tas2562_volume_control_get() assumes that Digital Volume is only changed using the correspondent ALSA Control. However, it can also be changed by directly writing to DVC_CFG[1-4] registers, or by a software reset.
To ensure tas2562_volume_control_get() returns the current digital volume level of the amplifier, update the function so that it reads the registers instead of returning the data internally stored.
