[Haskell-cafe] reading and playing music openAL

[Patai Gergely]

Hello,

The basic idea is that you have to define a source and repeatedly call
queueBuffers on it. I wrote an OpenAL version of the Hemkay module
player (example code without comments, with some horrible way to achieve
double buffering can be found at [1]), which can be compiled if you have
installed the hemkay-core package. Also, you might want to ask sound
related questions on the Haskell art list [2].
