how did you test 2.1 speakers ?


have you try hda-jack-retask to fix the pin default of missing subwoofer ?

do you mean surround21 setup does not work ?



if node 0x17 does not work, you need to try the other unconnected stereo
pin complex (e.g. node 0x16 , 0x18, 0x21)


using hda-emu with pin fixup,

do you mean no sound when the two headphone jack share the same volume
control ?

autoconfig: line_outs=2 (0x15/0x17/0x0/0x0/0x0) type:speaker
   speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
   hp_outs=2 (0x1b/0x19/0x0/0x0/0x0)
   mono: mono_out=0x0
     Internal Mic=0x12

==> Best config: lo_type=1, wired=1, mio=1
multi_outs = 15/17/0/0 : 3/2/0/0 (type SP)
  out path: depth=3 :03:0d:15
  out path: depth=3 :02:0f:17
hp_outs = 1b/19/0/0 : 4/4/0/0
  hp  path: depth=3 :04:0e:1b
  hp  path: depth=3 :04:0e:19
