Drywall water damage - replace?

[Bear28]

Hi,

My friend who knows zip about home theatre, etc recently had a bit of a flood thru his ceiling. When he moved in there were pre-existing speaker hookups run thru the ceiling for his back speakers. While the water damage isn't right above where these hookups are, he is worried about his speaker performance and stuff and if he will need to replace the drywall, etc.

I told him to just let it dry, rent those blowers/dehumidifiers from Home Depot and have them run for a day or two, and that it will be fine as it wasn't a big amount of damage or anything. Am I wrong? Would the speaker wire run be affected at all?

Thanks
