Hello,
and that seems to be the same for other vt1718s codec implementations
(by asrock): https://launchpadlibrarian.net/70606587/Card0.Codecs.codec.0.txt
 (motherboard ASRock H55M Pro, more info at
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/772638 ),
therefore your code seems to access a non-existing connection. Since
such looks like not very safe/correct, Raymond Yau had suggested to
change it into:

{0x21, AC_VERB_SET_AMP_GAIN_MUTE, AMP_IN_UNMUTE(5)},


{0x21, AC_VERB_SET_AMP_GAIN_MUTE, AMP_IN_MUTE(4)},

I only suggest you to ask Lydia who have submited a patch which change
this non-existing connection
