Considering the corresponding ALC target bits are 7:4, the control is initialized with 0xB, which is one step above the maximum value 0xA allowed by the driver. This means that either the hardware default is wrongly set to 0xB instead of 0xA, or the specs are incorrect and instead of having the range 0xA-0xF mapped to -1.5 dB, the single value 0xA should have been mapped to -1.5 dB and the remaining range 0xB-0xF to 0 dB. Increment the max value allowed for ALC Capture Target Volume control, so that it matches the hardware default.
