There are definitely for the onboard sound, not for HDMI.
The "SB" card has many more mixers (counting 10) and Windows XP also shows about that many for SB. But neither in Linux nor Windows does the SB card have any effect; I do have to turn the bars of the "HDMI" one.
Abnormal, well. It's (semi-)embedded, what did you expect.
Wow, then is the HDMI cable connected inside the device?
Possibly. It looks quite embedded behind the casing - no recognizable connectors, just soldering and wiring onto headers.
Anyway, "IEC958 Playback Switch" should be turned on for HDMI.
% amixer -c1 IEC958 on
Well that does nothing. As there is no PCM channel for it, there is no /dev/snd/pcmC1*, and thus mplayer - or any other progarm - won't even try to output anything.
There is /dev/snd/pcmC1D3p. This should corresponds to HDMI output. Try "aplay -vv -Dhdmi:1 foo.wav" or so.
