Summary:                    No sound out of the built in speakers, but from
headphones on a Apple MacBook Pro
Description: 
Hi,

this error occours on all macbook pros! (see www.mactel-linux.org). Sound
comes only out of the headphones or out of line-out, but the internal
speakers keep mute. I cannot unmute them using the mixer (alsamixer,
kmix). I also tried a rc version of linux-2.6.17 with the same result.

I also tried to load the snd-hda-intel module with "model=laptop" and
"model=laptop-eapd".

Is the state got when HP jack is plugged or unplugged?
The node 0x0c looks like the built-in speaker pin, and it's configured as
input.  Usually, it's turned to be output when HP is unplugged.
