usb to fft1024

[amar1patel84]

Im having a problem getting the fft1024 to get a proper reading, although everything seems to be set up properly. fft1024_1.available() just does not seem to ever be available, even though my USB type is audio, and my computer is correctly outputting to the teensy. I have attached my code below

I had to change USB type to "audio + Serial" in order to see the values, but it was not working nonetheless

You need to fire up the audio chain which means including at least one class that can drive it, such as i2s_output.
From what I recall USB doesn't drive the chain, its expects something else to do it.
