1. Q3

   Is a headset plugged into each PC, and the one microphone into the host PC?

   How to tell: With no microphone, the host's Microphone picker reads "No microphone found. Plug one in to host." With no headset or speakers, the Headset picker reads "No headset or speakers found. Plug one in." The host PC needs a headset too: it plays the microphone in its own headset, and without one Host stops with the red banner "Could not open the output device: … (is a headset or speakers plugged in and turned on?)" The lists are read when the app opens and again after every Leave.

   What to do: Please plug the device in, then close and reopen the app, or press Leave once. If the host links but an amber line reads "The mic is sending pure silence. In Settings › Privacy & security › Microphone, let desktop apps use the microphone.", turn that setting on. The joining PC needs no microphone. If the voice feels late, please try a wired headset: a wireless one adds its own delay.

   On CO-OP Comms Client Only: Client Only needs no microphone, only a headset or speakers. With none, its Headset picker reads "No headset or speakers found. Plug one in."

   

   

   

   

Problems we know for step 4B

1. 4B-1

   The host PC's window shows nothing when the joining PC mutes.

   Why

   The joining PC's Mute only silences its own headset, so there is nothing to tell the host.

   Fix

   Nothing is wrong. Press Mute again on the joining PC so it reads OFF.
