--- Comment #9 from Andy Furniss adf.lists@gmail.com --- I have a new TV now and can't get hdmi audio working at all.
Maybe my use/setup of alsa doesn't help, but IIRC I did try and fail with a fedora live USB as well.
It works perfectly if I boot into Windows 7, so I know this TV/card combo is OK.
