Hello, I have a USB sound card (an short wave receiver) connected to my micro. I can save the samples into a .wav file. It's works, playback with any software is ok. Now, I would like send the samples to the boards sound card too. But the result is a terrible noise. (Sound parameters are set on output device, the same as input device) Has anybody an idea or a link for a howto copy samples from /dev/dsp1 to /dev/dsp? thanks skip
