[AudioI] Mic / Line both active?

[Ron]

Hi,

Is it possible to configure ALSA to have both the Mic and Line IN active 
on the Zero? The Zero will be embedded into a device we are designing 
that will have the MIC and phones connections connected to 3.5mm jacks 
on the front of the device.  We would like to have the Zero INPUT/OUTPUT 
connected to 3.5mm jacks on the rear of the device.  When I set the Zero 
with supplied script asound.state.MIC.thru.test I see the MIC configured 
when I run alsamixer.   When the Zero is configured with 
asound.state.RCA.thru.test, I see LINE IN when running alsamixer. I 
would like to have both configured in ALSA.  Is that possible and if so, 
please provide the specific details on how to accomplish that.  I know 
very little about how to develop ALSA configurations.
