No

This monitor does not have integrated speakers. Integrated speakers often have poor quality, I would recommend getting external PC speakers: https://www.digitec.ch/de/s1/producttype/pc-lautsprecher-78

Hello, He has both. Greetings J.

No, the screen came with a CH plug and has worked perfectly ever since 👍

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. Dell AE515M
