What would be more idiomatic here would be to make VAG a supply widget and then connect it to DAC and ADC rather than have the event on both - It looks like with your current code simultaneous playback and capture will break, you'll run through the power sequences twice and if you stop one stream it'll power down the other.
- {"Mic Bias", NULL, "MIC_IN"}, /* mic_in --> mic bias */
- {"Capture Mux", "MIC_IN", "Mic Bias"}, /* mic bias --> adc_mux */
This should be in the machine driver.
