Why do you think internal 5.1 speaker is better than external 5.1
speakers?

As the parser put those jacks similar to those 3stack desktop, those three
jacks need to share volume control with internal speakers

autoconfig: line_outs=1 (0x17/0x0/0x0/0x0/0x0) type:line
    speaker_outs=3 (0x14/0x16/0x15/0x0/0x0)
    hp_outs=1 (0x1b/0x0/0x0/0x0/0x0)
    mono: mono_out=0x0
    dig-out=0x1e/0x0
    inputs:
      Internal Mic=0x12
      Mic=0x18
      Line=0x1a
