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
