I can't seem to find out how you check the sound format that mixer is using. For example, when I request 8 bit signed format, I get 8 bit unsigned, and all my samples sound terrible (they are raw samples so I have to load them into a sndarray.) But to find this out, I had to write a test in C using SDL_OpenAudio because even SDL_mixer cannot seem to tell you this. Checking the struct output by SDL_OpenAudio seems to be the only way to know, so if you don't call it yourself, you can't know, and Mix_OpenAudio hides the output from SDL_OpenAudio...
Also it would be nice to have a pygame.mixer.Sound.from_buffer() function similar to the Surface.from_buffer() in that it does not require Numeric. I don't have anything against sndarray and surfarray but if you only need to convert your samples/images once it seems unnecessary to add a further dependency on Numeric. In my case I'm loading 1 bit bitmaps and converting them to 8 bit, and imageop.mono2grey is fine for this. Unfortunately it would be much less useful for sound without the ability to check mixer format, so if anyone can solve that problem, I'll try to code from_buffer for sounds. -- Alistair Buxton [EMAIL PROTECTED]
