Hi Marcus and anyone who can help.
I have double checked and all the windows audio devices I have used
for the audio source are 2 channels.
They work fine with WSJT-X, or MAP65.
The stereo channels I wish to use are the I and Q outputs from my
SDRPLay Duo using virtual cables
(I have tried the speaker outputs from the PC with GNURadio audio source
and get the same problem)
Does the audio source work with two channels on linux?
I am using the latest version of GNURadio 3.7.13.4 on a 64bit win 10 PC.
I am really stuck here. Nothing I try allows the second output to be
enabled.
Regards
Gary

Hi Gary, since we acutely changed things in the Windows audio sink:
What's your version of GNU Radio?
Generally, Windows seems to be of the conviction that the audio device
you're trying to record from only has one, not two channels.
Best regards,
Marcus

Try as I may I cannot get a second port working using the audio source
block.
When I set the number of outputs to 2 for stereo (as in the
documentation) I get the error below.
File "C:\Users\Gary\Documents\top_block.py", line 109, in <module>

return _runtime_swig.top_block_sptr_primitive_connect(self, *args)
ValueError: port number 1 exceeds max of 0
Am I missing something?
