Cannot hear voice of someone I'm jamming with

Sounds like the other guitar player didn’t set up his chat mic, or not correctly. When you go through the gear setup, there is an option offered to use the built in mic for chat. It is not the default if you have an audio interface installed. It assumes you have a mic input in your audio interface (i.e., at least two inputs in the interface). If you don’t, you have to select the built in for chat. He will have to delete his audio interface from JK and reinstall it again under Audio Setup > Add Gear. Hope this helps.
