Hi,
I'm trying to figure out where to insert code to perform a loopback test.
In my app I have I2S_CHANS_ADC=6 and I2S_CHANS_DAC=4 and I want to take samples from the last stereo pair of my ADC:s (4,5) and copy these to last stereo pair of my DAC:s (2,3). Thus override any samples coming from the USB host for those particular channels.
So far I tried to modify the "DoSampleTransfer" funtion in audio.xc without any luck...is this the right place to do this?

Hi. Not an audio developer but perhaps you can study the following examples:

Thanks for your reply. Yes I'm aware of these examples. However I'm looking for a way to modify the audio usb sw framework.
