This is a good question. 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) -- Péter _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
