Describe the bug
Turned off all sounds. Got same error message in chatlog many times.
Was running DBM for the first time, in Gnomeregan 5-man dungeon.

Do you have an error log of what happened?
Here is the first line of the error, I don't have the rest:
"Playsoundfile failed do to missing media at." Yes, with bad English.

Did you try having DeadlyBossMods as the only enabled addon and everything else (especially something like ElvUI) disabled?
No.

Which version of DeadlyBossMods are you using?
Downloaded it today.

Was it working in a previous version? If yes, which was the last good one?
I don't think I have run the mod with sounds turned off before.

After I started WoW again:

This is already fixed in next version, I've just had trouble finishing up a few things and tagging a new release because I keep losing power when trying to work on things. I hope to finish things up tonight and get release out so this issue doesn't affect users when new content starts.
