how to asynchronous playback with ALSA
 

i want to play sound asynchronously by linux programming
i test OSS, but it cann't support asyncronous playback
then, i test ALSA, it can support asynchronous playback, but when i wrote a sample programme, its callback function didn't work

please help me

whats asynchronous playback ?

and no need to create multiple threads ...

asynchronous means alsa playback sound, and concurrently with it programme do other work(graphics,...)whitout wait until finish playback
