Android : ALSA speed control in playback

on Tuesday, September 23, 2014


I need an urgent help in using ALSA.


I am trying to play the pcm data using alsa in my android board using libalsa-intf but I observe two issues:



  1. The play speed is more than I expected.

  2. Some buffer under runs occur during long play.


Is there any way to control the speed of the play ?


Is there any way to avoid the underrun which occurs rarely ?
