    9. Codec: The possible bit rate values are L24, L16, DSD64, DSD64_32, DSD128, DSD128_32, and DSD256. Note that these values are sampling rate dependent. 10.Frame size (samples): This the frame size of the current source. 11.DSCP: The audio DSCP should be set to 34 for RTP AES67 or 46 for RTP Ravenna.

    7. Ignore RefClk GMID - accept source locked to any PTP master: This feature is useful when you want to connect a stream through Internet (for example with two PTP Masters (GPS) at each location. This allows making of connections with devices locked to different traceable PTP Masters. See RefClk PTP traceable on the Session Sources tab.
