The seller saying there’s a setting that routes the analog voices away from L&R/Phones, that it’s set that way by default after a factory reset, and that I need to find it and route analog back to the main outs before I can hear it. But I’ve been all up and down the menu with no luck.

But there are hundreds of menu options, so it’s not impossible to think I’ve missed it. To those who own one, does this sound like a real thing? Or a seller making excuses for broken kit?
