I’ve connected my tape player to the USB port and when sound is playing and I record, it shows no sound coming through. It recognizes the USB connection and I have my mic slider all the way up. I even tried restarting Audacity with the connections still connected. Any ideas out there? See screenshot of what I have. I recorded with the tape playing full sound, straight line down the middle.
From the screen shot from Audio MIDI Setup we can see that “USBAudio2.0” device has one audio input. It is probably meant for a microphone. It is not appropriate for recording a stereo source.
In your screen shot of Sound Preferences the input level meter shows zero, which indicates that no audio is getting into the Mac.
You many want to look into getting a Behringer UCA-202 or similar audio-to-USB device.
