HD60s+ Analog Audio Interference

[J_Pisciotta]

When I open the Elgato 4k Capture Utility and set the audio to "Analog" and save the changes, the analog audio works perfect. (within the capture utility software)

However, when I open OBS and select the scene with the capture card as the Video Capture Device Source the audio mixer shows the audio at ~30% (yes, I've confirmed the microphones are off lol) and I can hear interference on my live stream feed.

I've searched the internet relentlessly and cannot find a solution anywhere. If anyone has ideas I would be very grateful.

Important Notes:
I'm running 2 capture cards at the same time. (2 different video feeds that I need within the same scene). Setting both to "Analog" audio doesn't resolve this.

OBS Version: 27.2.4 (64-Bit Windows 10) I can't upgrade OBS due to needing virtual audio cables for streaming on Zoom (like the video chat service, not the H6 recorder)

That should have nothing to do with it. Go ahead and upgrade. But be aware that you'll have to thoroughly document everything beforehand, essentially install OBS and plugins from scratch, and rebuild manually from your documentation. Some plugins are obsolete, with their functionality being absorbed into OBS itself, and some were abandoned at that point and forked by someone else to support the later versions of OBS, so your original download link for those plugins needs to be replaced with whatever the new one is.

But needing loopbacks has nothing to do with a version freeze. No app knows about that or cares. Physical and virtual are in the same list and behave the same, and the name is only a meaningless string of symbols. If you can drive a speaker and pick up a mic, then you can use a loopback. Period.

For your primary question, I think you're trying to combine too many functions into one device that's not really designed to do that. I think the capture card is meant to *switch* between inputs, not mix them or present them separately.

Or if you do want to *replace* the HDMI audio, I still wouldn't use a capture card to do that. Mute the capture card instead, and bring the analog audio in through its own separate interface.
