Between 2.6.27 and 2.6.28 my HP dv5 laptop lost sound output from the
integrated speakers. Headphones work correctly.

Bisecting identifies this commit as being the culprit:

    ALSA: hda: 92xx S/PDIF In support

    Add support for S/PDIF IN on reference boards quirks. Also disable the
    IEC958 capture switch on boards with GPIO0 enabled.

I am not sure if this is related to bug 12159, so I'm reporting it separately.
