ALSA: hda/realtek - Avoid multi-ios conflicting with multi-speakers
When a machine has multiple speakers, we don't need to create the controls for multi-ios. Check the number of primary outputs beforehand. Note that this workaround might not work always with new codecs in future; this assumes that both speakers and multi-io jacks share the same mixers/DACs. If they are routed with different mixers, the individual mixer controls should be needed. But, so far, this doesn't happen with the existing ALC codecs. Signed-off-by: Takashi Iwai <tiwai@suse.de>
