[ALSA] hda-codec - Use model=ref for some Dell laptops
Takashi Iwai [Fri, 25 Aug 2006 11:11:26 +0000 (13:11 +0200)]
Force to choose model=ref for some Dell laptops with STAC9200 codec
chip for fixing the silent mic recording problem (possibly due to
a BIOS bug).  Reference: ALSA bug#2038
So far, applied to Inspiron 630m, Latitude D620 and 120L.
