Subject: ALSA: Enable SPDIF output on ALC655
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c872e8cab5b7cab0696bcf09c6f03c972edc1c49;p=deliverable%2Flinux.git

ALSA: Enable SPDIF output on ALC655

Some hardwares with ALC655 codec don't indicate the proper ext id bit
for SPDIF output although it supports.  Force to enable the bit.
