Hello, We using linux-2.6.27 on target board-AT91SAM9263EK. We are using ALSA library utilities (aplay &arecord). But by using these utilities we can’t do simultaneous playback andrecording. We performed following activity to come to this conclusion: //At the background we were recording #arecord –f cd record_test_file & //At the forefront we were playing pre-recorded audio file #aplay –f cd pre_recorded_file Our observation is that, recording stops when start playingfile. Kindly need your guidance for simultaneous playback andrecording of an audio file. Appreciates your help if you provide sample test programs (using ALSA API) for recording.
