I feel like I am getting so close, but the screenshots don't match. I'm on a 2021 Macbook (with Monterey) and using an Easycap type video capture to digitize VHS tapes. I'm finally getting a pretty good video signal but no audio. I installed Blackhole and selected it in my Sound>Input on the Mac and then added an audio input source in OBS but still nothing....suggestions?
Funny, I already spent 2 hours trying to figure out what's wrong, found this thread and these illustrations. I thought: wow finally, someone got exact problem like mine and even steps are exactly the same. I was ready to scroll down to see the question and answer, but then I realised the whole thread is instruction, not question or issue. I give up, I tried blackhole, soundflower, reinstalling obs, different options of OBS with different outputs, inputs, channels, bitrate, exports, different configurations of midi devices, different audio speakers but while Movavi and native recorder can capture the sound, OBS studio does not see it at all.
Precise description of what you have to, with pictures illustrating everything.
Even small details like telling users how to install third party apps and a link on how to install BlackHole via Homebrew (the no-email option) have been added.
Pretty much everything that could be in there is in there.
