use hda*verb to find the widget cap of node 0x3e
post the output of
sudo ./hda-verb /dev/snd/hwC0D0 0x3e 0xf00 0x9
if return valhe is 0x200500
try to find out the length of the connection List of node 0x3e
sudo ./hda-verb /dev/snd/hwC0D0 0x3e 0xf00 0xe
if value is not zero , try to find out the connection list of node 0x3e
sudo ./hda-verb /dev/snd/hwC0D0 0x3e 0xf02 0x0
the return value is the node which node 0x3e connected to
check whether the widget is similar to
