Audio device in doesn't work

I’m trying to use audio device in but it doesn’t detect the audio that i’m playing. I change the reproductor and also activate all the parameters but nothing happens :frowning:

I also have that device on my machine but have never used it. Can you confirm you have signal coming into it by going to the Windows ‘Sound Control Panel’ and looking the ‘meters’ beside that device. You should see green level showing up as you see here on my microphone.
