SubjectRe: PROBLEM: SIS7019 stops recording after 42 min

Strange? The program I am actually using is one I have written myself.
I was sure I was using the old method as I open(2). In my program I
int fd = open("/dev/dsp", O_RDWR);

This should not go through ALSA (I think). I gues one should use
something with "snd_pcm_open()" to use ALSA.

I really don't understand why I do not see this problem on other
hardware using the same compiled code.

If the problem is ALSA, how can I then turn it off?

Thanks for your investigation.
