This is basically Realtek ALC269 codec itself, so putting this here
may hit with many other machines.

Doesn't it has any proper PCI or codec SSID?  The lack of them usually
means a bug of BIOS.

Sorry for that, there is no proper PCI or codec SSID. We have fixed this 
by writing the firmware. So this patch is useless.
