According to the bios info, the jacks on my system get reported as: Node 0x0b: [Jack] Mic at Ext Front Node 0x0f: [Jack] Line Out at Ext Front Node 0x1e: [Jack] SPDIF Out at Ext Front With alsamixer: Speaker -- effects the internal built-in speaker volume Front -- effects the volume of the headphone jacks Master -- effects both Speaker and Front volume Using hda-jack-sense-test: Pin 0x0b (Black Mic): present = left jack/connector on the front (microphone) Pin 0x0f (Green Line Out): present = middle *and* right jack/connector on the front (headphones) - Reece
