Description of problem:

After suspend/resume using pm-suspend or "echo -n mem > /sys/power/state", sound
always uses laptop's internal speakers whether or not something is plugged into
line-out.

The laptop is a Dell Latitude D820. The chipset is "82801G (ICH7 Family)", and
the kernel module is snd_hda_intel.

This is a recent regression as it works OK with the previous kernel
(2.6.18-1.2798.fc6).

Version-Release number of selected component (if applicable):

Kernel: 2.6.18-1.2849.fc6

How reproducible:

Always

Steps to Reproduce:
1. Suspend using pm-suspend or "echo -n mem > /sys/power/state".
2. Resume
3. Play an MP3 or something
  
Actual results:

Sound plays through internal speakers even though headphones are plugged into
line-out.

Expected results:

Sound plays through headphones as it did before suspend.

Additional info:

Boot into the previous kernel, 2.6.18-1.2798.fc6, and all works as expected.
