FFmpeg/libavdevice can grab from ALSA, OSS or jack. As an example of the latter: ffmpeg -f jack -i JACK_READABLE_CLIENT_ID jackout.wav The same can be done programmatically using the libavdevice API. > What I do is to open /dev/dsp with oss format (av_find_input_format).

I think you need to explicitely specify the demuxer, alsa in this case, I'm not sure FFmpeg is smart enough to figure it out by itself from the name of the device.
