Question

I would like to capture raw data from the audio out, using Python. In the Python docs it seems that using ossaudiodev works for this purpose. However, I am using Ubuntu 11.10, which has no /dev/dsp:

>>> import ossaudiodev
>>> ossaudiodev.open('r');
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IOError: [Errno 2] No such file or directory: '/dev/dsp'

Has anybody got a clue how to capture the sound my sound card outputs using Python?

Answer

I have got programs to work which require /dev/dsp by using

aoss <PROGRAM NAME AND ARGUMENTS HERE>

If you type aoss on Ubuntu's command line, it will tell you the package to install and that should, in turn, install the needed dependencies. If it doesn't work off the bat, you can try loading a kernel module such as sudo modprobe snd_mixer_oss.
