Re: [pygame] vista testing...

[Bo Jangeborg <bo@xxxxxxxxxxx>]

The buffer setting doesn't seem to make a differens.
The key seem to be the sampling rate. Lots of scratching at 44k sound
but OK at 22k. But even then I get scratches if I start some way into 
the music
rather then at the start. The later problem I had in pygame 1.7 too.

In pygame 1.7 music worked OK in Vista at 44k.
I have tried both ogg and mp3 in pygame 1.8.
Have you tried playing music at 44k on XP machines?  Maybe this is a more
general problem.

Another thing that seem to have changed is that if a path to a sound file
is wrong it doesn't cause an exception. Instead it returns an empty 
sound object..
Is that really intended ?
