Unable to set number of output channels for Audio Render I can't seem to find where to set the number of output channels for an Audio Render. I can control the output format for live playback in preferences but this seems to have no effect on audio rendering. The documentation suggests there should be a button or setting in the scene's output panel but on my version it doesn't seem to be there.
Am I looking in the wrong place? Also peeked through the parameters for the sound.mixdown operator and it doesn't seem to be settable there, nor is it available on bpy.context.scene.
I'm running 2.90.0 on Mac OS X Catalina.
The audio options are visible once you choose ffmepg video as File format.
Then you can set the audio codec and channels in the audio section of the encoding.
