the above error message is the key.  Debugging linux audio can sometimes be a pain, here is one place to start:
   http://gnuradio.org/doc/sphinx/audio/index.html

That page describes the audio sink block, the second parameter of which is the name of the audio device, which is set using the -O option of scope.py.  If your system uses pulseaudio you can try '-O pulse' etc.

Another thing to try is to see if alsa is even installed:
   dpkg-query -l | grep -i alsa
