It might be also the video driver side.
For example, when a wrong EDID is set up in X config, the audio part also
doesn't work.  There were similar bug reports with the older Nvidia cihpset.

Of course, it can be a driver bug.  How did you test exactly?
A preferred way is to run like:
	% aplay -Dhdmi foo.wav
It might be -Dhdmi:1, too, depending on the h/w.

Let's check firstly from the 2ch samples.
