[alsa-devel] snd_pcm_writei error 128 Key has been revoked

Hello

I'm a newbie to ALSA, in fact to sound programming at all. I tried a simple program for a beginner. When I got to this line:

err = snd_pcm_writei (playback_handle, buf, bufsize); printf("Playing Error: %d %s\n", err, snd_strerror(err));

the first time it played the sound that I wanted then I Ctrl-C the app. From then on, every time I run the program it gives me: Playing Error: 128 Key has been revoked

I tried to google around but no luck. Hope someone can help.

Thanks Paulos Siahu
