not able to use MIC 2 of UR242 with skype

hi, I hope this is the right discussion

due to coronavirus isolation I use skype to communicate with friands of music
I attach guitar in MIC 1 and a dinamic microphone in MIC2

if I use locally everything is OK and I hear both input from the headsets
when I go on skype only MIC 1 is working and there is no way to talk with the microphone of MIC 2

what to do? I need to play with some friends


hi, no one is there?
is it a difficult topic? or is the wrong forum?
