No sound when connected to sdi output

I've noticed that I can't hear any sound on my Ursa mini pro 4.6k when connected thru SDI on my external monitor, have anyone else had this problem?
The xlr and headphone jack input/output work fine.
I tested a different ursa mini pro and NO Problem.

There are some issues going on at the moment that some hardware does not support the audio embedded in the SDI output of the ursa camera, Some models apply.. Also a lot of users reporting that Audio does not go trough the Teradek Bolt. While wired it works. And other Sdi sources work perfectly.. So there is some issue with payload id's or flags, or bitrate that is not supported by all hardware.
