ALSA: hda - Use the primary DAC for all aamix outputs
When setting up the aamix output paths, use the primary DAC instead of the individual DAC for each output as default. Otherwise multiple DACs will be turned on for a single aamix widget, which results in doubly or more volumes, because the duplicated signals will be sent through all these DACs for a single stream.
