Folks---
I just successfuly compiled GnuRadio and its dependencies. (YAY!!) I have,
however, run into a slight snag with audio.source(). When running anything
using this little gem, I get the following (example output from
spectrum_inversion.py):
audio_alsa_source[hw:0,0]: set_channels failed: Invalid argument
Traceback (most recent call last):
File "spectrum_inversion.py", line 37, in ?
main ()
File "spectrum_inversion.py", line 32, in main
fg.start ()
File
"/home/henry/gnuradio/lib/python2.4/site-packages/gnuradio/gr/flow_graph.py",
line 69, in start
self._setup_connections ()
File
"/home/henry/gnuradio/lib/python2.4/site-packages/gnuradio/gr/flow_graph.py",
line 98, in _setup_connections
self.validate ()
File
"/home/henry/gnuradio/lib/python2.4/site-packages/gnuradio/gr/basic_flow_graph.py",
line 164, in validate
raise ValueError, ("%s::check_topology (%d, %d) failed" % (m, ninputs,
noutputs))
ValueError: <gr_block audio_alsa_source (0)>::check_topology (0, 1) failed
Any ideas as to what may be causing this?
TIA,
