Hey, I’m facing the same issue on the SER8 too, and I honestly think it’s not about whether you’re using Arch, Fedora, or Debian—it’s all about Realtek, and it could even be tied to the BIOS settings! My gut feeling is that the analog audio only works with that super-special Windows driver, but there might be a BIOS-related tweak that could unlock it. It’s all a bit of a mystery, but adjusting some settings in there might help fix it!"
