@rjp9 ... yep I found the problem, it was that. I had the output put in Airplay instead of the built in output. Thanks a lot

Hello I have where my pure data dosen't create any sound even if the DSP is on. I tried
installing again, and restarting it. Every time I do it I make an easy test where I connect a number box with a 500 to an oscilator and then to a dac to see if it sounds, but nothing happens. Anyone knows what could be wrong ? It started doing this just this week and I don't know why.
