It may be a bit much, but this list should capture ANY chat message generated from an NPC.
This code would be an example of a way to debug these events.

local frame=CreateFrame("Frame");
frame:RegisterEvent("CHAT_MSG_MONSTER_EMOTE");
frame:RegisterEvent("CHAT_MSG_MONSTER_SAY");
frame:RegisterEvent("CHAT_MSG_MONSTER_WHISPER");
frame:RegisterEvent("CHAT_MSG_MONSTER_PARTY");
frame:RegisterEvent("CHAT_MSG_MONSTER_YELL");
frame:RegisterEvent("CHAT_MSG_RAID_BOSS_EMOTE");
frame:RegisterEvent("CHAT_MSG_RAID_BOSS_WHISPER");
frame:SetScript("OnEvent",function(self,event) print(event); end);
