Hi,
I am a beginner.
I tried to use Teensy 4.1 and Digilent I2S DAC board to achieve USB audio streaming but failed. I just use the example in arduino which named "PassthroughUSB". The USB audio interface is ok but there isn't any sounds come out. The DAC board use cs4344 DAC chip. I guess the problem is in the I2S protocol but I don't know what should I do because I don't know where can I modify the code about I2S communication in this example, there are only several "audioconnection" command in this example. By the way, I have a question that whether the USB audio mode in this example is asynchronous or synchronize? How can I achieve asynchronous mode in Teensy 4.1?
I would appreciate if someone can give me some suggestion.
