As much as we complain about the audio problems with HDMI implementation, it's the problems it has with display compatibility that gets the most attention. SimplayHD was set up by Silicon Image as a way to certify (and, by way of another logo, indicate to consumers) that source components will play nice with any HDMI capable display, which (as you might expect) is not an uncommon problem.

It is sad that SI don't see these audio issues coming, and work to include or develop a certification for audio compatibility as well, in order to keep consumers from losing their minds. It's a telling sign that the considerable audio expertise in this forum is scratching their heads over this issue - just imagine how the general consumer public is likely to react to it.
