You can set the default audio driver by creating a ~/.gnuradio/config.conf with this content: [audio] verbose = True #audio_module = audio_oss audio_module = audio_alsa Try specifying -I plughw:0,0 or -O plughw:0,0 on the command line if you're using ALSA. plughw implements a resampler. FWIW, we find that ALSA generally works better than OSS.
