Hi,
I do not know much about audio. The "newmessage.wav" file from
http://git.gnome.org/cgit/ekiga/tree/sounds is strange because it is
correctly played by aplay, vlc plays it but not the same thing is heard,
and xmms does not play it all. Standard windows programs do not play it
either. Could someone tell me what's special with this file?
Thanks,

samplerate maybe?
Did you check with sndfile-info?

Hi,
It shows a sample rate of 44100. However, ring.wav and voicemail.wav
are also at 44100, and they play well.

I do not even get a soundfile, but a hexdump as I try to download it
http://git.gnome.org/cgit/ekiga/tree/sounds/newmessage.wav

Hi -
If you look at the two outputs below you'll see that newmessage.wav
has some extra info embedded in it - possibly newmessage.wav is
actually a BWF-format file?

No, that's just standard RIFF metadata. The file ring.wav uses exactly
the same sample format, so any program that plays that file but not
newmessage.wav is just an example of Sturgeon's Law.

Hi,
Indeed, I see the following extra information:
LIST : 74
INFO
ISFT : Sonic Foundry Sound Forge 6.0
IENG :

but this is just comment, so nothing interesting...
Can someone save it in .wav playable by classical audio programs (e.g.
vlc, xmms)?

But apart from the advanced metadata, there's a much more fundamental
difference: the first file listed above is stereo, the second is mono...

When opening it with audacity, I see that this file has two "sounds",
one which starts at sec.0, and another one starting later. It seems to
me that only the second "sound" is heard in vlc.
Isn't it reproducible to you? Do you hear the same thing with aplay and
vlc?!

Eugen
vlc plays it
but not the same thing is heard,
What is the difference that you are hearing?
