>Description:
Hi Sanpei,

The STAC9766/67 codecs are not recognized with the pcm soundcard
in my lifebook C1110.  Therefore the soundcard doesn't work. After
applying attached patch the codec is recognized and the soundcard is
working.

>How-To-Repeat:
        N/A
>Fix:
Addition of codec id to ac97codecid array in sys/dev/sound/pcm/ac97.c
