If it helps, I pasted the source code here so that you can view it nicely: http://pastebin.com/fCicqctq
which sound card are you using ?
The program did not run on my two sound card since you are using 160 frames and mono
are you using "pulse" device for testing since only pulse device return the error messages "could not read from capture device: Resource temporarily unavailable" ?
Yes, I am using pulseaudio since my hardware sound card (an audigy 2) does not support the period size I'm using.
The error message above is is from my own program (line 444):
----------------------------------------------------------------- if ((ret=snd_pcm_readi(capture_device, buffer, 160))<0) { if (ret == -EPIPE) { fprintf(stderr, "XRUN while reading from capture device: %s\n", snd_strerror(ret)); snd_pcm_prepare(capture_device); snd_pcm_start(capture_device); } else { fprintf(stderr, "could not read from capture device: %s\n", snd_strerror(ret)); exit(EXIT_FAILURE); } } -----------------------------------------------------------------
cheers, stefan
