Code Example for Playing Sound in the Background

[leimao]

Hello, I wrote a simple C++ player based on alsa-lib which allows me to play wav files. I wonder if there is any convenient way to modify my code so that I can play the the wav file in the background and the main program is executing something else, say, a while loop. Edited and Updated: I tried to use std::thread and std::async, I was able to play the sound in the background. I looked at the header file of alsa-lib, it seems that alsa-lib natively supports playing sound asynchronously. I wonder how I could do it easily. Thank you very much. Best, Lei
