Bugs item #3602435, was opened at 2013-01-28 11:49 Message generated for change (Comment added) made by uklauer You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=110706&aid=3602435&group_id=10706 Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: None Group: None >Status: Closed >Resolution: Invalid Priority: 5 Private: No Submitted By: jpcote (jpcote) Assigned to: Nobody/Anonymous (nobody) Summary: Unhandled buffer overrun Initial Comment: If I try to play a sound by specifying the type as 'coreaudio', I receive a ton of such warning messages : "./play WARN coreaudio: coreaudio: unhandled buffer overrun. Data discarded." While those messages are being output, if I press CTRL-C, the sound plays normally on my internal speakers. Here are examples of problematic commands : ./play -t coreaudio "MOTU UltraLite mk3" F_2.aiff ./play -t coreaudio default F_2.aiff: The problem remains if I set my MOTU UltraLite mk3 interface as the default via the Sound Control Panel. However, if I issue the following command, it plays fine over my internal speakers : ./play sound.aiff The same command seems to work on my MOTU interface (when set as default) but the sound is crackling. This is probably a different problem, though. I tried compiling directly on my machine (Retina MacBook) and the problem remains. I'm attaching the output of the installcheck should that be of any help. Here is the output with -V -V : F_2.aiff: File Size: 172k Bit Rate: 1.41M Encoding: Signed PCM Channels: 2 @ 16-bit Samplerate: 44100Hz Replaygain: off Duration: 00:00:00.98 In:100% 00:00:00.98 [00:00:00.00] Out:43.0k [ | ] Hd:5.0 Clip:0 Done.

A command like play -t coreaudio "MOTU UltraLite mk3" F_2.aiff is equivalent to sox -t coreaudio "MOTU UltraLite mk3" F_2.aiff -d and means: Read audio from the soundcard (followed by the file, when you press CTRL-C) and play it back on the default audio device. What you want to do is apparently either to set the AUDIODEV environment variable to "MOTU UltraLite mk3", then run play F_2.aiff , or to run sox F_2.aiff -t coreaudio "MOTU UltraLite mk3" (note "sox", not "play" here). ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=110706&aid=3602435&group_id=10706 |
