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".

I had the headphone jack unplugged when I cat'd that. Do you want me to
post it with the jack plugged in as well?

Make a diff of the state with HP (if any changes are found).

When you compile with --with-debug=detect option
(CONFIG_SND_DEBUG_DETECT=y kconfig), the driver will show the detected pin
configurations in kernel message.  Please show it, too.
