Hi
I just have a new computer and install Kubuntu 13.04 (32 bits) on it.
Everything is working except sound!
I have been looking around on similar topics and tried a lots of things but could not get a single sound from my laptop.
Please help!!!
Here is what I tried:

1) Alsamixer, sound is NOT muted
2) Use Phonon
3) Use Pulseaudio
4) The sound card seems detected (HDMI...)
5) I put the permissions to groups like audio, pulse, pulse-access

Through pulseaudio volume control, when I play a music (either through internet or amarok or xine...) the output table seems to detect the sound (the horizontal bar is moving) but I'm still not hearing anything!

Please help!
