Ok, I saw another thing in your alsa-info, it seems like the speaker pin
is not powered up:
Node 0x1f [Pin Complex] wcaps 0x400501: Stereo
Pincap 0x00000010: OUT
Pin Default 0x90170110: [Fixed] Speaker at Int N/A
Conn = Analog, Color = Unknown
DefAssociation = 0x1, Sequence = 0x0
Misc = NO_PRESENCE
Pin-ctls: 0x40: OUT
Power states: D0 D1 D2 D3 D3cold
Power: setting=D3, actual=D3
Connection: 2
0x10* 0x11
Could you please try the following: download and install snd-hda-tools from
ppa:diwic/ppa (this is for natty). Then run this terminal command:
sudo hda-verb /dev/snd/hwC0D0 0x1f SET_POWER_STATE 0
And see if that helps to get sound out of internal speakers (you mean
*internal* speakers, right?).
