Hi, I've this application that return a wav file, it is something like this: # ./my_application <audio_number> <audio_file_wav> Then I can get the audio that this application creates and play with: # aplay -D plughw:1,0 test.wav And it works. But, what I want is to send this audio directly to device node, or something like this: # ./my_application <audio_number> /dev/snd/pcmC1D0p But I get the following error: cat: write error: File descriptor in bad state It is the same as if I try to cat a file to the device with: # cat test.wav > /dev/snd/pcmC1D0p I'm currently using a USB headset. None of the audio devices are created (i.e: /dev/audio /dev/dsp) I was informed that I can't get sound from writing data directly to the device node with ALSA, but I would like to ask you guys if some of you knows how to get over this problem. Thank you for your time. Regards, Douglas ------------------------------------------------------------------------------ Come build with us!
