    How to use alsa for simultaneous recording and playback




      I am using alsa sound library for recording and playback on Intel Edison.

      I can do the recording and playback in a simplex way using alsa library.

      I am opening PCM in the blocking mode due to which playback cannot be done when recording is in progress.

      I want to perform simultaneous recording and playback.

      Does anyone know how to use alsa library for simultaneous recording and playback?
