I was able to get gnuradio to successfully compile using the script available
at (http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGR) and I
updated my PYTHONPATH as the script instructed. However, none of the audio
examples are working. They run without returning any errors, but I don't
hear anything. As far as I can tell, I have ALSA installed (I'm using Ubuntu
10.04 with kernel 2.6.32-38, all updates installed). I tried updating
gr-audio.conf to use alsa and tried changing gr-audio-alsa.conf to use
plughw:0,0 instead of hw:0,0 - all to no avail. I don't believe oss is
installed on this system. Can anyone suggest a solutions? Thanks ahead of

Try passing the device string "-O pulse" to use pulseaudio, instead. You might have to install libpulse0, though. I've found this to be a more flexible and reliable sound system.
