Headphones are still not working

[torgeir-01]

I own an Acer Aspire 1-533 and have run into a problem. My computer notices my headphones, bacause it says in HD-Audio that there are analog speakers attached. My headphones are not displayed as a separate set of speakers. Audio in the built in speakers work, the AUX is functional, the headphones are funtional, yet there is no sound. Any help would be appreciated.

I have checked so that all volume configurations are correct, yet they do not work.
