[alsa-devel] Code Example for Playing Sound in the Background

[GitHub issues - edited]

alsa-project/alsa-lib issue #17 was edited from 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
