On a HP Envy TouchSmart laptop, there are 2 speakers (main speaker and subwoofer speaker), 1 headphone and 2 DACs, without this fixup, the headphone will be assigned to a DAC and the 2 speakers will be assigned to another DAC, this assignment makes the surround-2.1 channels invalid.
To fix it, here using a DAC/pin preference map to bind the main speaker to 1 DAC and the subwoofer speaker will be assigned to another DAC.
