Bandmates Can't Hear Me

[Terles]

I'm running the condenser mic on my double bass into an acoustic image ten2. I'm then connecting the direct line from my amp and a separate talk-mic through a behringer UMC202HD and the only thing my bandmates could hear was the talk mic. My settings were fine for me--I could hear everything well through the headphone out of the UNC, but there was nothing coming through at all from the line for my bass,

Thoughts?

In Jamkazam, under Audio Inputs when in a session, do you see the track for your bass?  When you play your bass, does the volume bar show movement in the green bars?  As an aside, make sure your Direct Monitor switch is turned off on your interface.
