Hi, We are working on audio processing (encryption-decryption) and audio will be sent using radio. Our configuration is : Audio source - ALSA audio in - encryption - ALSA audio out - transmission over radio (now we still use audio cable) - ALSA audio in - decryption - ALSA audio out - speaker. So data will be sent through radio channel and its converted to analog form by ALSA PCM during playback. We want to solve synchronization issue by using data header so that we can decrypt correct data block. So far we still unable to verify that data we received in the decryption side is similar to data that we sent from encryption box. Supposed that we filled buffer in encryption box with some values, when we check buffer in decryption box, we can't get same data. Our guess that data somehow changed in digital-analog/analog-digital conversion or we might make mistakes in filling the buffer so data is not compatible with ALSA PCM. Any suggestion to solve this problem? Thank you, Best Regards, Arif _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
