ALSA: hda - Create "Digital Mic Capture Volume" correctly for IDT codecs
So far, the digital mic capture volume wasn't created. This is because IDT codecs have output amps for digital mics, not input amps, while input amps should be used for other analog pins. Thus the automatic capture volume creation should check both directions for digital mics. Signed-off-by: Takashi Iwai <tiwai@suse.de>
