Default values of register 28h and 2Ah depend on whether the device is a primary or secondary, and whether SPDIF
capability is enabled by pulling pin 44 SPEN high. The conditions shown are for a primary codec with SPDIF capability.
Register 5Ah is write only. When writing to this register all bits except MPM (bit 4) must be written as 0, otherwise device
function can not be guaranteed.
