Subject[ALSA] [regression] No sound on ALC861 Analog with current git

Hi Takashi,

I've found that my sound card is muted with current git: it's recognized,
controls are set correctly, etc., but there's no sound in speakers. I've
bisected it down and found that this issue was caused by:

commit f6c7e5461e9046445d50c5c7a9a4587824239623
[ALSA] hda-codec - Fix auto-configuration of Realtek codecs

This patch fixes some bugs in the auto-configurator of Realtek codecs:
- add missing pin set-up for speaker pins
- fix the speaker auto-mute function not to conflict with the existing
"Speaker" mixer switch

Signed-off-by: Takashi Iwai <tiwai@suse.de>


Exact problem lays in alc861_auto_set_output_and_unmute() migrated to
alc_set_pin_output(), which now calls:
snd_hda_codec_write(codec, nid, 0, AC_VERB_SET_AMP_GAIN_MUTE,
AMP_OUT_UNMUTE);
Previously alc861_auto_set_output_and_unmute() was using dac_idx instead of nid.
I've added some silly printks and it looks like on my system there's a mismatch
which is causing this problem:
Called alc861_init_multi_out. Line outs: 1
Called alc861_auto_set_output_and_unmute with dac_idx: 3, nid: 11
Called alc_set_pin_output with pin_type: 64

Reverting change in alc861_auto_set_output_and_unmute() fixes problem (rfc patch
below).
