davinci resolve can't output sdi audio ?

PostThu Oct 23, 2014 5:11 am

My system MacPRO 5.1 / OS 10.9.4 / CUDA 6.5.18 / Decklink 4K Extreme / Desktop Video 10.2.1/
DaVinci Resolve 11.1

I want to record to hd deck via resolve power mastering.

Remote control and assemble recoding are has no problems except no sdi audio output.

Decklink's analog xlr audio output and aes/ebu bnc audio output are good.

But SDI audio output is no!!!

Resovle v.10.xx had same problems.

There are special setting for edit to tape in resolve and decklink ?

Is there SDI audio when you are on the Color page playing the timeline?

I 'm absent for a few days in my offce. So i can't check right now.
In addition, I don't have sdi monitor which included speaker.
Usually while i doing resolve work, i hear audio from monitoring speaker (analog xlr input).

BTW, Your question has relation with my question? What?

I can't understand why only sdi audio can't output? AES/EBU & Analog audio output are good!!!

Give me advise please~

I want to see if the SDI issue only occurs during recording to tape, or if it never works.

Try using Media Express, and see if it has the same issue.

We are having the same issue since upgrading to 11. What we have found so far is that when you output to a Sony SR channels 1-8 do not go across but when we output to a D5 the audio is good, the audio also appears to be good on a Tektronix WFM 5200.

The audio appears to be ok while using Media Express.

We have two systems and both are experiencing the same issue.

We are using:

Davinci Resolve 11.1 Desktop Video 10.2.2
Supermicro 7047 GT-TRF
Decklink 4k Extreme
Windows 7 Pro

As a test, go to Windows Control Panel - Programs and Features, and uninstall Desktop Video.

Then install Desktop Video 9.8. This is available on the BMD web site Capture and Playback Support area.

See if that changes the behavior.

Same problem here. I'm running OSX 10.8.5
Desktop Video 10.3.2
Decklink 4K extreme

I can get SDI audio when using Avid Media Composer and BM Media Express.
But in Resolve there is nothing. The audio meters are bouncing away but nothing goes down the SDI.
If I switch to system audio I can here everything fine.
Everything worked back in v9

We've had this problem with output to our digital cinema projector with all versions of Desktop Video 10.x.x from both an UltraStudio 4K (on OS X) and a DeckLink SDI 4K (on Windows). It's just Resolve. Media Express works fine. If I take Resolve's output and run it through the Teranex, setting the output format to the same as the input format (usually 2K DCI for the cinema projector), suddenly audio works again. The Teranex seems to 'clean up' whatever the projector doesn't like about the output from the UltraStudio/DeckLink devices.

I called BMD support about this perhaps a month ago, and the tech told me they'd had reports of this on some other pro gear (he specifically mentioned Sony decks). My guess would be the SDI signal is slightly out of spec, and some gear is really picky about what input it will accept.

It seems the Decklink HD Extreme 3D doesn't have this issue, but the Decklink 4k Extreme does.

We have the same problem, to get sound from Resolve we use Desktop Video 9.x.x, anyway we would like to see this issue fixed.
