Audio problems with zoom and rendezvous
In my work, we need to communicate the show host with someone else via zoom or rendezvous. But when we send the transmission through blackmagic 4k extreme, the audio disappears. Before transmitting the signal to the switcher, everything works normally. This happens in both applications. Another issue is sending the return of the switcher to the zoom while the person participates in the program, because when we virtualize the wirecast camera, no other zoom camera input works for us, making it impossible to generate different images when transmitting 4K and virtual cam.

Have updated the Blackmagic Driver to 12.1?
Please explain how you are using BMD 4K Extreme in Rendezvous or Zoom.

You can always switch camera sources in Zoom although it's awkward to do so.

I'm not sure if we use the latest version of software and driver. I will confirm.
Please explain how you are using BMD 4K Extreme in Rendezvous or Zoom.
We use BMD with the exclusive function of sending images and audio to the switcher. Everything goes separate for the board, the images of the switcher, we put in an auxiliary output in the decklink SDI inputs, while 4k extreme sends the meeting back to the studio / switcher
Zoom only allows one camera selection. You can always switch camera sources in Zoom although it's awkward to do so.
we do not switch the cameras in the zoom during the recording, we are sending the image of the studio so that the guest can see what is happening. but, obviously, if I select 4k extreme to make the same transmission that goes to the switcher, it will generate the same image for the zoom. our solution here will be to put an input source for the zoom,
and a different output to the studio, so that they do not send the same signal.
Will I have a problem if I use the BMD output transmitting to 4k extreme and the virtual camera at the same time?
I'm not quite sure I understand this. You can send Wirecast Program Out Virtual Camera to Zoom in which all the guests will see all the live switching.
thank you very much for all the explanations so far, but what we need is to send the image exchange that happens in the switcher and not in the wirecast. the tv program passes by a table (grass valley kayak), in wirecast we integrate the studio with the zoom. our biggest problem is actually the audio. I’ll follow your update guidelines to make sure I’ll get back to you.
I would also like your opinion on a test we did on another audio output. as the 4k audio and video comes embbeded, when we switched the 4k audio output to another source on windows, the problem stopped. the audio card is a synaptics HD. if that would be an alternative or if it is the only way to solve the problem. Remembering that what we need here is for the studio and guests to communicate for live interviews.

while 4k extreme sends the meeting back to the studio / switcherSorry but you must explain technically how one "sends the meeting" back to the studio. You must explain as if you were instructing someone to attach the same equipment to the same software and hardware.

I'm sorry but you really need to explain as if you were presenting a block diagram so an engineer can set up the equipment.
Given this description an engineer would not understand the audio problems
First, update Wirecast and Blackmagic driver and confirm the version.
Then I think you need to simplify the setup to diagnose where the problem is.

We made the updates, everything worked perfectly, but unfortunately, after testing the zoom meeting and saving the project, and configuring a new meeting through rendezvous, it was left without audio. The audio modulates inside the wirecast, but we don't hear it. All settings are as they should be.

Perhaps a monitor setting changed after testing in Zoom and saving.-
CraigS In fact, there is a kind of overlap in the audio output. The zoom reunion sound cuts off when opening the wirecast. When we switch the audio output to a card other than blackmagic, like a synaptics HD audio, for example, boom, it works for everything. We kept all the settings that worked previously. It looks like a kind of conflict.
-
Pedro We'd want to strip this down to the simplest setup to confirm where the conflict is. You have a complex setup so without a block diagram or signal flow chart it would be hard for us to troubleshoot.
