[alsa-devel] ALSA synchronization
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
Hi,
I write a sound card driver which supports multiple streams and each stream should go to a specific device. I have written the driver to accept multiple playback streams and an application to create multiple playback streams as well.
Now, I am not able to find a way to send the device type to the driver from my application. I want to attach the device type to the stream. Could anybody help me?
I am thinking of using sysfs entries for send and receive the stream specific information? Is it acceptable to ALSA community?
Thanks
Sing
