[Discuss-gnuradio] Multiple Inputs/Outputs using Jack and Gnuradio/GRC?

[Rob Frohne]

Hi Everyone,

I need four inputs and four outputs from Jack for my tests, but it seems 
that only one works.  Here is the message I get:

audio: using audio_jack
Traceback (most recent call last):
 File "/home/frohro/.gnuradio/top_block.py", line 61, in <module>
   tb = top_block()
 File "/home/frohro/.gnuradio/top_block.py", line 51, in __init__
   self.connect((self.audio_source_0, 1), (self.audio_sink_0, 1))

   self._connect(points[i-1], points[i])

line 1443, in connect
   return _gnuradio_swig_py_runtime.gr_top_block_sptr_connect(*args)
ValueError: port number 1 exceeds max of 0

Does anyone have any advice?

Thanks,

Rob
