At first, I thought it was a problem with the Elgato HD60X. Since updating OBS, the left and right audio of the HD60X has not been balanced. However, when I tried Streamlabs Desktop, I found that the left and right were balanced, and I realized that this was not a problem with the HD60X, but a problem with OBS.

Steps to Reproduce

use Elgato HD60X in OBS 30.2.2
I tried OBS 30.2.1 and OBS 30.2, but they have the same audio balance issue.
I also tried OBS 30.1.2, which I remember doesn’t include this bug, but it has the same issue. I think it’s caused by macOS compatibility problems.

Anything else we should know?

Start by reviewing the linked OBS log and reproducing the Elgato HD60X capture behavior on macOS 15.1 with OBS 30.2.2, comparing left and right channel levels. Trace the audio capture path involved and verify the fix against the reported OBS versions, with completion meaning balanced channels in OBS as in Streamlabs Desktop.
