Hi I've acquired an Audio Cape Rev B http://elinux.org/CircuitCo:Audio_Cape_RevB for my Beaglebone Black.
Following the instructions I was able to make it work. The audio playback is working pretty well. However, I cannot test the audio input. I saw that it is a line level input (line in), so it cannot be connected to a regular microphone. I want to test it through an echo scheme. I will produce some sound through q source (connected to the line in input of the cape) and check the response in the audio output, through an earphone. I tried to connect the cape line in to the earphone output of an old cellphone through a male male jack cable (I saw in some forums that the line level is similar to the earphone output of some appliances, apart from the impedance difference.). Unfortunately, it didn't work. The interesting thing is that when the cable is connected to the cape audio input and the other connector is unplluged, I can hear the noise from static, similar to an unplugged to the amplifier electric guitar . Can someone suggest me a simple form to test the audio input?
