I am just starting to work with Alsa I compiled a test program from one of
the tutorials and I am getting this error message.
Unknown Error 126.
Does anyone know what error 126 is?
I am using "plughw:0,0" as the device name.
and this is the segment of code that generates the error.

for (i = 0; i < 10; ++i) {
if ((err = snd_pcm_writei (playback_handle, buf, 128)) != 128) {
    fprintf (stderr, "write to audio interface failed (%s)\n", snd_strerror
(err));
    exit (1);
    }
}


I am running Suse 9.3+kde 3.5

I hope this is the correct list to ask this.

If the err > 0, it tells you how many frames were written to the sound 
card. As you can see here, 126 frames were written, probably due to 
sound card's hardware buffer being full.
