[ALSA] hda-codec - Disable shared stream on AD1986A
AD1986A has a hardware problem that it cannot share a stream with multiple pins properly. The problem occurs e.g. when a volume is changed during playback. So far, hda-intel driver unconditionally assigns the stream to multiple output pins in copy-front mode, and this should be avoided for AD1986A codec. The original fix patch was by zhejiang <zhe.jiang@intel.com>. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
