1) Are you using the built in mic or an external one? 2) By "not detected" do you mean "doesn't appear in the list of audio input devices" or "doesn't seem to hear me playing"? There is an input monitor (input volume meter) on the player and in the audio settings view. If there is a signal getting thru then that meter should be moving. If FATpick is hearing your mic but not detecting any notes then the troubleshooting guide at https://www.fatpick.com/support/troubleshooting https://www.fatpick.com/support/troubleshooting has some tips that might help. If the mic is seen as an input device but the audio signal isn't getting thru then you could check that both the system (sound control panel) and FATpick (settings > audio) have the input volume turned up high enough. If there mic is not seen as an input device at all I don't have any troubleshooting advice off the top of my head (short of using a different input device). If you can't solve the problem feel free to contact me as rod@<the-domain-name> or using the contract form on the website. I'd be happy to help you troubleshoot the issue.
