Do you mean

LOUT1 playback volume control at node 0x8 affect the volume of your
headphone and LOUT2 playback volume control at node 0x9 affect the volume of
your speakers ?

If you look at 4.1 Block Diagram of alc260 datasheet ,

LOUT1 is connected to 0xf Line Out and
LOUT2 is connected to 0x10 HP
