No, there aren't any, but it's relatively easy to attach an external speaker from Dell to the base with Velcro straps, which makes everything sound a bit better than without. The Dell speaker sounds very good for the money and has a thinner spot in the middle so that it doesn't stick out so much behind the panel. I've been using a solution like this for a long time with my display, which has internal speakers that sound pretty lousy.
