As I see: when the twl4030_power_down is called from the twl4030_set_bias_level (SND_SOC_BIAS_STANDBY, SND_SOC_BIAS_OFF) it sets the codec to power-off state (CODEC_MODE:CODECPDZ = 0), which effectively turns off the digital filter, analog section, so basically everything. When the CODECPDZ is 0, APGA, DAC, analog output settings have no effect (they are powered off)
Right, that's what I thought. You'll need to fix this in order to use bypass paths since it will turn off the analogue.
