There are a few threads on the 3 series forum, just search the forum "no sound", and it seems like there is no 1 answer. Some had luck disconnecting the battery and and let the car reset. others pulled fuses. Some had their vehicles recoded, and some had their amplifiers replaced. Given the number of connections and amount of software involved in the Idrive system there are too many points of failure. On My brothers 335i, he had the same symptoms and had it replaced by BMW. I would start with checking fuses first and maybe resetting the car by disconnecting the battery for a few mins before going to a dealer.
