When I use the following call with device_to_use == "plughw:0,0"
it works just fine. When I try to use device_to_use == "hw:0,0"
it gives a segmentation fault. Is there a special initialization needed
to use the hw plug?
err = snd_pcm_open (&alsa_dev, device_to_use, SND_PCM_STREAM_PLAYBACK, 0);
Thank you for any clarification.
