If I follow this and use "all available sources", I get twice the
amount of data, the sources are interleaved in the input stream.

hdafg0: ADC02 2ch: Mic In [Jack]
hdafg0: ADC03 2ch: Mic In [Built-In]

With record.source=ADC02,ADC03 this records 4 samples ADC02.left, ADC02.right,
ADC03.left, ADC03.right per frame.

But audio(4) doesn't know about it, as the hardware sends data at twice
the rate, the result sounds like a half-speed recording with half
the volume (when one input is silent).
