Who are the people who are drinking/smoking/being loud? If it's your brother, could your husband intervene on your behalf since you're still so early in sobriety? If it's your husband, then yes I would think a conversation is in order if you can't even have peace with earplugs in...
If you think it'll lead to an argument maybe you could even just negotiate a short window, to be revisited later. No loud music or smoke during the first two weeks, and at that point you can discuss house conduct moving forward?
