It's a bit hard to judge right now.  So far, many HDMI devices seem
not working even though it appears set up properly.  I've heard that
ATI HDMI devices are working, but others are not well, e.g. on some
devices only left channel is output and on others silent.

Moreover, I'm not pretty sure whether HDMI is connected from the
digital out of STAC codec.  On many devices (e.g. ASUS ones), there is
a dedicated codec for the HDMI transmitter.

So, right now, it's total lack of (hardware) information,

We may try some verbs for HDMI that are not used in the current ALSA
code, at least.  These verbs were extended later...
