[ALSA] hda-codec - Fix SPDIF output
Fix SPDIF output (at least on Realtek codecs). The DIGI_CONVERT verbs have to be reset before the PCM stream is set up. Otherwise the digital setup is screwed up. Also, check the AMP capability before setting AMP of the digital out widget. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
