Same issue here on CoreBook X Pro. Speakers stopped working after switching back to Windows 11 (touchpad recovered fine, but audio didn’t). Windows Update shows drivers as “up to date” but Device Manager confirms it’s running the generic Microsoft “High Definition Audio Device” driver, not a Realtek-specific one — codec ID is HDAUDIO\FUNC_01&VEN_10EC&DEV_0269&SUBSYS_27820232&REV_1001.
Could you please provide the correct audio driver package for my serial number?
Serial number: YCoBXpIY9H230200432
BIOS version: ADL-P_EM_IDL918_SUB1_V0.59.8
