It was reported that the headphone output on ASUS UX430UA (SSID 1043:1740) with ALC295 codec is silent while the speaker works. After the investigation, it turned out that the DAC assignment has to be fixed on this machine; unlike others, it expects DAC 0x02 to be assigned to the speaker pin 0x07 while DAC 0x03 to headphone pin 0x21. This patch provides a fixup for the fixed DAC/pin mapping for this device.
