HDMI audio does not work with HD4200 IGP but does work with radeonhd

Description
I've been using the radeonhd driver for some time due to the fact that it supports audio over HDMI, so i can have everything routed to my HDMI receiver over one cable.
I read that recently the radeon driver was supposed to offer support for this as well, and since it's otherwise a better driver i thought i'd give it a go. unfortunately, i am greeted with the sound of silence, and not hte simon and garfunkel version (which would equally be surprising, but...). if i switch my xorg config to use the radonhd driver audio still works on this machine, but without running x or with x running and radeon driver loaded, nothing.
alsa sees the devices, and I can play to it via sox, but I don't hear anything.
here's some info that might be useful, please let me know if you need anything else.
