try

sudo ./hda-verb /dev/snd/hwC0D0 0x3e 0xf00 0x9

do it return following wcaps ?

 nid = 0x3e, verb = 0xf00, param = 0x9
 value = 0x200500

sudo ./hda-verb /dev/snd/hwC0D0 0x3e 0xf00 0xe

do it return number of connection
 nid = 0x3e, verb = 0xf00, param = 0xe
 value = 0x1

sudo ./hda-verb /dev/snd/hwC0D0 0x3e 0xf02 0x0

di it return the nodes in the connection list
 nid = 0x3e, verb = 0xf02, param = 0x0
 value = 0x1c

repeat the above test wit node 0x3d

Node 0x3d [Audio Selector] wcaps 0x300501: Stereo
  Power states: D0 D1 D2 D3
