Hello,
I have connected ipod to my hardware (using USB) and i want to read the audio pcm data from ipod. I am running following section of code to detect connection of ipod. But i am not finding any capture device connected. Am i giving some wrong name of capture device ? If wrong how can i find correct name of Audio Capture device.
/***********************************************************************************************************************************************/ const char *capture_device="plughw:1,0";
while((retVal = snd_pcm_open( &pcm_capture, (const char *)capture_device, SND_PCM_STREAM_CAPTURE, 1))!=0) { if (retVal != 0){ printf("Opening Capture device FAILED\n"); printf("Still waiting for Capture device to be connected\n"); usleep(5000); } } /***********************************************************************************************************************************************/ OUTPUT :
Opening Capture device FAILED Still waiting for Capture device to be connected ALSA lib pcm_hw.c:1433:(_snd_pcm_hw_open) Invalid value for card Opening Capture device FAILED Still waiting for Capture device to be connected ALSA lib pcm_hw.c:1433:(_snd_pcm_hw_open) Invalid value for card Opening Capture device FAILED Still waiting for Capture device to be connected ALSA lib pcm_hw.c:1433:(_snd_pcm_hw_open) Invalid value for card Opening Capture device FAILED Still waiting for Capture device to be connected ALSA lib pcm_hw.c:1433:(_snd_pcm_hw_open) Invalid value for card Opening Capture device FAILED Still waiting for Capture device to be connected . . . . . . . /*Continues*/ . . . . . . . . . . . . .
