I have also just been noticing this on my Zino HD (Dell Inspiron 410) with the
ATI Mobility HD5400 series card. I get sound if I install the Catalyst driver
(but the picture is absolutely horrible). I get a perfect picture with the
radeon open source driver but no sound. If it is any help, I captured alsa-info
output for the same hardware with the different drivers. Pretty much everything
is near identical till it gets to the very end with the dmesg output where
there are lots of HDMI hotplug events with the Catalyst driver and no such
events with radeon.

Links to the alsa-info and my other experiences with the system can be found
