Just happened to me in a keystone, so it’s not just raid bosses.
Edit: if I uncheck the box, recheck the box, and restart the client (I have to restart; can’t just disable/enable) it works again, briefly, and then immediately breaks. I’ve done it between each dungeon and it breaks again in the next one.
Turns out I rely a lot on audio cues from bosses because this suuucks.
Same issue. I noticed I wasn’t getting Raz’ Thundering dialog during a CoS M+ run. Then I noticed that NO dialog was happening. My settings have dialog enabled but it just quit working out of nowhere.
Make sure its the “Dialogue” toggle you’re turning on and off, not just turning it down to 0% and back up to 100%. It should fix it, but its temporarily and it could break again. I’ve had it break a couple times almost back to back (tested on an NPC when I came back in, then had it break shortly into the next dungeon for example)
Not sure if this will help those experiencing the issue, but there was a change made by Blizzard in the most recent patch to allow addons to write cache data to the Config.wtf
The problem is that if an addon writes more than 1103 characters to the config, it starts to affect the formatting of SET variables, such that they start overwriting cvars. This could be happening to SET Sound_DialogVolume
Try disabling addons, re-enable dialogue, restart the game and it see if that works.
Details Damage Meter in specific has been causing issues for me.
If it’s the cause of your issue, then yes it will.
As Details is the only addon that I have found so far that causes this underlying Blizzard code issue to occur, you could try disabling just this addon. I have already been in contact with the author who is aware of the problem and is looking to implement a work-around on their end, even though this is a problem with the way data is written to the config.wtf file by addons.
I just came here to ask about this. I noticed that the final boss of Court of Stars, God King Skovald, Odyn, etc. have not had audible dialogue all of 10.0.7.
Thanks, I’ll try disabling it, cause this has been driving me crazy.
