Routing ADC -> DAC in sgtl5000

Hello.

I want to pass signal from Mic to Line_out. From datasheet I knew, this coult be done through internal audio switch.

Full path is looks like: MIC_IN->MUX->ADC->SSS->DAC->LINE_OUT.

In driver I do something like this:
write(SGTL5000_CHIP_ANA_CTRL, SGTL5000_ADC_SEL_MIC << SGTL5000_ADC_SEL_SHIFT);
write(SGTL5000_CHIP_SSS_CTRL, SGTL5000_DAC_SEL_ADC << SGTL5000_DAC_SEL_SHIFT);

But no signal present at the output.

 

P.S. I know Line In -> HP out works good.

Thank You for any advice.
