Hi I am running 2.6.28-11-generic (Kubunti install) with M4A78T-E Motherboard and also have no digital spdif output.

I have read this thread ( http://mailman.alsa-project.org/pipermail/alsa-devel/2009-May/016958.html ) and gather that it is a problem with the BIOS and that it was fixable by patching alsa source. As a newbie and not wanting to destroy my alsa source files can you explain or refer me to a good howto of the steps needed?

Thanks
