No sound in Arch Linux with KDE

I recently bought a laptop and installed ArchLinux on it. Sometimes it starts with sound but not all times. Sometimes I have just a Dummy Output in devices, sometimes nothing and even if the real device is listed it doesn't work all times.

I also noticed sometimes that the headphone isn't detected when plugged or that they are always detected even when they are not plugged The output of sudo aplay -l

Neither aplay -vv somefile.wav nor speaker-test -Dplug:surround51 -c6 -twav works. They execute without error but no sound.

The link I got from executinghttp://www.alsa-project.org/alsa-info.sh is http://alsa-project.org/db/?f=e1b3e20d3afdec252ba77d465ac79d9eac3ea9a6

I also tried to reinstall pulseaudio completely without success and installing oss without any change.
