Re: [PATCH] Fixed no headphone sound bug on laptop Samsung Notebook Pen S, by using exsisting patch Linus' tree as commit 14425f1f521f (ALSA: hda/realtek: Add quirk for Samsung Notebook). This laptop uses same ALC298 but different subsystem id 0x144dc812. So I add SND_PCI_QUIRK at sound/pci/hda/patch_realtek.c
