Hi all,
We are developing a AES based speech encryption module using beagleboard. We have two beagleboard: one for encryption and other for decryption. We use audio-in/audio-out for sending speech. We have problem with synchronization of audio stream from encryption board to decryption board. Since AES is block cipher, the buffer content received by decryption board must be the same as sent from encryption board. Right now, we want to use some bytes as data header, but we don't now how to make this work. Any idea how to solve synchronization in ALSA?
Best Regards,
Arif
