Hi everyone, I’m having an issue configuring audio in OBS Studio 31.0.2 (64-bit) on Windows 11, using a Blackmagic DeckLink Studio with Blackmagic Desktop Video Setup 14.5.
I’m capturing embedded audio from the SDI signal, and OBS correctly recognizes channels 1 and 2. However, when I try to add channels 3 and 4 independently, the software mixes all the audio into the output. That means the streaming SRT contains 4 audio channels, but all of them are mixed together. I need the audio channels to remain separate instead of being combined.
In OBS’s Advanced Audio Settings, only one input device (Blackmagic) appears, and I can’t find a way to separate channels 3 and 4 to process them independently.
Each audio channel to remain separate in OBS, without being automatically mixed.
To know if there’s a setting in OBS or Blackmagic Desktop Video that allows this.
If there is any plugin or additional tool that could help.
Any help would be greatly appreciated. Thanks in advance!
