I have a problem with my sound driver or the software managing my sound output device. Strangely sometimes it is working, and sometimes it doesn't work and then I just can't get it working propperly again. This is what happens: the software doesn't detect my headphone from being plugged in, initially no output device produces any sound. However after changing INput device, the integrated speaker on my laptop is able to produce sound.
The goal of course is to be able to output sound over the device plugged in at the headphone jack.
Here is some extra information.

Sorry couldn't stop typing, now i will describe a small use case what happen before this problem started when the driver was still working probably.
- Boot with headphone jack plugged in.
- Removed headphone cable from headphone jack.
- Plugged in another headphone jack cable (5.1 surround system).
- Ubuntu asks what device is plugged in (this doesn't happen anymore as well).
- I selected headphones, since there is no specific option for surround.
- Removed surround system cable from headphone jack.
- Plugged in the headphone cable.
- Pressed cancel where ubuntu asks to select the type of output device.
No unusual things where happing before I booted up again.
