you need to use hdajacksensetest to verify hp, line out , line in jacks are
node 0x19, 0x14 and 0x1a by plug and unplug those jacks

clear bit 8 of pin default of Line Out Jack if it return correct jack state


> Should have noted, if not clear from the physical ports, no, the machine
does not have outputs for 5.1 surround sound.
