Re: [pygame] vista testing...



The scratching are with all music files I have tested. The music have a native sample rate of 44k so there should be no need to resample, and it does work when the output is changed to 22k. I have tested with 15 different pieces. Furthermore it worked ok in pygame 1.7.

If I start a bit into the music I get occasional scratching for the rest of the piece after that.

The change with sample rate makes me think it may actually have to do
with the particular sound samples as well? I understand that SDL is
somewhat limited on the sample rate conversions it supports - got
particular sounds files that sound scratchy you can send to test with?

also, when you say you get scratches after starting some way into the
music - do you mean you get like a pop when first playing the music,
or do you mean that you get scratches throughout the music after you
start it playing at a point in the sound?

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 ?
