From: Takashi Iwai Date: Thu, 14 Jul 2011 13:31:21 +0000 (+0200) Subject: ALSA: hda - Re-add need_dac_fix check for multi-io jacks of Realtek codecs X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7b1655f5f21a9bd1eb8b478c5dab9b83de809edc;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git ALSA: hda - Re-add need_dac_fix check for multi-io jacks of Realtek codecs During the rewrite, the check of spec->need_dac_fix and the corresponding num_dacs change was dropped from the channel-mode control. This patch re-adds it, and also enables need_dac_fix for ALC880 as default, as this feature was originally introduced to fix h/w bugs of this chip.
