No sound from internal speaker [SOLVED]

The problem I have is that I only get sound from headphones plugged-in. When plug-off the headphones I get no sound from the laptop internal speakers. I have Arch installed for over a year now I only have this problem for a month now. I have search the Internet and tried tons of thing but none worked so far. I have read that the headphone jacket has a mechanical sensor which detects whether there is a headphone plugged or not and that this could be broken. Is there any way to test this without opening the laptop??
On the software side I know udev detects the sound car as:

[netlak@soulrebel ~]$ lsmod|grep '^snd' | column -t
snd_hda_codec_hdmi  24121  1
snd_hda_codec_idt   56637  1
snd_hda_intel       23311  2
snd_hda_codec       89032  3   snd_hda_codec_hdmi,snd_hda_codec_idt,snd_hda_intel
snd_hwdep           6389   1   snd_hda_codec
snd_pcm             74780  3   snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec
snd_timer           19544  1   snd_pcm
snd                 59214  11  snd_hda_codec_hdmi,snd_hda_codec_idt,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_timer
snd_page_alloc      7153   2   snd_hda_intel,snd_pcm

and

[netlak@soulrebel ~]$ cat /proc/asound/modules
 0 snd_hda_intel
 1 snd_hda_intel

Of course I'm sure nothing is muted.
I will appreciate any help!!!
Thanks in advance, jose.

Hmm, I had this exact issue today after update and it turned out the speakers got muted in Pulseaudio, in Output Devices tab. Just in case you missed it. If not, it's probably something else.

Re: No sound from internal speaker [SOLVED]

Well. Thanks z0id, I think I got the problem. I booted with a Ubuntu live CD and got the exact same problem. I think this clearly says that it's a hardware problem.
Will mark the post as solved and take the pc to repair to see what they say!!
Thanks, jose.
