Hi, I face a strange problem that my ctag's audio output and input didn't work suddenly and my oscilloscope just detected noise in the audio output. I have faced this problem before and this problem would be solved by itself after a while. It means that my ctag started working normally again after a while, even though I used the same code and settings. I have faced this problem twice and it is the third time.

the breakout at the back, where you connect your audio adapter cables and socket wires, seems to be mounted upside down
