Hi
I’m trying play some 16bit mono samples from memory. For that I’m
using Mix_OpenAudio function to initialize the audio device with only
a channel and 44100hz, and later I create the Mix_Chunk with
Mix_QuickLoad_RAW function. The samples sounds well when I use the oss
alsa emulation driver, but the problem comes when I use the alsa
driver, the sound has lots of annoying clicks. When I initialize the
audio device in stereo it sounds well.
How can I fix this without using oss?
Thanks and excuse my poor english,
Rodland.
This happens to me too. Mine are 16bit and 22050hz. I do it exactly
the same and use ALSA.
I think it might be related to the whether they are signed samples.
Any ideas?

If everything plays incorrectly, it’s possibly an ALSA bug; if
everything else in SDL_mixer is playing correctly except that sound,
it’s definitely an SDL_mixer bug (since in that case, SDL_mixer would
handle the conversion to a format it’s otherwise playing correctly already).

Mix_QuickLoad_RAW says that it is not converted, but both of us are
confused about the format probably.
