The codec ACPI ID MX98357A exists on CML with rt5682 and rt1011 board through the codec is not present on the hardware, this will mislead the kernel to load a wrong driver, and cause this speaker issue.
As I synced with kernel team, adjust the order of the acpi mach table is dark magic, and may not be accepted by upstream, and I will push coreboot team to fix this and eliminate MX98357A on CML with rt5682 and rt1011 board.
