I've already installed that and gone through the various HDMI
controller choices, but still nothing, It's driving me crazy that
Myth's sound works except for the internet video stuff. (or if I want
to watch a show on a site on the TV).

It's so bizarre that what worked for 18 months has been borked by
12.04, but just a quick search will show you how many people were
bitten by sound issues with 12.04.

For those of you with 12.04 that do have all your sound working (myth,
flash, apps, etc) did you do a clean install or an upgrade? I filed a
question on launchpad with all the debug info:
