This may prove useful when writing openMHA configuration files.

system:playback_1 # IC1 Left Playback Data, mapped to LHP_6 (HP1 Left)
system:playback_2 # IC2 Left Playback Data, mapped to LHP_7 (HP2 Left)
system:playback_3 # IC3 Left Playback Data, mapped to LHP_8 (Not committed on PCB)
system:playback_4 # (Not connected)
system:playback_5 # IC1 Right Playback Data, mapped to RHP_6 (HP1 Right)
system:playback_6 # IC2 Right Playback Data, mapped to RHP_7 (HP2 Right)
system:playback_7 # IC3 Right Playback Data, mapped to RHP_8 (Not committed on PCB)
system:playback_8 # (Not connected)

system:capture_1 # IC1 Left Record Data, mapped to LINN6 (MIC1 Left)
system:capture_2 # IC2 Left Record Data, mapped to LINN7 (MIC2 Left)
system:capture_3 # IC3 Left Record Data, mapped to LINN8 (MIC3 Left)
system:capture_4 # (Not connected)
system:capture_5 # IC1 Right Record Data, mapped to RINN6 (MIC1 Right)
system:capture_6 # IC2 Right Record Data, mapped to RINN7 (MIC2 Right)
system:capture_7 # IC3 Right Record Data, mapped to RINN8 (MIC3 Right)
system:capture_8 # (Not connected)

They are the same order. Jack is also just using the alsa driver.
