If a quest requires sound, can we have a warning before we accept the quest, please? It's frustrating to accept a quest and suddenly find out I need to quit out after having done so. Personally, I play on two different computers, one of which is much easier to see and use, but it has no speakers hooked up to it. I cannot just turn sound on. The other is much more annoying to use, but can do sound, so I will switch computers to do the quest, but it'd be nice to have known not to accept the quest in the first place when I could not do it. And for people who are deaf and will not be able to make use of the sound data, it'd be nice for them to know in advance that this quest is not accessible. Or for people who sometimes can have their computer make noise, but sometimes need it to be quiet and may not have earphones handy, it'd be good for them to know to do the quest later, when they won't disturb anyone else.
I expect this won't be an issue for most players, but I expect it'll affect some people beyond just me, and it doesn't seem that hard to put the info into the quest dialogue before you click to do the quest now.
