The phase inverted channel has this bit: #define SNDRV_CHMAP_PHASE_INVERSE (0x01 << 16)

Hmm. On second thought, as mics are plugged in and unplugged during recording, the channel map will change. (E g, changing a digital mic with phase inverse, to a stereo line in)

Will we also need a notify callback in alsa-lib to know changes in the channel map?
