OS X 10.4.11
Audacity 1.3.13
Input: iMic USB audio system (recognized in Audio Midi Setup screen) identified as 2 channel 16 bit
Sound coming from cassette deck can be heard on headphones
Audacity preferences/Devices/Recording: No devices found; 2-channel
Audacity preferences/Devices/Interface: Core Audio
Audacity preferences/Quality/Sampling: Sampling Rate = 44100; Sample Format = 16-bit

I'm hoping there's a simple solution!

Try this.
Apple (upper left) > System Preferences > Hardware > Sound > Input. Is the USB device listed there and does the blue sound meter jump in time to the music?

Make sure Audacity Preferences > Devices is selected correctly and restart Audacity. Audacity should list a USB sound device.

That help? If you change enough settings, Audacity can get behind and require a restart.
