As I understand it, you are inquiring about using SDI audio embed IP in C10GX devices. For your information, audio IP is not supported in 10 series devices. Therefore, you would not be able to use the audio IP in C10GX devices. Sorry for the inconvenience.
Yes, your understanding is correct. Recently Factory releases SDI Audio IP for A10 devices. However, as per my understanding, I am not aware of any plan to support for C10 devices currently. Sorry for the inconvenience.
