    Hey there, no need to apologize :) Yes, PCM1681-Q1 is my workhorse and it worked straight away with T4 in both I2S and TDM mode. I'm using it in hardware config because it requires no pins or code...

    Hi, alfa66. Nope, I tried a zillion workarounds and nothing worked as it should :(

    Yeah, I figured out loop() cycle is a very low priority process and it gets intetrupted very often by a bunch of other things. Lesson learned - don't use loop() with GetBuffer/PlayBuffer, or in fact...

    Teensy Button is IMHO one of the best features I've ever seen on a MCU board. If your code is voluminous the compiling can take a long time, and this can be a problem if you're testing something new:...

    I'm actually using three interrupt routines in my code, not counting the Audio Lib (which I don't have any control over) :D One fast at audio rate (44.100Hz) to produce the complex waveforms, one...

    Like I said, it was tested on T3.6 for hours and it works very well. I'm aware it's potentially unsafe, but:

    Cheers people, hope everyone is okay!

    I've been working on an audio project with T3.6, recently migrated my code to T4.0 and I'm facing several issues/problems that I don't really know how to...
