[ALSA] hda-codec - Add support of 96kHz back
Added the support of 96kHz sample rate back. Although the rate isn't listed in the ACC_PAR_PCM bits but si3054 codecs do support this rate explicitly. Now fixed the deteciton code not to check this extra bit. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
