I'm opening hw:0 directly, to avoid resampling. However, I'm receiving a report of a system returning EPIPE: https://sourceforge.net/tracker/index.php?func=detail&aid=1035604&group_id=37892&atid=421366 https://sourceforge.net/tracker/download.php?group_id=37892&atid=421366&file_id=103978&aid=1035604 This is apparently on an x86-64 system. Is this a known problem? Am I probably doing something wrong that just happens to usually work? I'm treating EPIPE as an unexpected condition, since it's not clear why it would happen here; should I have it call snd_pcm_prepare() and retry anyway? -- Glenn Maynard ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
