[AudioI] C++ Language Code examples

[antoine souchaud]

Hello, 

I am currently interning at an audio company and I need to work with the audioinjector octo sound card. I need to receive 4 independant mono signals, process them and send them out as an stereo output. To code this, I am using the PortAudio library, however I am getting error messages such as: 

ALSA lib pcm.c: 2642 :(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear
  ALSA lib pcm.c: 2642 :(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe
  ALSA lib pcm.c: 2642 :(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side 
ALSA lib pcm_usb_stream.c: 486 :(_snd_pcm_usb_stream_open) Invalid type for card
  ALSA lib pcm_usb_stream.c: 486 :(_snd_pcm_usb_stream_open) Invalid type for card 


I was wondering if someone could send me C example codes to program the octo sound card. Anything to let me get a better start. 
Thank you very much for the help.
