Please describe the problem you’ve encountered in detail:

  • Description: I purchased two Lenovo Chromebook 100e Gen 3 laptops from an organization. Both devices arrived with the stock ChromeOS bootloader and were configured as managed devices. I reflashed the BIOS using MrChromebox.tech firmware and installed the latest version of FydeOS. After installation, sound output stopped working entirely. The devices feature an integrated Realtek ALC5682I-VD codec, which seems to be unsupported or undetected by FydeOS.
