Try to set Jack Function to Headset or enable b HS Mic. I can't find "b HS Mic" function. I can set "Input Select" to "ADC", and ten internal microphone is off, but I can't get any audio on input. I tried with "Jack function" both "headset" and "headphone". Do I need to enable microphone bias voltage somewhere?
