Hi, would it be possible to add a blacklist for mmorpg:dungeon?

I understand this issue was raised before for other dims. Would it be possible to make the list configurable? I guess currently, you need to add these dimensions to your config manually for us to enable/disable.

Yes you can. Use the command /cmdclientconfig. There is a option silent dimension, add yours there and it should disable all sounds in that dimension.

Just to clarify this won't disable ALL sounds but only the ambient sound sounds right?

Yes, only sounds from ambientsounds.
