ALSA: hda - Fix wrong volumes in AD1988 auto-probe mode
Don't create mixer volume elements for Headphone and Speaker if they use the same DAC as normal line-outs on AD1988. Otherwise the amp value gets screwed up, e.g. https://bugzilla.novell.com/show_bug.cgi?id=398255 Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
