From: Takashi Iwai Date: Mon, 25 May 2009 06:06:02 +0000 (+0200) Subject: ALSA: hda - Add missing check of pin vref 50 and others in Realtek codecs X-Git-Tag: v2.6.30-rc8~52^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=461c6c3a0a23a8fac1a4b636e93ff5dfe599a241;p=platform%2Fkernel%2Flinux-stable.git ALSA: hda - Add missing check of pin vref 50 and others in Realtek codecs Some Realtek codecs like ALC861 seem to support only VREF50 while the current driver assumes it's only VREF80. Check other VREF bits to set the correct value.
