 Hi All,

Hi Spring!
 
      I'm a new member to learn how to write a ALSA application.


 
Is there a reason that you want to learn ALSA specifically? Or do you want to start audio programming in general? I might advise writing a JACK client if its audio coding you want to get into :)
  


I analyze the source code of aplay and very confused on follow interfaces:
            snd_pcm_playback_info()
             snd_pcm_playback_format()
            snd_pcm_playback_params()


 
Can't help there I'm afraid: I'm a JACK coder.. :) -Harry
