If you check the XBMC page I linked to earlier, you will find that
those devices aren't all equal.

Some can do stereo only and won't work with AC3 or DTS passthrough.

Did you use passthrough in mplayer ?

As above, not all those hdmi devices are equal and some will only work
for stereo, 16 bits audio.

Please understand that the issue is with alsa, you shouldn't have that
many devices to start with. This will probably get fixed in a future
version of the drivers.
