do you mean there is another nvidia hdmi codec for HDMI output or provided by secondary digital output of alc663?

If i understand post #2 correct:
The boost speaker is working fine.
Problem: I get video through HDMI, but alsa goes not seem to find the HDMI sound output.
Look at http://ubuntuforums.org/showthread.php?t=2216196 for better description.

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)

http://www.realtek.com/products/productsView.aspx?Langid=1&PFid=37&Level=5&Conn=4&ProdID=165

The ALC663 provides two independent S/PDIF outputs and supports 16/20/24-bit SPDIF output with a sampling rate of up to 192kHz, offering easy connection of PCs to high quality consumer electronic products such as digital decoders and speakers. In addition to the standard (primary) SPDIF output function, the ALC663 features another independent (secondary) SPDIF-OUT output and converters that transport digital audio output to a High Definition Media Interface (HDMI) transmitter (becoming more common in high-end PCs).

if you cannot find nvidia HDMI codec

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]

It's working in win8 so the hardware is good.
