Hi. Looking at it again, I've narrowed down to the following few : ossaudiodev http://docs.python.org/library/ossaudiodev.html Linux only but included in python pygame http://www.pygame.org/docs/ref/mixer.html#pygame.mixer.Sound Most occurring answer on forums and mailing-lists on the net for this question. Might be a little overkill... PortAudio http://people.csail.mit.edu/hubert/pyaudio/ http://www.portaudio.com/ Cross-platform, packaged for debian. Could fit my needs as well. Generally, the examples I find are about opening and playing a wavefile. I guess I'm gonna have to work a little to feed them a homegrown sinewave of arbitrary frequency. Regarding PortAudio, python /usr/share/doc/python-pyaudio/examples/system_info.py (and other examples) yield complaints about jack not being running. I assume they could be tweaked to use ALSA instead. I haven't had time to dig any further. If I come up with something, I'll keep you posted. Thanks for your answer. -- Jérôme -- http://mail.python.org/mailman/listinfo/python-list
