did your graphic driver enable audio support ?
your Samsung hdmi monitor already provide EDID to the graphic but seem
audio is support is not enabled
there are two ways to provide hdmi
1) the iec958 control of spdif of alc663 may block the nvidia HDMI codec
2)
your nvidia HDMI codec may appear as device 3 if you use hda jackretask
to disable digital output （DEVICE 1）by changing pin default of 0x1e from
[Jack] to [N/A]
Node 0x06 [Audio Output] wcaps 0x611: Stereo Digital
Control: name=IEC958 Playback Con Mask, index=0, device=0
Control: name=IEC958
