ALSA: hda - Re-add need_dac_fix check for multi-io jacks of Realtek codecs (7b1655f5) · Commits · 戴 / test

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. Signed-off-by:
