Subject: ALSA: hda - Fix SPDIF out regression on ALC889
From: Takashi Iwai <[email protected]>
commit 20b67dddcc5f29d3d0c900225d85e0ac655bc69d upstream.
The commit 5a8cfb4e8ae317d283f84122ed20faa069c5e0c4
ALSA: hda - Use ALC_INIT_DEFAULT for really default initialization
changed to use the default initialization method for ALC889, but
this caused a regression on SPDIF output on some machines.
This seems due to the COEF setup included in the default init procedure.
For making SPDIF working again, the COEF-setup has to be avoided for
the id 0889.
