I am currently completely out of road finding a solution for this problem.
I assume I am missing something blindingly obvious, and please point me in the right direction if this topic has been covered and I've missed it.
The problem is I can get picture on a Teradek Vidiu, but not audio.
Today I was live-streaming a conference using an URSA Mini Pro direct to a Teradek Vidiu Go through SDI. The Teradek went to Core and was pushed to the client's Grabyo.
The picture was fine, but there was no embedded audio, despite good levels on camera. No audio was showing up in Core, and the client reported no audio their end.
I pushed a second stream to a test my Facebook page and was getting picture, but not audio, which ruled out a problem on the client's end.
The audio was line level from a mixing desk, but I still had no audio when I switched to internals, or an onboard shotgun.
For plan B had a BM WebPresenter in my case, which I then plugged the SDI into, and the audio was fine. I managed to get the stream out through the Vidiu by routing the BMWP PGM Out into the encoder which worked. Core and Grabyo now had audio and picture.
What I don't understand is why there wasn't any audio? The fact it worked through the BMWP rules out mechanical damage to outputs and cables. And in a separate incident I had the same issue using a LiveU system months before, ruling out a Teradek bug.
Reading the manual it states the UMP outputs 48khz 24bit audio over SDI. Knowing very little about the nitty-gritty of audio, I can only suspect this is where the problem lies, but don't actually know the full implications of the above.
Any suggestions and/or solutions would be greatly appreciated!.
