Message d'avis :
In value[[3L]](cond) :
beep() could not play the sound due to the following error:
Error in load.wave(fname): incomplete file
Seems to be related to the audio package which does not think the file is fine.
I can get this to work
download.file( "http://www.wavsource.com/snds_2014-07-06_8028356563048763/sfx/ocean.wav",
"/tmp/ocean.wav" )
system( "open /tmp/ocean.wav" )
This uses iTunes which you can definitely assume is available. Otherwise we could use vlc, but it might not be on the PATH which is what nchar(Sys.which("vlc")) >= 1 cares about. Could do e.g. :
system( "open -a vlc /tmp/ocean.wav" )
Perhaps I should report the audio issue to @s-u
There is something strange with that wav file, vlc can play it but neither paplay or aplay can (which usually plays wav-files on Linux...):
> aplay /home/rasmus/Desktop/vykort/ocean.wav
aplay: test_wavefile:898: can't play WAVE-file format 0x0055 which is not PCM or FLOAT encoded
> paplay /home/rasmus/Desktop/vykort/ocean.wav
Failed to open audio file.
I could probe for and always use vlc, but then I get a couple of seconds of lag when playing the sound (at least the first time) which is not that nice. Will have to think about this for a bit...
The following does work though:
beep("http://www.wavsource.com/snds_2014-07-06_8028356563048763/animals/cat_meow_x.wav")
?
It kind of works, but the sound is different. Here is what I hear:

not quite a cat meow anymore.
AFAICT that is only using the WAV wrapper around a MP3 file - that is not supported by audio since it has no specialized decoders (like MP3, AAC, etc.) - it only handles pure (uncompressed) audio files.
