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 From then on, every time I run the program it gives me: Playing Error: 128 Key has been revoked I tried to google around but no luck.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 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
