Re: [Discuss-gnuradio] Audio Source Sound Card L and R Channels

[Marcus Müller]

Hi Rob,

Might be part of the things that don't work well in our windows port.

Can you try the image from https://wiki.gnuradio.org/index.php/GNU_Radio_Live_SDR_Environment ? The direct downloads are a bit special due to SSL issues right now, but the torrent should be really fast (my server is webseeding it).

Best regards,

Marcus

Hi everyone, As part of my training duties, I hope to use GNU Radio to demonstrate the concept of using I and Q for modulation and demodulation. I am using V3.7 Windows 7 binaries for my platform. Everything is going well except when I set the 'Audio source' to 2 output channels I get a: " ValueError: port number 1 exceeds max of 0" error. (see file attached) Example1.grc Both channels in the sound card are working for other applications such as a Software PC scope. Can somebody offer any suggestions please? Regards Rob.
