Red Hat Bugzilla – Bug 786128
Headphone jack in docking station is not operable, from kernel 3.2.1 forward

Description of problem:
Beginning with the 3.2.1 kernel, the headphone jack on my docking station (Dell Port Replicator) is not operable. This problem persists in the 3.2.2 kernel. The headphone jack on the actual laptop (Dell E6400) does work. Reverting to the 3.1.9 kernel restores functionality of the docking station headphone jack.
Version-Release number of selected component (if applicable):
Persists at each reboot
Steps to Reproduce:
1. Start with kernel 3.1.9 or earlier; headphone jack works fine.
2. Upgrade to kernel 3.2.1 or newer
3. Try playing music / sound / any audio media
No sound from headphones when plugged into the docking station. Sound settings in GNOME indicate that an audio program is working.
Sound should come from the headphones
Fixed in kernel 3.2.3-2.
