Re: [pygame] Sound still glitchy in 1.8.1rc1 on Ubuntu

Hi Gary,
  Making the mixer work great in all cases without tweaking numbers is indeed a goal for pygame. I would guess that in this case the problem may be something other than the buffer size, which is what was tweaked in 1.8.1 to be larger. This seems the case to me because you mentioned a higher sampling rate eliminates the problem for you.

To confirm, can you try a big fat buffer size with the original 22050 sampling rate? (basically something that should be able to fit the whole .44 second wave without mixing over time)
so something like this:
pygame.mixer.init(22050, -16, 2, 16384)
The lag will likely be longer, so I'm just curious if playback quality is good in that case.

Also, have you tried many other wav files? Any at different sampling rates? Is the problem consistent at 22050 for all samples tried, or are there some that don't seem to have problems?

2. Yes, fooling with the options to pygame.mixer.pre_init seems to always be the not very satisfactory answer. My understanding of the goal for 1.8.1 was to eliminate that requirement. Having users fool with numbers on a hit or miss basis is a sure way to drive them away.

That said, I found that forcing the rate to 44100 instead of letting it be at 22050 where it apparently went by default makes it sound better. Makes no sense that a higher sampling rate cures it but it appears to.
