I did search prior to post. Please pardon me if the solution was in front of my nose.
On my system, Mint 13 Cinnamon 64 bit, I have sound from the onboard soundcard at th eback, but no sound from the front panel, as the title of this thread says. Funny thing is that if I insert the headphones in the front panel the speakers go mute as they should, but also the headphones remain mute. In Windows 7 and 8 everything works, so the hardware failure is to be excluded.
I paste here some details, I guess that they may be useful...

hardware tab, profile from the dropdown menu Analog stereo duplex (I tried all of the right sunding ones anyway, either don't work at all, or give the same result)
output tab, connector from the dropdown menu is Analog output
I tried to install ALSA a while back because Skype audio wouldn't work at all, but now it comes out that the sound in Skype is still managed by PulseAudio volume control.
Although I tampered the system, the front panel really never worked, so I don't consider myself guilty...
Would some kind soul please try to explain what's wrong? It would be highly appreciated.
Thanks, thanks thanks!
