The mobo comes with a standard 8ch integrated solution for your sound. I would suggest you get something better but for all practical purposes it's acceptable.
I also recommend you get a better cooler for your CPU than the default one. The design of the Ivy Bridge series uses a different paste, and thus led to somewhat significantly higher readings for temperatures. The Xigmatek Loki or Cooler Master's Hyper 212/+ is there if you want budget options.
