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 and recording.
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 playing file.
Kindly need your guidance for simultaneous playback and recording of an audio file.
Appreciates your help if you provide sample test programs (using ALSA API) for recording.
Thanks & Regards,
Prashant C.
