The hardware can generate an interrupt at the beginning or the period (ptr = 0) and the middle of the period (halfway through the buffer). I didn't much time trying to understand all the internals of ALSA, so I submitted what worked. This latest version has alsaplayer working and the pcm test in alsa-lib. I've two channels playback but the third one cannot be heard (there seems to be no mixer control for it), so we probably need the specs to figure that one out. > the attached patch includes some fixes by me for the latest cvs, and > changes the periods to 2. I'll apply it to cvs now. Thanks, Francisco ________________________________________________________________ The best thing to hit the Internet in years - NetZero HiSpeed!
