First of all, I would like to apologize for the delay in response. It seems like I encounter some issues with notification reaching my mailbox. Sorry for the inconvenience.
As I understand it, you are inquiring about audio embed in 12G SDI. For your information, currently there is no specific IP supported for audio embed for 12G SDI which was supported in 10 series devices. For older devices, we have audio embed IP but it is no longer supported for 10 series devices. Sorry for the inconvenience. You would need to further look into coding the audio embed logic using core logic.
Sorry for the inconvenience.
