On [Ask Ubuntu](https://www.askubuntu.com), it is especially common with Dell computers. I'm sending many people to this bug.

I have personally tested a pair of earbuds to make sure that sound could play through the headphone port, and that isn't a problem. The sound driver just refuses to recognize the existence of the speaker, even though the kernel does. I wouldn't be surprised if the last upstream update had something to do with it.
