Re: [Discuss-gnuradio] How to use gr-audio on Windows?

[Luong Tan Phong]

My problem here:

On Windows PC1, I've install gnuradio with gr-audio (using portaudio) from source code, write a program to read data from LineIn port on sound card. Every thing is OK.

On Windows PC2:
   1. I copy the gnuradio dlls from PC1 to PC2 (don't install gnuradio), included portaudio.dll, QT4Core.dll, ...
   2. Create a directory named .gnuradio in my %HOME%, here C:\Users\LTP\.gnuradio. In this directory create a file named config.conf. Set audio_module = portaudio.

   3. Copy my program from PC1 to PC2. The program can run but it can't read data from LineIn port on sound card.

Could you help me, please?

LTP.

I'm still a little confused.

You have a Windows machine that you can use with gr-audio.

You have a /second/ Windows machine that cannot use gr-audio.

Right?

As I said, the native Windows interface in gr-audio does not work. But
if you are using portaudio on one Windows machine, make sure your
other machine is set up the exact same way to use portaudio there,
too.
