If I understand the question, it's whether the microcontroller could output audio to the headphone jack. In theory it might be able to create low-quality, 8-bit audio, but I'm not sure if there would be enough processor power left after everything else that it does. If you could send an audio signal to the headphone jack you'd then need a custom headphone adapter, because I used a non-standard pinout on the jack that includes a 3V power source for the bell sensor, so you'd want to avoid connecting that to headphones. The adapter would also need a smoothing filter to convert the digital PWM signal to something close to an analog signal. So, in theory it might be possible, but it would take quite a bit or work for poor-quality audio, unfortunately. It's' a good question, though! One of my goals for the ultimate WARBL version in distant future is to have onboard audio.
