[Elecraft] OT - K3 Help needed Cocomodem+MacBookAir+PSK31

[Randy Cook]

If you are using this config, I could use some help with setup, offline email please. 
Current config is K3/100 to iMic to MacBookAir 13 to CocoModem. 

I/O from K3 to iMic (set on ‘mic’ position) external sound card, to USB port on MBA. I/O audio on Mac set to external USB device.
Can get waterfall image on Cocomodem, but very faint signals, none readable. Can hear signals on K3. Seems to be a input level problem. 
Followed K3 Manual for PSK31 setup. Line out level does not seem to matter.
Cocomodem settings worked a couple of years ago with Desktop iMac and my K3.
Running out of ideas, but it is probably something simple I overlooked

Thanks in advance for any advice.
