Hi All,
Say hello to everyone!

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
